Detailed Description of Fil É Lectrique Th 1.5mm² - Rigid Copper Cable 450/750V - H07V-U Equivalent - (Color: Blue, Red or Green/Yellow) - 100m Roll
1. From the Perspective of the Product Itself
1.1 Specification Parameters
The Fil É Lectrique Th 1.5mm² rigid copper cable is engineered with precise specification parameters that underpin its compatibility with H07V-U standards and its reliability in low-voltage fixed electrical systems. At the core of its specifications is the 1.5mm² cross-sectional area of the rigid
Copper Conductor, a dimension determined through rigorous electrical engineering analysis to optimize current transmission for low-to-medium power applications. This cross-sectional area is calibrated to ensure the conductor can carry the rated current specified by the H07V-U standard—typically a continuous current of approximately 16A to 20A, depending on the installation environment (e.g., ambient temperature, grouping of cables). This current-carrying capacity is sufficient to power low-to-medium load devices, ensuring minimal voltage drop (≤2.5% under full load) over the length of the cable, which is critical for maintaining the efficiency and stability of fixed electrical systems.
The cable’s rated voltage of 450/750V is a dual rating that serves distinct functional purposes. The 450V rating represents the maximum working voltage, meaning the cable can operate safely in low-voltage power distribution systems where the nominal voltage does not exceed 450V—this aligns with the voltage requirements of most residential, commercial, and industrial auxiliary electrical networks. The 750V rating, known as the rated insulation voltage, indicates the maximum voltage the insulation layer can withstand without electrical breakdown. This higher rating provides a safety margin against voltage fluctuations or transient overvoltages (e.g., those caused by lightning or equipment switching), preventing current leakage from the conductor to surrounding components and reducing the risk of electric shock or equipment damage.
As an H07V-U equivalent product, the cable adheres to the temperature resistance requirements of the H07V-U standard, operating stably within a temperature range of -30°C to 70°C. This wide temperature tolerance is validated through accelerated aging tests, where the cable is exposed to extreme temperatures for extended durations (e.g., 168 hours at 70°C and 24 hours at -30°C) and its electrical and mechanical properties are re-evaluated. These tests confirm that the conductor retains its conductivity and the insulation layer maintains its structural integrity—no brittleness, cracking, or softening—even under extreme temperature conditions. This makes the cable suitable for installation in environments with varying temperatures, from unheated outdoor junction boxes to indoor spaces near heat-generating appliances.
The rigid copper conductor of the cable has defined specifications for diameter and tensile strength. The conductor has a nominal diameter of approximately 1.38mm, with a tolerance of ±0.02mm, ensuring uniformity in cross-sectional area and current transmission. The tensile strength of the rigid copper conductor is rated at ≥200 MPa, which means it can withstand the mechanical stress of fixed installation (e.g., being pulled through conduit or embedded in walls) without deformation or breakage. This mechanical strength is critical for fixed wiring, where the cable remains in place for long periods and cannot be easily repaired or replaced.
The insulation layer, which complies with H07V-U standards, has precise thickness requirements. The minimum insulation thickness is 0.8mm, with a maximum thickness of 1.0mm, and a tolerance of ±0.05mm. This uniform thickness ensures consistent electrical insulation performance across the entire length of the cable—thin spots in the insulation could lead to dielectric breakdown, while excessive thickness could reduce
Flexibility and compatibility with standard installation components. The insulation layer also has a dielectric strength of ≥20 kV/mm, which is verified through dielectric strength testing (subjecting the cable to 2500V for 1 minute in a water bath) to ensure it can withstand electrical stress without leakage.
In addition to these core parameters, the cable’s overall dimensions are standardized for compatibility with industry-wide installation components. The outer diameter of the cable (including insulation) is approximately 3.5mm to 3.8mm, depending on the insulation color (minor variations due to colorant addition). This outer diameter ensures the cable can fit seamlessly into standard conduit systems (e.g., 16mm or 20mm PVC conduit) and junction boxes, as well as connect to standard terminals and connectors without modification. The cable’s weight per unit length is approximately 0.014kg per meter, which is lightweight enough to be supported by standard wiring hardware in fixed installations without sagging, while still being durable enough to withstand handling during installation.
1.2 Distinctive Uses
The distinctive uses of the Fil É Lectrique Th 1.5mm² rigid copper cable are shaped by its H07V-U equivalent performance, 1.5mm² cross-sectional area, rigid copper conductor, and multi-color insulation, making it a versatile solution for low-to-medium power fixed electrical systems across residential, commercial, and industrial auxiliary sectors.
