Power cable HEAY31

waterprooffor marine applications

Submarine power cables are special ones which transmit electric power from land to oil plantforms of islands and islets or between oil plantforms. This kind of products mainly possess such good characteristics as corrosion -resistance,water-proof performany and can run in seawater for a long time and then have enough mechanical strength to load laying tension and seawather's impact. Execulting standard is enterprise standard Q/02hdl011. The products have superior water-proof property. Max.working temperature in normal operation is 90℃.Max.working temperature in short circuit doesn't exceed 250℃(Time doesn't exceed 5s in short circuit).
