摘要:
A low loss cable system adapted for use as a cable landfall system. The cable system comprises a cable having a plurality of cores. Each core comprises a conductor, a first insulating layer, a second electrically conductive layer and a third layer. The cable comprises two sections, connected at a connection point CP. A first section of the cable is arranged to be exposed to a landfall area and a second section of the cable is arranged to be exposed to a submarine area.
The cable is arranged such that circulating currents are prevented or reduced in the second conductive layers of the cable in the section exposed to the landfall area, thus assisting in maintaining the ampacity of the cable in this section without, or by reducing, the need to increase the cross sectional area of the cable in the landfall area. This is accomplished by electrically connecting the second conductive layers of the cores to each other at the connection point. At a distal end of the first section of the cable, the second layers are arranged to leave an open ended termination, thus avoiding a closed circuit that would otherwise create circulating currents in the second layers of the first section, thus maintaining ampacity.