In residential fixed installations, the cable is primarily utilized in low-to-medium power circuits where reliability and long-term stability are essential. It is commonly employed as the main wiring for lighting circuits throughout the home, connecting ceiling fixtures, wall sconces, and switches to the main electrical panel. Its 1.5mm² cross-sectional area and 450/750V rating ensure it can handle the current demands of residential lighting systems, even when multiple fixtures are connected in a single circuit. The cable is also used for powering ordinary sockets in living rooms, bedrooms, hallways, and kitchens, where it supplies electricity to small household appliances such as lamps, televisions, laptops, and small kitchen gadgets. The rigid copper conductor’s mechanical strength makes it ideal for these applications, as it can be routed through walls, ceilings, and floors without deforming, ensuring a secure and long-lasting installation. The multi-color insulation (blue, red, green/yellow) further enhances its usability in residential settings, allowing installers to easily identify live wires (red), neutral wires (blue), and
Grounding Wires (green/yellow), reducing the risk of wiring errors and improving safety.
In commercial fixed installations, the cable is suitable for low-to-medium power applications in small to medium-sized commercial spaces. In small offices, it is used for wiring desk lamps, computers, printers, and other office equipment, as well as for lighting systems in workspaces, hallways, and meeting rooms. Its stable current-carrying capacity ensures that office equipment operates efficiently without voltage fluctuations, which is critical for maintaining productivity. In retail environments such as convenience stores and small boutiques, the cable is used for powering cash registers, point-of-sale (POS) systems, display lighting, and small refrigeration units. The cable’s H07V-U equivalent performance—including its temperature resistance and insulation reliability—makes it suitable for the varying environmental conditions in retail spaces, such as temperature changes near refrigerators or exposure to dust near entryways. The 100m roll design is particularly beneficial for commercial installations, as it allows installers to cut the cable to the exact length needed, reducing waste and minimizing the number of joints, which lowers the risk of circuit faults.
In industrial auxiliary fixed installations, the cable is employed in low-power auxiliary circuits that support larger industrial operations. It is used for wiring control circuits of small auxiliary equipment, such as conveyor belt sensors, pump controllers, and indicator lights, which are critical for monitoring and operating industrial machinery. The cable’s rigid copper conductor can withstand the slight vibration common in industrial environments, ensuring that connections remain secure and the circuit remains stable. Its insulation layer, compliant with H07V-U standards, provides protection against dust and minor chemical exposure, which are prevalent in industrial settings. Additionally, the cable is used for lighting systems in industrial auxiliary areas such as storage rooms, maintenance workshops, and staff break rooms, where it provides reliable illumination for daily operations and maintenance tasks.
The cable’s fixed installation design is a key factor in its distinctive uses. Unlike
Flexible Cables, which are intended for temporary or movable applications, the Fil É Lectrique Th 1.5mm² cable’s rigid structure and H07V-U equivalent performance make it suitable for permanent wiring that remains in place for the lifetime of the building or equipment. It is commonly installed in concealed locations, such as inside walls, ceilings, or conduit systems, where it is protected from physical damage and environmental exposure. This fixed installation capability makes it a preferred choice for new construction projects, as well as for renovation projects where existing wiring needs to be replaced with a more durable and reliable solution.
1.3 Material and Style
The material composition and style of the Fil É Lectrique Th 1.5mm² rigid copper cable are carefully selected to meet H07V-U equivalent standards and optimize performance in fixed electrical systems.
At the core of the cable is the rigid copper conductor, crafted from high-purity electrolytic copper with a purity level of at least 99.95%. This high purity is essential to minimize electrical resistivity, as impurities in copper can increase resistance and reduce current-carrying capacity. Electrolytic copper is chosen for its superior conductivity—copper has a resistivity of approximately 1.72×10⁻⁸ Ω·m at 20°C, which is significantly lower than other common conductive materials such as aluminum. This low resistivity ensures that current is transmitted efficiently with minimal energy loss, a critical factor in fixed installations where the cable cannot be easily replaced to address inefficiencies. The rigid structure of the conductor offers several advantages over
Stranded Conductors for fixed applications: it has higher mechanical strength, making it more resistant to bending fatigue and breakage during installation and long-term use; it maintains its shape when routed through conduit or embedded in walls, ensuring a consistent wiring path; and it forms more secure and stable connections with terminals and connectors, as there is no risk of individual strands fraying or becoming loose over time.
