Plant for transmitting electric power
First Claim
1. A plant for transmitting electric power between at least two alternating voltage networks, each connected through a station to a direct voltage network for high voltage direct current, each station being adapted to transmit electric power between the direct voltage network and the respective alternating voltage network, said plant comprising:
- at least one voltage-stiff VSC converter in each station adapted to convert direct voltage to alternating voltage and the alternating voltage to direct voltage, wherein said electric power is fed in both directions in said direct voltage network between the stations; and
at least one cable with an insulating layer of polymer base surrounding a conductor, said cable forming the direct voltage network connecting the stations.

Abstract
A plant for transmitting electric power between at least two alternating voltage networks which are each connected through a station to a direct voltage network for high voltage direct current. The stations transmit power between the direct voltage network and the respective alternating voltage networks. At least one VSC converter is in each station to convert direct voltage to alternating voltage and the converse. A cable with an insulating layer of polymer base surrounding a conductor forms the direct voltage network connecting the stations.
