The nylon sheathed cable has more excellences in physical and electrical performance than the PVC cable.
The cable has smaller outer diameter, lighter weight, less static friction coefficient than the same size of PVC cable, which greatly improve safety and convenience in installation and assembly of the cable.
It is self-lubrication, and has good resistance to corrosion, oil, acids, alkai, and moisture.
The cable is widely used on fixed installation, home appliance, lighting equipment, construction and aviation engine room with voltage of 450/750V.
