IEC 60502-1 PVC Sheathed Armored Copper Cable For Power Grids
PVC sheathed power cable:
Polyvinyl chloride insulated power cables not only have high mechanical strength, good environmental stress resistance, good electrical properties and chemical corrosion resistance, but also have a simple structure, light weight and easy use. It is suitable for transmission and distribution lines with AC rated voltage U0/U up to 0.6/1kV.
The main feature of flame-retardant PVC power cables is that they are not easy to catch fire, or the continuous burning of the cable is very limited during fire. It is suitable for places where multiple cables are closely laid, such as power stations, subways, tunnels, high-rise buildings, large factories, mines, oil fields, and coal mines.
