PVC insulation provides good electrical insulation, effectively isolating current and preventing current leakage and arcing. It has high insulation resistance and dielectric strength and can be used for low to medium voltage electrical equipment and lines.

PVC material has good corrosion resistance, can resist some chemicals and corrosive environment erosion, so as to extend the service life of the line.

PVC materials are flexible and easy to work with, allowing for easy cutting and termination. This makes PVC insulated un-sheathed solid copper wires easier to install with customized lengths and terminations as needed.

PVC insulated unjacketed solid copper wire is relatively low cost compared to other insulation materials and is easy to produce and supply. This makes it widely used in many low-cost applications such as home wiring, building electrics, small appliances, etc.


Solid copper wire has high mechanical strength and abrasion resistance and is able to withstand certain tensile forces and physical impacts. This makes PVC insulated unjacketed solid copper wire suitable for applications requiring high mechanical strength, such as indoor wires and cables.

PVC materials are often flame retardant, which inhibits the spread of flame and combustion, improving the safety of the wiring.

Despite the above advantages of PVC insulated unjacketed solid copper wire, there are some potential limitations to be aware of. For example, in high temperature environments, the PVC material may soften or melt, resulting in a loss of insulation performance. In addition, PVC is a non-environmentally friendly material, and there are environmental pollution and sustainability considerations.

While PVC-insulated unjacketed solid copper wire is widely used in many applications, in some special cases, such as in environments with high temperatures, high humidity, or the presence of chemical corrosives, other insulation materials or jacketing may need to be considered to meet specific requirements. In these cases, special insulating materials with higher temperature resistance, corrosion resistance or flame retardant properties may be selected.
