HVDC cable

Belongs to:
Underground and sea cables
Synonyms:
High-voltage direct-current cable
Description:

HVDC cables are high-voltage power transmission lines which transmit electric energy via high DC voltage over shorter distances from 10 to several 100 km length that are burried in the ground or seabed. Examples for HVDC sea cables in Europe are NordNed between Norway and the Netherlands as well as Baltc Calbe between Germany and Sweden.

Frequency ranges:
  • 0 Hz
Type of field:
electric and magnetic
