Description

Conductor: Conductor cross section of 800mm2 or below is stranded through compacting round core, with better roundness and higher compacting coefficient. Conductor cross section more than 800mm2 is made by segment of Milliken method to minimize skin connecting and alternating current impedance and increase power transmission capacity of cable.

Insulation: XLPE, gravity feeding in 1000 level ultra-clean environment.

Product line: VCV/CCV
