EHV Cable

Extra-High Voltage DC Cables

The extra-high voltage DC cables (HVDC) convert AC power into DC power before transmission. Since they have low transmission loss and can transmit more than twice the current, they are suitable for long-distance large-capacity transmission.
Taihan has developed HVDC 500kV MI cables insulated with polypropylene laminated paper (PPLP) and HVDC 500kV XLPE cables insulated with cross-linked polyethylene (XLPE) according to the insulation method required by the consumer.

Types
  • HVDC 500kV MI cable: Impregnated with insulating oil after paper-rolling process.
    (General OF cables are filled with insulating oil in the metallic sheath)
  • HVDC 500kV XLPE cable: Insulated with DC-XLPE material
Features
  • Increased importance of long-distance transmission
  • Available for land use in addition to submarine cables
  • Lots of advantages such as high transmission capacity, long distance connection, low cost, low loss, etc.
