  • Three-phase high voltage cable arrangement having cross-bonded cable screens and cross-bonded water sensing wires
    Patent number: 6872890
    Abstract: A cable arrangement where three cables have at least two cross-bonding locations when transmitting power between a first location and a second location. At the cross-bonding location not only the screens but also the water sensing wires are cross-bonded in cross-bonding devices. Thus, voltage differences between the water sensing wires and the screens of the respective cables in the three-phase system can be avoided. A particular application is found in high power transmission systems using high voltage cables.
