A wire harness including: a first conductive path; a second conductive path that is different from the first conductive path; and an exterior cover that covers the first conductive path and the second conductive path, wherein: the first conductive path includes a conductive first tubular conductor that is tubular in shape, the second conductive path includes a conductive second tubular conductor that is tubular in shape, and a thickness of the first tubular conductor is different from a thickness of the second tubular conductor.

A method for manufacturing a terminal-equipped electric wire includes a step of crimping a first terminal to one end of an electric wire, a step of crimping a second terminal to the other end of the electric wire with a tubular seal member, a first waterproofing step of providing, at the one end of the electric wire, an anticorrosion member that covers an element wire bundle of the electric wire, and a second waterproofing step of providing, at the other end of the electric wire, a sealing member so as to fill gaps between conductive element wires of the element wire bundle in a tubular insulating sheath. The second waterproofing step is performed after the first waterproofing step is performed.

A method for manufacturing a terminal-equipped electric wire includes a step of crimping a terminal to one end of an electric wire, a step of crimping another terminal to the other end of the electric wire, and a waterproofing step of providing a sealing member at the other end of the electric wire so as to fill gaps between conductive element wires of an element wire bundle. The waterproofing step includes, in this order, a step of applying a resin to the element wire bundle to block at least a part of an inner portion of a tubular insulating sheath, a step of waiting during curing of the resin or until the curing is completed, and a step of applying the moisture curable resin to the element wire bundle, blocking a remaining portion of the inner portion of the insulating sheath, and curing the resin.

A water blocking layer/sheathing for subsea power cables made from a CuNiSi-alloy.

A method can include extruding an electrically insulating elastomeric compound about a conductor where the electrically insulating elastomeric compound includes ethylene propylene diene monomer (M-class) rubber (EPDM) and an alkane-based peroxide that generates radicals that form decomposition products; cross-linking the EPDM via radical polymerization to form an electrically insulating layer about the conductor; heating the cross-linked EPDM to at least 55 degrees C. to reduce the concentration of the decomposition products in the electrically insulating layer; and disposing a gas barrier layer about the electrically insulating layer.
