[Problem] Objects of the invention are to provide a cable assembly with reduced characteristic impedance at a protruding end portion of a first wire of a cable and configured for easy manufacture, and to provide a method for manufacturing the cable assembly.

[Configuration] A cable assembly A1 includes a terminal 400a, a cable 100, and an electroconductive member 200. The cable 100 includes an outer insulator 100, a shield conductor 120 inside the outer insulator 110, and at least one first wire 130a being a signal wire inside the shield conductor 120. The first wire 130a includes a protruding portion Pa protruding in the Y-Y′ direction from the shield conductor 120 and the outer insulator 110. The electroconductive member 200 is an electroconductive plate or electroconductive tape wound around at least a part in the Y-Y′ direction of the protruding portion Pa.

A skin effect heating system for long pipelines includes a heater cable disposed in a ferromagnetic or other conductive heat tube, the heater cable and heat tube cooperating to produce heat that is applied to the carrier pipe. The heater cable includes a conductor surrounded by an insulating layer, and then a semiconductive outer layer or “jacket.” The semiconductive jacket contacts the inner surface of the heat tube, where the charge density of the return current carried by the heat tube is at its highest. The semiconductive jacket material has a resistivity that is sufficiently low to reduce or eliminate arcing events such as corona discharge by allowing accumulated charge on the heat tube to dissipate. The resistivity is also high enough to prevent the return current from flowing into or through the semiconductive outer layer, so that heat production capacity of the system is maximized.

A composite cable includes a pair of first electric wires, a twisted pair wire formed by twisting a pair of second electric wires having a smaller outer diameter than the first electric wires, a tape member wound into a spiral around an assembly that is formed by twisting the pair of first electric wires and the twisted pair wire together, and a sheath covering an outer periphery of the tape member. The tape member and the sheath includes an inwardly projecting part formed in a spiral along a cable longitudinal direction and formed so as to enter inward at least one of a valley part between the two first electric wires and valley parts between the first electric wires and the twisted pair wire. The inwardly projecting part has a projecting length of not less than 3% of an outer diameter of the first electric wires.

A cable assembly extends in a longitudinal direction. The cable assembly comprises a first cable, two second cables, two coupling portions, an interposing portion and an outer cover. The first cable has a first conductor and a first cover. Each of the second cables has a second conductor and a second cover. The coupling portions couple the second covers, respectively, with the first cover. The first cable, the two second cables and the two coupling portions are arranged in a V-shape in a plane perpendicular to the longitudinal direction. The interposing portion extends along the first cable and the two second cables and has a full length which is equal to that of each of the first cable and the two second cables. The interposing portion is brought into contact with all the first cable and the two second cables.

The invention relates to a ringed tubular sheath which comprises a longitudinal strip which can be easily detached by a user, in particular manually. More specifically, the invention relates to a ringed tubular sheath comprising a sheath body (1) and a longitudinal strip (6) which are made of materials that substantially do not adhere to one another, the longitudinal strip (6) comprising, on each of its longitudinal sides, an upper projection (2, 8) and a lower projection (3, 9), between which a respective longitudinal edge (5, 7) of the sheath body (1) is fitted, this sheath being distinctive in that the longitudinal strip (6) is substantially in the shape of an arc of a ringed tube. The invention also relates to a manufacturing method and to the use of such a sheath.
