Title:
SYSTEM FOR TRANSMISSION OF ELECTRIC POWER
Document Type and Number:
WIPO Patent Application WO2005045853
Kind Code:
B1
Abstract:
The invention concerns a high voltage transmission wire or cable for transmitting AC or DC power between two points. Preferably at least one point is connected to one or more power networks. The conductor of the wire or cable comprises a semiconducting outer layer (10) including distributed magnetic particles. Other embodiments include an insulation layer (12) including distributed magnetic material, micro-particles, ribbons tapes etc, and an insulation screen. The invention increases the distance over which power may be transmitted and/or eliminates the necessity for power compensation reactors partially or totally. This is achieved by increasing inductance and reducing AC capacitance leakage currents in AC lines and, when operated as a DC line, by reducing high frequency harmonics.
