This drawing process is done with great precision to ensure the conductor has a uniform diameter and smooth surface. After drawing, the copper conductor undergoes annealing treatment. It is heated to a temperature of around 400-600°C and then slowly cooled. This annealing process removes internal stresses in the copper, improving its ductility and conductivity, making it easier to handle during installation.

Next, the insulation layer is applied to the copper conductor through an extrusion process. The PVC material, in the form of pellets, is fed into an extruder where it is melted. The molten PVC is then extruded onto the surface of the copper conductor, forming a uniform insulation layer. The extrusion process is carefully controlled to ensure the insulation layer has the correct thickness and adheres tightly to the conductor. The temperature, pressure, and speed of the extruder are all monitored and adjusted to achieve the desired results. During extrusion, color masterbatches may be added to the PVC material to give the insulation layer the desired color, allowing for easy identification of different types of cables.

After extrusion, the cable is cooled in a water bath to solidify the PVC insulation layer. This cooling process ensures that the insulation layer maintains its shape and properties. The cooled cable is then pulled through a series of rollers to straighten it and ensure uniform dimensions.

Once the insulation layer is applied and cooled, the cable undergoes a series of quality inspections. These inspections include checking the diameter of the conductor and the thickness of the insulation layer to ensure they meet the specified standards. The insulation resistance and withstand voltage of the cable are also tested to verify its insulation performance. Additionally, the cable is subjected to flame retardancy tests to ensure it complies with UL94 V-0 standards.
