A self-supporting electric power cable is disclosed. The electric power cable includes an outer jacket portion and a core portion. The core portion includes at least one insulated conductor and at least one supporting cord. The at least one insulated conductor includes a number of individual wires, and the at least one supporting cord includes synthetic fibres. The number of individual wires, individually or arranged in bundles, are arranged in a first lay direction. The at least one insulated conductor and the at least one supporting cord are arranged in a second lay direction. The at least one supporting cord is arranged as a separate unit in a cross sectional sector of the self-supporting electric power cable. Thus flexible and durable power cable for sea use is provided. Also an offshore arrangement is disclosed herein.

A cable having a multipurpose space area comprises pods formed at both side ends of a cable and accommodating support members; electric cable insertion portions formed at the center of the cable between the pods and accommodating electric cables; support members inserted into the pods; and multiple electric cables inserted into the electric cable insertion portions. The electric cable insertion portion is partitioned into a plurality of areas by a plurality of joining portions and fusion portions to which fusible materials fused by heat are applied are formed at inner sides of the respective areas of the electric cable insertion portion.

A cable core for a cable, in particular, for an induction cable that includes multiple such cable cores which have a conductor that is interrupted in the longitudinal direction at specified longitudinal positions at multiple separation points, thereby forming two conductor ends. An insulating intermediate piece is provided for connecting the conductor ends, and the conductor ends are arranged on both sides of the intermediate piece. The conductor and the intermediate piece are surrounded together by a continuous insulating jacket in order to form the cable core. In a preferred concept, a respective intermediate piece is arranged between the two conductor ends by two adapter elements. In another preferred concept, a respective intermediate piece, in particular, a ceramic intermediate piece, is connected directly to two conductor ends. A cable is formed from a plurality of such cable cores.

Provided is a cable having a multipurpose space area, and particularly, a cable having a multipurpose space area, including: pods (11) formed at both side ends of a cable and accommodating support members; electric cable insertion portions (12) formed at the center of the cable between the pods (11) and accommodating electric cables; support members (20); multiple electric cables (30); and the clamp (40) including an upper clamp (41) in which upper insertion grooves (41a) installed above the support members (20) and having upper insertion grooves (41a) formed at portions of both side ends of inner surfaces thereof in a longitudinal direction of the clamp and upper suspension projections (41b) formed at locations opposite to the pod at an end of one end or the pods at both ends and a lower clamp (42) installed below the support member (20) and having lower insertion portions (42a) formed at portions of both side ends of the inner surfaces thereof in the longitudinal direction of the clamp and lower suspension projections (42b) formed at locations opposite to the pod at an end of one end or the pods at both ends, and the upper clamp (41), the support members (20), and the lower clamp (42) are screw-joined by a bolt (B) consecutively penetrating the upper clamp (41), the support members (20), and the lower clamp (42) and the electric cable insertion portion (12) is partitioned into a plurality of areas by a plurality of joining portions (13) and fusion portions (14) to which fusible materials fused by heat are applied are formed at inner sides of the respective areas of the electric cable insertion portion to facilitate bending and straight posture of an electric cable and prevent entanglement and twisting of the electric cable and strengthen joining force between the clamp and the support member.

A method for manufacturing a multi-core cable including an inclusion, a plurality of electric wires twisted around the inclusion in a state that tension is applied to the inclusion, a shield portion provided around the electric wires, and a sheath is provided. The method includes a preparation step of preparing the inclusion having a diameter exceeding a predetermined diameter on assumption that tension is applied to the inclusion and the diameter is reduced to the predetermined diameter, a twisting step of twisting the electric wires while applying tension to the inclusion using the inclusion prepared in the preparation step as the central member, an inner wire manufacturing step of manufacturing an inner wire portion by providing the shield portion around the electric wires twisted by the twisting step, and an extrusion step of extrusion-molding a sheath to the inner wire portion manufactured in the inner wire manufacturing step.

A pre-assembled low voltage wiring harness is configured for being installed in a building having framing. The wiring harness includes an exterior sheath having a trunk portion and a plurality of branch portions extending off the trunk portion. The wiring harness further includes a plurality of low voltage cables bundled inside the exterior sheath, and a plurality of attachment members coupled to the exterior sheath at a respective plurality of fixed, predetermined locations along a length of the exterior sheath. Each one of the attachment members includes a flexible strap, an attachment connector configured for removably attaching to the framing of the building, and an attachment marker for indicating an intended attachment location. The attachment connector may be a carabiner, a soft shackle, a hook, a snap hook, a clip, or a similar connector that does not require any tools for installation so that the wiring harness is easily installed.

An electric vehicle (EV) charging cable for charging electric vehicles is described. The EV charging cable includes power conductors, a ground conductor, and a signal conductor. The EV charging cable further includes hard metal cordages within the EV charging cable and cut resistant plastic cordages that are positioned about the hard metal cordages respectively. The EV charging cable further includes a cable jacket that surrounds the interior components of the cable.
