I. Product-Specific Details
1. Specification Parameters
The aluminum core, single-stranded, PVC insulated, PVC
Sheathed Cable is engineered with precise specifications to ensure optimal performance across diverse electrical applications. These parameters are critical for determining the cable’s suitability for specific projects, from residential wiring to industrial power distribution.
Conductor Characteristics
The core of the cable consists of a single-stranded
Aluminum Conductor, which is defined by its diameter, cross-sectional area, and conductivity. Common conductor sizes range from 1.5 mm² to 240 mm², accommodating current ratings from 10 A to 400 A, depending on the application and installation conditions. The single-stranded design ensures uniformity in electrical flow, minimizing resistance and energy loss. The aluminum used is typically 99.5% pure, with trace elements (such as copper or magnesium) added to enhance tensile strength and corrosion resistance. This alloy composition ensures the conductor can withstand mechanical stress during installation and maintain conductivity over time.
Insulation and Sheathing Dimensions
The
PVC Insulation layer surrounding the aluminum core has a thickness ranging from 0.6 mm to 3.0 mm, depending on the conductor size and voltage rating. This layer is designed to provide dielectric strength of at least 15 kV/mm, ensuring safe operation at voltages up to 600 V for general-purpose cables and up to 1000 V for industrial applications. The outer
PVC Sheath adds an additional 0.8 mm to 4.0 mm in thickness, contributing to the cable’s overall diameter, which ranges from 3.5 mm (for 1.5 mm² conductors) to 30 mm (for 240 mm² conductors).
Voltage and Temperature Ratings
The cable is rated for nominal voltages of 0.6/1 kV (phase-to-ground/phase-to-phase), making it suitable for low-voltage power distribution systems. It operates efficiently within a temperature range of -20°C to +70°C, with short-term overload capacity up to +90°C for durations not exceeding 5 seconds. This temperature tolerance ensures reliable performance in both cold climates (e.g., outdoor installations in winter) and warm environments (e.g., indoor wiring in poorly ventilated spaces).
Mechanical Properties
The cable exhibits a minimum bending radius of 6 times its outer diameter for fixed installations and 10 times for flexible applications, allowing for easy routing around obstacles. Its tensile strength is rated at 12 N/mm² for the conductor and 15 N/mm² for the PVC layers, ensuring resistance to stretching during installation. Additionally, the cable is flame-retardant, meeting IEC 60332-1-2 standards, which require it to self-extinguish within 60 seconds of removing an ignition source.
2. Unique Applications
The versatility of this cable stems from its ability to adapt to both indoor and outdoor environments, making it a preferred choice across residential, commercial, industrial, and infrastructure sectors.
Residential Applications
In homes, the cable is used for main power supply lines, connecting distribution boards to outlets, lighting fixtures, and major appliances (e.g., refrigerators, air conditioners). Its single-
Stranded Conductor simplifies termination in junction boxes, while the PVC sheathing protects against accidental damage from furniture or renovation work. For outdoor residential use, it is ideal for wiring garden lighting, pool pumps, and outdoor sockets, as the sheath resists moisture and UV radiation.
Commercial Buildings
In offices, shopping malls, and hotels, the cable facilitates power distribution to HVAC systems, elevators, security cameras, and POS terminals. Its flame-retardant properties are crucial in high-occupancy spaces, reducing fire risks. The cable’s
Flexibility allows it to be installed in tight spaces, such as ceiling cavities and wall ducts, without compromising performance.
Industrial Facilities
Factories and manufacturing plants rely on this cable for powering machinery, conveyor belts, and control systems. Its resistance to oils, chemicals, and mechanical stress makes it suitable for harsh industrial environments. For example, in food processing plants, the PVC sheath withstands frequent cleaning with water and sanitizers, while in automotive factories, it resists exposure to lubricants and coolants.
Infrastructure Projects
The cable is widely used in infrastructure, including street lighting, traffic signal systems, and underground power distribution networks. Its durability makes it suitable for direct burial (with proper bedding) in soil or concrete, protecting against rodent damage and soil pressure. Overhead installations, supported by poles or brackets, benefit from its lightweight design, reducing strain on support structures.
