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.

A power cable includes a conductor; an insulator; an inner shield layer; an inner corrosion-proof layer; an outer shield layer; and an outer corrosion-proof layer, provided from center toward outside, wherein only the inner shield layer among the inner shield layer and the outer shield layer is directly grounded at one end of the power cable in an axial direction, and wherein only the outer shield layer among the inner shield layer and the outer shield layer is directly grounded at the other end of the power cable in the axial direction.

A coaxial three-phase servo motor power cable is comprised of a shielded twisted triple cable which transmits three phase electrical power from a servo amplifier to a servo motor, with the shield being electrically insulated and mechanically floating within an air void that exists inside a conduit having a diameter much greater than the shielded twisted triple cable. The conduit is covered by a braid shield, which is covered by shrink tubing which may be overlaid by one or more additional signal wires, with this entire assembly being further covered by an over braid shield, which is covered by an outer insulating sheath. Both the conduit braid shield and over braid shield are electrically terminated to back shells at each end of a cable assembly.
