(6) PVC insulated and sheathed power cable (referred to as plastic cable or plastic cable), 1KV and 6KV poles, the main advantage is the manufacturing process is simple, no laying height difference, light weight, bending performance, Simple, resistant . PVC cables are generally known for their versatility, high tensile strength, and impeccable flexibility. Disadvantages of single core cable: These cables cannot be armor protected, so are unsuitable for applications where there is risk of mechanical stress Because of lack of armour, single core cable is more exposed to damage from external forces For applications needing cables to be installed in harsh conditions, armoured cables are preferred.