3. Material and Design Features
The cable’s performance is directly influenced by its material composition and structural design, which work in tandem to ensure safety, efficiency, and longevity.
Aluminum Conductor
Aluminum is chosen for its favorable strength-to-weight ratio (2.7 g/cm³, compared to copper’s 8.96 g/cm³), reducing installation labor and transportation costs. While its conductivity (377 S/m) is lower than copper’s (580 S/m), the larger cross-sectional area of
Aluminum Conductors compensates, ensuring equivalent current-carrying capacity at a lower cost. The single-stranded design eliminates the need for stranding, simplifying manufacturing and reducing the risk of internal corrosion between strands.
PVC Insulation
The insulation layer is made from rigid PVC compound, formulated with plasticizers to enhance flexibility and stabilizers to resist thermal degradation. This material is inherently resistant to water, acids, and alkalis, preventing current leakage and short circuits. The insulation is color-coded (e.g., black for phase conductors, blue for neutral) to facilitate correct wiring, adhering to international standards like IEC 60446.
PVC Sheath
The outer sheath uses a heavy-duty PVC compound with added UV stabilizers and antioxidants, enhancing its resistance to weathering. Unlike insulation-grade PVC, the sheath contains higher concentrations of fillers (e.g., calcium carbonate) to improve mechanical strength and reduce cost. It is available in standard colors (black, gray) or custom colors for easy identification in complex wiring systems.
Structural Integrity
The cable’s layers are bonded during manufacturing to prevent delamination, ensuring that the insulation and sheath remain intact even when bent or stretched. This bonding also enhances moisture resistance, as it eliminates gaps where water could seep into the conductor.
4. Manufacturing Process
The production of this cable involves a series of precision steps, from raw material preparation to final testing, ensuring compliance with international standards (e.g., IEC 60502, ASTM B800).
Conductor Formation
Aluminum ingots are melted and cast into rods, which are then drawn through dies to reduce their diameter to the required size (e.g., 2.5 mm for a 4 mm² conductor). This drawing process increases the conductor’s tensile strength through work hardening. The single strand is annealed to remove internal stresses, ensuring flexibility during installation.
Insulation Extrusion
The aluminum conductor is fed into an extrusion machine, where molten PVC (heated to 180–200°C) is applied uniformly around it. The extrusion die is calibrated to ensure precise insulation thickness, with online monitoring systems checking for defects (e.g., voids, uneven coating). The
Insulated Conductor is then cooled in a water bath to solidify the PVC.
Sheath Application
The insulated conductor is passed through a second extrusion machine to apply the outer PVC sheath. This layer is extruded at a slightly lower temperature (170–190°C) to avoid damaging the underlying insulation. The sheath is bonded to the insulation using a proprietary adhesive layer, ensuring adhesion even under thermal stress.
Quality Testing
After production, each cable undergoes rigorous testing, including:
Cables that pass all tests are spooled onto reels (ranging from 50 m to 1000 m) and labeled with specifications (e.g., conductor size, voltage rating, batch number) for traceability.
II. General Product Information
1. Packaging
The cable is packaged to ensure protection during storage, transportation, and handling, while also facilitating easy identification and installation.
Spool Packaging
Most cables are wound onto wooden or plastic spools, which vary in size based on cable length and diameter. Smaller cables (≤10 mm diameter) are typically supplied on 50 m or 100 m plastic spools, lightweight and easy to carry by hand. Larger cables (≥16 mm diameter) are wound onto 250 m, 500 m, or 1000 m wooden spools, which are mounted on pallets for stability. Each spool is fitted with a cardboard or plastic flange to prevent the cable from slipping off during transport.
Protective Wrapping
The spooled cable is wrapped in stretch film to protect against dust, moisture, and physical damage. For outdoor storage, an additional layer of waterproof tarpaulin is applied. Each spool is labeled with a barcode, product code, conductor size, length, voltage rating, manufacturing date, and compliance certifications (e.g., CE, UL).
Bulk Packaging
For large-scale projects, cables may be supplied in bulk, coiled into drums with steel frames. These drums can hold up to 5000 m of cable and are equipped with lifting eyes for easy handling by cranes or forklifts.