The insulation layer of the cable is made of polyvinyl chloride (PVC), a thermoplastic material that meets the insulation requirements of H07V-U standards. PVC is selected for its excellent electrical, mechanical, and environmental properties. It has high dielectric strength, which enables it to withstand the 450/750V rated voltage without electrical breakdown, ensuring that the conductor is effectively isolated from surrounding components. PVC also has good
Chemical Resistance, protecting the conductor from corrosion caused by minor exposure to dust, moisture, and common household, commercial, or industrial chemicals (e.g., cleaning agents, oils). Its temperature resistance is another key advantage—it can operate stably in temperatures ranging from -30°C to 70°C, making it suitable for fixed installations in a wide range of environments. Additionally, PVC has high mechanical strength, withstanding the physical stress of fixed installation (e.g., being pulled through conduit, pressed against building materials) without sustaining damage to the insulation layer. The
PVC Insulation is also formulated to be flame-retardant, complying with relevant fire safety standards (e.g., IEC 60332-1), which means it will self-extinguish when exposed to flame, reducing the risk of fire spread in the event of an electrical fault.
In terms of style, the cable features a smooth, cylindrical outer surface, with the PVC insulation layer uniformly extruded around the rigid copper conductor. The insulation layer has a consistent thickness across the entire length of the cable, with no thin spots or irregularities that could compromise its performance. The cable is available in three distinct insulation colors—blue, red, and green/yellow—each serving a specific purpose in electrical systems. Blue insulation is typically used for neutral wires, red for live wires, and green/yellow for grounding wires, adhering to international electrical color-coding standards. This color-coding is applied uniformly during the insulation extrusion process, using high-quality, UV-stable colorants that resist fading over time, ensuring long-term visibility and ease of identification during installation and maintenance.
The cable’s single-core design is another key stylistic feature, making it suitable for fixed installations where a single, dedicated wiring path is required. The single-core design simplifies installation, as it can be easily routed through conduit or embedded in walls without the complexity of separating multiple cores. It also reduces the risk of cross-talk or interference, which can be a concern in
Multi-Core cables used in sensitive electrical systems. The cable’s overall design is compact, with an outer diameter of 3.5mm to 3.8mm, which allows it to fit into tight spaces and standard installation components, such as small junction boxes or narrow conduit systems.
The material and style of the cable are also optimized for compatibility with industry-standard fixed installation components. The rigid copper conductor is compatible with a wide range of terminals, lugs, and connectors, including screw terminals, crimp terminals, and wire nuts, allowing for secure and reliable connections that withstand the test of time. The PVC insulation layer is compatible with common wire stripping tools, making it easy to remove the insulation during installation without damaging the conductor. Additionally, the cable’s outer diameter is standardized to fit into common conduit sizes (e.g., 16mm, 20mm), ensuring that it can be installed in existing or new fixed wiring systems with minimal modifications.
1.4 Production Process
The production process of the Fil É Lectrique Th 1.5mm² rigid copper cable is a highly controlled, multi-stage operation that adheres to H07V-U equivalent standards and strict quality control measures to ensure consistent performance, safety, and reliability. The process begins with raw material selection and progresses through conductor formation, insulation extrusion, color application, testing, and spooling, with rigorous quality checks at each stage.
1.4.1 Copper Conductor Production
The first step in the production process is the manufacturing of the rigid copper conductor. High-purity electrolytic copper ingots (99.95% purity) are melted in a controlled induction furnace at a temperature of approximately 1085°C—this is the melting point of copper. The molten copper is then cast into continuous copper rods with a diameter of approximately 8mm, using a vertical continuous casting machine. These rods are cooled rapidly in a water bath to solidify the copper and maintain its structural integrity. After casting, the copper rods undergo a series of quality checks, including chemical composition analysis (to verify purity) and dimensional inspection (to ensure the diameter is within ±0.1mm tolerance). Any rods that fail these checks are rejected and recycled.
The approved copper rods are then drawn through a series of diamond dies in a wire drawing machine to reduce their diameter to the required 1.38mm. This cold drawing process is performed at room temperature, which enhances the copper’s tensile strength and conductivity by aligning the copper’s crystalline structure. The drawing process is incremental—each pass through a smaller die reduces the diameter by a small amount (typically 5–10%)—to avoid overstressing the copper and causing defects. During drawing, a small amount of non-toxic lubricant is applied to the rod to reduce friction between the rod and the die, preventing surface damage and ensuring a smooth finish. After drawing, the
Copper Wire (now the rigid conductor) undergoes an annealing process to relieve internal stresses caused by cold drawing. The annealing process involves heating the wire to a temperature of 400–600°C in a protective nitrogen atmosphere, which prevents oxidation of the copper surface. Annealing also restores the copper’s ductility, making it more flexible for subsequent processing while maintaining its rigid structure for fixed installation.
