The materials used in PVC insulated flexible copper wires 1.5mm² and 2.5mm² (IEC 60227-5) are carefully selected to ensure optimal performance, flexibility, and safety. The combination of high-quality copper for the conductor and PVC for the insulation results in a wire that is both efficient and reliable.
The conductor is made from high-purity electrolytic copper, which is known for its excellent electrical conductivity. The
Copper Strands are annealed to enhance their flexibility, making the wire easy to bend and handle. Annealing involves heating the copper to a specific temperature and then allowing it to cool slowly, which reduces the hardness of the metal and increases its ductility. This process is crucial for ensuring that the
Stranded Conductor can withstand repeated bending without breaking.
The insulation layer is composed of a special grade of PVC that is formulated to provide good electrical insulation, mechanical strength, and resistance to heat, chemicals, and abrasion. The PVC is mixed with additives such as plasticizers, stabilizers, and antioxidants to improve its properties. Plasticizers increase the flexibility of the PVC, allowing the insulation to bend along with the conductor. Stabilizers protect the PVC from degradation due to heat and ultraviolet (UV) radiation, extending the wire's service life. Antioxidants prevent oxidation of the PVC, ensuring that it remains stable over time.
The style of these wires is characterized by their stranded conductor and smooth, uniform insulation. The stranded conductor consists of multiple small-diameter copper wires twisted together in a specific pattern, which gives the wire its flexibility. The number of strands varies between the 1.5mm² and 2.5mm² wires, as mentioned earlier, but the twisting pattern is designed to ensure that the strands work together to carry current evenly.
The insulation is extruded over the stranded conductor in a continuous process, resulting in a smooth, seamless coating that adheres tightly to the conductor. This ensures that there are no gaps or voids in the insulation, which could lead to electrical leakage. The insulation is available in a range of colors, including white, black, gray, red, and blue, which helps in identifying different circuits and phases in electrical installations. This color-coding is essential for ensuring safe and efficient wiring, as it allows electricians to easily distinguish between live, neutral, and
Earth Wires.

The production process of PVC insulated flexible copper wires 1.5mm² and 2.5mm² (IEC 60227-5) involves several stages, each of which is carefully controlled to ensure the quality and consistency of the final product. The process starts with the preparation of the copper conductor and ends with the testing and packaging of the finished wire.
The first stage is the production of the copper strands. High-purity copper rods are drawn through a series of dies to reduce their diameter to the required size for the individual strands. This drawing process is done in multiple passes, with each pass reducing the diameter slightly. After drawing, the strands are annealed in a furnace to soften them and improve their flexibility. The annealing temperature and time are carefully controlled to achieve the desired mechanical properties.
Once the individual strands are prepared, they are twisted together to form the stranded conductor. The twisting process is carried out using a stranding machine, which twists the strands in a specific direction and lay length to ensure a tight and uniform bundle. For the 1.5mm² wire, 19 strands are twisted together, while the 2.5mm² wire uses 49 strands. The twisting process ensures that the conductor is flexible and that the current is distributed evenly among the strands.
Next, the stranded conductor is fed into an extrusion machine, where the
PVC Insulation is applied. The PVC material is first melted and mixed with additives in a hopper, then forced through a die that shapes the insulation around the conductor. The extrusion process is continuous, and the speed of the conductor and the extrusion rate are carefully synchronized to ensure a uniform insulation thickness. The temperature of the extrusion process is also controlled to ensure that the PVC adheres properly to the conductor and forms a smooth coating.
After extrusion, the
Insulated Wire is cooled in a water bath to solidify the PVC insulation. The cooling process is important to maintain the shape and dimensions of the insulation. Once cooled, the wire is passed through a series of gauges to check the insulation thickness and overall diameter, ensuring that they meet the specified requirements.
The next stage is testing the wire to ensure it complies with IEC 60227-5. Various tests are conducted, including electrical tests such as insulation resistance and voltage withstand tests, and mechanical tests such as tensile strength, elongation, and bending tests. The voltage withstand test involves applying a high voltage (typically 1500V AC) to the wire for a specified period (usually 5 minutes) to ensure that the insulation does not break down. The insulation resistance test measures the resistance of the insulation to the flow of leakage current, ensuring that it is sufficient to prevent electrical hazards.
Once the wire passes all tests, it is wound onto reels or spools of specified lengths, typically 100 meters or 500 meters. The reels are then labeled with information such as the wire specification, length, voltage rating, and compliance with IEC 60227-5. Finally, the reels are packaged to protect them during transportation and storage.
The packaging of PVC insulated flexible copper wires 1.5mm² and 2.5mm² (IEC 60227-5) is designed to protect the product during transportation, storage, and handling, while also providing clear and useful information to the user.

For both 1.5mm² and 2.5mm² wires, the most common packaging form is reels or spools. The reels are typically made of high-quality cardboard or plastic, which are lightweight yet strong enough to withstand the weight of the wire. The size of the reel depends on the length of the wire; 100-meter lengths are usually wound onto smaller reels with a diameter of around 20cm, while 500-meter lengths are on larger reels with a diameter of approximately 30cm. The reels are designed with a central core that allows for easy mounting on wire dispensers during installation, facilitating smooth unwinding of the wire without tangling.
The surface of the reel is printed with essential information about the product, including the wire specification (1.5mm² or 2.5mm²), length, voltage rating (450/750V), compliance with IEC 60227-5, manufacturer's name and logo, batch number, and production date. This information is crucial for users to identify the correct wire for their application and to trace the product if necessary.
In addition to the reel, the wire is often wrapped in a protective plastic film to prevent dust, moisture, and damage to the insulation during storage and transportation. The plastic film is transparent, allowing users to inspect the wire's condition without opening the packaging. For larger orders or bulk shipments, multiple reels may be packed into a cardboard box or wooden crate, which provides additional protection and makes handling easier. The boxes or crates are labeled with the same information as the reels, along with the total number of reels and the total length of wire inside.
The packaging is also designed to be environmentally friendly, with most materials being recyclable. Cardboard reels and boxes can be recycled, while plastic reels are often made from recycled materials and are themselves recyclable. This aligns with the growing trend towards sustainable packaging in the industry.
