The solid
Copper PVC Insulated Wire comes in two distinct specifications: 1×1.5mm² and 1×2.5mm², both designed to operate within the 300/500V voltage range and fully compliant with the IEC 60227 standard. These specifications are not arbitrary but are carefully engineered to meet the diverse needs of various electrical applications.
For the 1×1.5mm² wire, the conductor cross-sectional area is precisely 1.5 square millimeters. This measurement is critical as it directly influences the current-carrying capacity of the wire. The conductor, being solid copper, has a diameter that corresponds to this cross-sectional area, ensuring optimal electrical performance. The insulation layer, made of high-quality PVC, adds to the overall diameter of the wire. The thickness of the
PVC Insulation is carefully calibrated to provide sufficient protection while keeping the wire flexible enough for easy installation.
The 1×2.5mm² wire, with a larger cross-sectional area of 2.5 square millimeters, naturally has a greater current-carrying capacity compared to the 1×1.5mm² variant. Its solid
Copper Conductor is thicker, and the PVC insulation layer is also adjusted accordingly to maintain the necessary insulation properties and mechanical strength.
Both wires adhere to the 300/500V voltage rating, where 300V is the rated voltage for the wire when insulated from the ground, and 500V is the rated voltage for line-to-line operation. This voltage range makes them suitable for low-voltage electrical systems, which are commonly found in residential, commercial, and light industrial settings.
In terms of electrical conductivity, the high-purity solid
Copper Conductors ensure excellent performance. Copper is known for its low electrical resistance, which means less energy loss during current transmission. This not only improves the efficiency of the electrical system but also reduces the risk of overheating, which is crucial for safety.
The insulation resistance of the PVC layer is another important parameter. It measures the ability of the insulation to resist the flow of leakage current. A high insulation resistance indicates that the insulation is effective in preventing current from leaking to the surrounding environment, thus minimizing the risk of electric shock and short circuits.
Mechanical parameters such as tensile strength and elongation at break are also significant. The solid copper conductor has high tensile strength, allowing it to withstand the stresses encountered during installation, such as pulling and bending. The PVC insulation layer also has good tensile strength and
Flexibility, ensuring that it doesn't crack or break easily under normal handling and installation conditions. The elongation at break indicates how much the material can stretch before breaking, which is important for withstanding the mechanical forces during installation and use.
The solid
Copper PVC Insulated Wire (1×1.5mm² & 1×2.5mm²) 300/500V (IEC 60227 Compliant) finds its application in a wide range of scenarios due to its unique combination of properties.
In residential buildings, these wires are extensively used for indoor wiring. The 1×1.5mm² wire is ideal for lighting circuits. Lighting fixtures typically draw relatively low currents, and this wire's current-carrying capacity is sufficient to handle the load of multiple light bulbs, switches, and related accessories. It can be easily routed through walls, ceilings, and floors, making it suitable for both new construction and renovation projects.
The 1×2.5mm² wire, with its higher current-carrying capacity, is commonly used for power outlets in residential settings.

The choice of materials for the solid copper PVC insulated wire is crucial to its performance, durability, and safety.
The conductor is made of high-purity solid copper. The high purity of the copper ensures excellent electrical conductivity, as impurities can increase electrical resistance and reduce the efficiency of current transmission. Solid copper is preferred over stranded copper in certain applications because it provides better mechanical strength and is less prone to fatigue from vibration. It also has a more consistent electrical performance, which is important for maintaining stable current flow.
The copper conductor undergoes a series of treatments to enhance its properties. One such treatment is annealing, which involves heating the copper to a specific temperature and then cooling it slowly. This process makes the copper more ductile, allowing it to be bent and shaped easily during installation without breaking. It also relieves internal stresses in the copper, improving its overall mechanical stability.
The insulation layer is made of polyvinyl chloride (PVC), a synthetic polymer that offers a range of beneficial properties. PVC is an excellent insulator, with high dielectric strength, which means it can withstand high voltages without allowing current to pass through. This is essential for preventing electrical shocks and short circuits.
PVC is also resistant to a wide range of chemicals, including oils, acids, and alkalis, which makes the wire suitable for use in environments where exposure to such substances is possible. It has good flame-retardant properties, meaning it is less likely to catch fire and, if it does, it burns slowly and releases less smoke compared to some other
Insulation Materials. This enhances the safety of the wire in case of a fire.
In terms of style, the wire has a simple and functional design. It is a single-core wire, meaning it consists of a single solid copper conductor surrounded by a PVC insulation layer. This simplicity makes it easy to handle and install. The insulation layer is typically colored, with different colors indicating different purposes. For example, red or brown is often used for live wires, blue or black for neutral wires, and green or yellow with green stripes for
Earth Wires. This color-coding helps electricians identify the correct wire for each connection, reducing the risk of errors during installation.
The surface of the PVC insulation is smooth, which allows the wire to be pulled through conduits and other tight spaces with ease. It also has a certain degree of flexibility, making it suitable for bending around corners and obstacles during installation. The overall diameter of the wire is designed to be compatible with standard electrical fittings and accessories, ensuring a secure and reliable connection.
The production of the solid copper PVC insulated wire involves a series of precise and controlled steps to ensure the final product meets the required specifications and quality standards.
The first step is the selection and preparation of the copper raw material. High-purity copper rods are chosen as the starting material. These rods are inspected for purity and quality to ensure they meet the necessary standards. The copper rods are then drawn through a series of dies to reduce their diameter and form the solid copper conductor of the desired size (1.5mm² or 2.5mm²). This drawing process, known as wire drawing, not only reduces the diameter but also increases the strength and hardness of the copper through work hardening. After drawing, the copper conductor may undergo annealing to improve its ductility, as mentioned earlier.
Next, the copper conductor is cleaned to remove any dirt, oil, or oxide layers that may have formed during the drawing process. This cleaning is essential to ensure good adhesion between the conductor and the insulation layer. Various cleaning methods, such as chemical cleaning or ultrasonic cleaning, may be used depending on the specific requirements.
The insulation extrusion process is the next critical step. The cleaned copper conductor is fed into an extrusion machine, where molten PVC is extruded around it to form the insulation layer. The extrusion machine is equipped with a die that shapes the PVC into the desired thickness and diameter around the conductor. The temperature, pressure, and speed of the extrusion process are carefully controlled to ensure uniform thickness of the insulation layer and proper adhesion to the conductor.
After extrusion, the insulated wire is cooled to solidify the PVC insulation. Cooling is typically done using water or air, and the cooling rate is controlled to prevent thermal stress in the insulation layer, which could lead to cracks or other defects.
Once cooled, the wire undergoes a series of quality checks. These checks include measuring the diameter of the conductor and the insulation layer to ensure they meet the specified dimensions. The electrical properties, such as insulation resistance and conductivity, are also tested using specialized equipment. Mechanical properties like tensile strength and elongation at break are evaluated through sample testing.
If the wire passes all the quality checks, it is then spooled onto reels or coils of various sizes for packaging. The spooling process is done carefully to avoid damaging the wire or causing tangles. The reels or coils are labeled with important information such as the wire specification, voltage rating, length, batch number, and compliance with IEC 60227.
Throughout the production process, strict quality control measures are implemented. Each batch of raw materials is tested for quality, and in-process inspections are carried out at various stages to identify and rectify any defects early on. This ensures that the final product is consistent in quality and meets all the required standards and specifications.
The packaging of the solid copper PVC insulated wire is designed to protect the product during storage, transportation, and handling, while also providing clear and useful information to the customer.