Once annealed, the rigid copper conductor is inspected for uniformity in diameter (using a laser micrometer), surface smoothness (via visual inspection and surface roughness testing), and tensile strength (using a tensile testing machine). The diameter must be 1.38mm ±0.02mm, the surface must be free of scratches, pits, or oxidation, and the tensile strength must be ≥200 MPa. Any conductors that fail these inspections are discarded.
1.4.2 PVC Insulation Extrusion
The next stage is the extrusion of the PVC insulation layer, which is critical to meeting H07V-U equivalent standards for electrical insulation and environmental protection. The rigid copper conductor is fed into a single-screw extrusion machine, where PVC resin is mixed with additives—including plasticizers (to enhance flexibility), stabilizers (to prevent thermal degradation), flame retardants (to meet fire safety standards), and colorants (to achieve the desired blue, red, or green/yellow color)—in a heated mixing chamber. The mixture is melted at a temperature of 180–220°C, with precise temperature control to ensure the PVC flows uniformly and does not degrade.
The molten PVC is then forced through a circular extrusion die that surrounds the copper conductor. The die is designed to ensure that the PVC insulation has a consistent thickness of 0.8mm to 1.0mm (±0.05mm) around the conductor. The extrusion speed is synchronized with the speed of the conductor feed to maintain uniform insulation thickness along the entire length of the cable. After extrusion, the
Insulated Cable is cooled rapidly in a water bath maintained at 20–30°C to solidify the PVC. The cooling rate is controlled to prevent the formation of bubbles or cracks in the insulation layer—too rapid cooling can cause thermal shock, while slow cooling can lead to uneven solidification and surface defects.
Once cooled, the insulated cable is inspected for insulation thickness (using a laser thickness gauge), uniformity (via visual inspection of the surface), and adhesion to the conductor (by attempting to peel the insulation from the conductor). The insulation must adhere tightly to the conductor—any insulation that peels easily is rejected. The cable is also checked for color consistency, ensuring that the blue, red, or green/yellow color is uniform and matches the required shade standards.
1.4.3 Quality Testing
Quality testing is an integral part of the production process, conducted at multiple stages to ensure the cable meets H07V-U equivalent standards and performance requirements. Key tests include:
Conductor Resistance Test: The electrical resistance of the rigid copper conductor is measured using a micro-ohmmeter at 20°C. The resistance must be ≤12.1Ω per kilometer—this ensures that the conductor has low resistivity and can transmit current efficiently. Any conductor with resistance exceeding this limit is rejected, as it indicates impurities in the copper or an undersized cross-sectional area.
Dielectric Strength Test: The insulated cable is submerged in a deionized water bath (to simulate damp installation conditions) and connected to a high-voltage power supply. A voltage of 2500V is applied to the conductor for 1 minute, and the leakage current is measured. The leakage current must not exceed 1mA—this confirms the insulation layer’s ability to withstand electrical stress without breakdown. Cables that fail this test (e.g., leakage current >1mA or insulation breakdown) are discarded.
Insulation Resistance Test: Using a megohmmeter, the insulation resistance between the copper conductor and the external environment is measured at 20°C. The insulation resistance must be ≥100MΩ per kilometer, ensuring the PVC layer effectively isolates the conductor and prevents current leakage. Low insulation resistance values indicate contamination or defects in the insulation, leading to rejection.
Temperature Resistance Test: The cable is subjected to two extreme temperature cycles. For high-temperature testing, it is placed in a forced-air oven at 70°C for 168 hours (7 days). After removal, it is cooled to room temperature, and its insulation resistance and dielectric strength are retested—no significant degradation (≥80% retention of original values) is allowed. For low-temperature testing, the cable is stored in a freezer at -30°C for 24 hours, then immediately bent around a mandrel with a diameter 4 times the cable’s outer diameter. The insulation is inspected for cracks or splits; any visible damage results in rejection.
Flame Retardancy Test: Conducted in accordance with IEC 60332-1, the test involves vertically mounting a 600mm length of cable and applying a 1kW flame to its lower end for 60 seconds. After removing the flame, the cable must self-extinguish within 60 seconds, and no flaming droplets are allowed to ignite a cotton pad placed 500mm below. This ensures the cable meets fire safety requirements for fixed installations.
1.4.4 Spooling and Labeling
After passing all quality tests, the cable is wound onto 100-meter spools in a fully automated spooling machine. The spools are made of high-density polyethylene (HDPE) plastic, selected for its durability, moisture resistance, and compatibility with construction site storage. HDPE spools have a central core diameter of 75mm and flange diameter of 200mm, designed to support the 1.4kg weight of the 100m cable (1.5mm² variant) without deformation. The spool’s flange edges are rounded to prevent damage to the cable’s insulation during winding and unwinding.
