220 kV underground cable

Belongs to:
Underground and sea cables
Description:

220 kV underground cables are primarily used in Germany, Austria or Switzerland for the transmission of energy or information over short distances. In America, Africa or Asia, where the transmissions paths are several hundred km long, 220 kV are not advisable due to their high idle power.

Frequency ranges:
  • 50 Hz
Type of field:
magnetic
