Under Water Cable

Underwater Cable

Application

Under Water Cable is intended for power feeder and/or communication/control applications under water.It can be divided into waterproof cable for submersible pumps and submarine cables.Submersible cable is suitable for power connection of submersible motor of AC 50Hz, voltage 300/500V and below (one end of cable is in the water, the other is in the air)

Constructions

Conductor:Bare copper wire IEC 60228 Class 5/DIN VDE 0295 Class5

Insulation:Waterproof Rubber

Filler:Waterproof Rubber

Sheath:Waterproof Rubber.