The spooling process is controlled by a computerized system that maintains constant tension (8–10N) to ensure the cable is wound in tight, uniform layers. This prevents tangling, which would complicate installation, and ensures consistent unwinding speed. A length-measuring encoder integrated into the machine counts the cable length, stopping automatically once 100 meters are wound—this eliminates under-length or over-length spools. For color-coded cables (blue, red, green/yellow), separate spooling lines are used to avoid cross-contamination of colors.
Once spooled, each spool undergoes a final visual inspection to confirm the cable is evenly wound, the spool is undamaged, and the insulation color is consistent. A weather-resistant, UV-protected label is then applied to the spool’s flange. The label includes comprehensive product information:
This labeling ensures full traceability—if quality issues arise, the lot number allows the manufacturer to identify the production batch and implement targeted recalls if necessary.
2. From the Perspective of Product General Information
2.1 Packaging
The packaging of the 100m spooled cable is engineered to protect the product during storage, transportation, and on-site handling, while supporting efficient installation.
Primary Packaging (Spool Protection)
Each HDPE spool is wrapped in a 50μm-thick low-density polyethylene (LDPE) film. The film is applied in a spiral pattern with 50% overlap, creating a waterproof and dustproof barrier. A tear tab is positioned at the outer edge of the film, allowing installers to unwrap the cable incrementally during use—this avoids full exposure to dirt or moisture before installation.
Secondary Packaging (Individual Spools)
For orders of 1–5 spools, each wrapped spool is placed into a single-walled corrugated cardboard box (230mm × 230mm × 100mm). The box interior is lined with recycled paper padding to prevent spool movement during transit. The box is sealed with water-activated tape (more secure than adhesive tape) and labeled with the same product information as the spool label, plus shipping details (destination address, tracking number) and handling instructions (“Store Upright,” “Do Not Stack Over 5 Units”).
Bulk Packaging (Palletized Shipments)
For orders of 10+ spools, spools are consolidated onto heat-treated hardwood pallets (1200mm × 800mm) to comply with ISPM 15 international shipping regulations. Each pallet holds 40 spools (arranged in 5 rows of 8), separated by cardboard dividers to prevent friction between spools. The entire pallet is wrapped in 3 layers of 25μm stretch film (LDPE) to secure the load, and 4 polyester straps (each with 500N tension) are applied horizontally and vertically for reinforcement. Plastic corner protectors are added to the pallet’s edges to prevent strap damage to the cardboard boxes.
Sustainability Features
All packaging materials are recyclable: HDPE spools, LDPE film, and corrugated cardboard are accepted by most municipal recycling programs. The manufacturer offers a spool recycling program—customers can return used spools to designated collection points, where they are cleaned, inspected, and reused for future production. Additionally, cardboard boxes are made from 80% recycled paper, and no non-recyclable adhesives or coatings are used.
2.2 Transportation
The transportation process prioritizes product integrity, on-time delivery, and compliance with global logistics standards.
Logistics Partner Selection
Logistics partners are evaluated based on 3 key criteria:

Pre-Transport Inspection
Before dispatch, each shipment is inspected:
Compromised packaging is repaired or replaced—e.g., torn stretch film is re-wrapped, damaged boxes are substituted.
Mode of Transportation
The mode is selected based on shipment size, distance, and urgency:
Domestic Road Transport: Used for shipments within a single country (e.g., France, Germany). Trucks are equipped with air suspension to minimize vibration (≤0.5g) and climate-controlled cargo areas (5°C–30°C, ≤60% humidity) to protect the PVC insulation from moisture or thermal stress.
Cross-Border Rail Transport: Preferred for bulk palletized shipments (≥5 pallets) across Europe. Railcars are enclosed, with temperature monitoring sensors and reduced vibration compared to trucks. Transit time is 2–3 days for most European routes, with lower carbon emissions than road transport.
International Sea Transport: Used for non-urgent global shipments (e.g., to Asia, Africa). Palletized spools are loaded into 20-foot dry containers, with 1kg desiccant packs per 10 spools to absorb marine humidity. Containers are sealed with tamper-evident tape and labeled “Waterproof” and “Handle With Care.”
International Air Transport: Reserved for urgent orders (e.g., replacement spools). Spools are packed in reinforced cardboard boxes with foam padding, and shipped via express couriers (DHL, FedEx) for 3–5 day delivery. Boxes are labeled “Urgent” and “Fragile” to prioritize handling.
Shipment Tracking and Communication
Customers receive a unique tracking number once the shipment is dispatched, accessible via the manufacturer’s portal or logistics partner’s app. The portal provides real-time updates (location, estimated arrival, customs status).
