Submarine low loss cable system and method for arranging a submarine cable landfall system
20180158566 · 2018-06-07 ·

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.

Impedance matching device

An electrical cable includes a first wire conductor separated from a second wire conductor and a compensation area proximate to, but separated from, an end portion of the cable and a method of manufacturing such an electrical cable. The first and second wire conductors are each connected to a contact element. The first and second wire conductors are separated by a first distance within the compensation area. The first and second wire conductors are separated by a second distance outside of the compensation area. The first distance is less than the second distance, thereby decreasing an impedance of the cable within the compensation area.
