64/110kV (127/220kV) SUBMARINE CABLE

Characteristics

HV submarine power cable is specially developed for long distance transmission.

To lower CO2 emission, green energy has been developed fast, in Asia and Europe, offshore wind mill has created huge demand and development of HV submarine cable, both HVAC and HVDC.

For HVAC has equipped a tower with 2VCV lines for XLPE extrusion, a vertical turntable lay-up machine, multiple in-house turntable for semi-finished core, big outside turntable for finished cable, movable factory joint room, movable degassing tent, all in all, is specially for 3 phase HV AC cable. Now we can produce up to 500kV.
