A cable includes a wire bundle composed of a plurality of wires bundled together; a binder tape spirally wound around an outer circumference of the wire bundle; a conductive tape having electrical conductivity and spirally wound around an outer circumference of the binder tape; and a sheath covering the binder tape and the conductive tape. The conductive tape is spirally wound around the outer circumference of the binder tape in such a manner that one end and an other end in a width direction do not overlap, and a spiral winding direction of the conductive tape and a spiral winding direction of the binder tape are opposite. A damage detection device for detecting damage to the cable is configured such that an electric current is applied to the conductive tape and the linear conductor and a damage detection signal indicating that damage has occurred to the cable is output when the electric current is inactive.

A wire includes a steel wire conductor and an insulation layer wrapped around the steel wire conductor. The steel wire conductor has a steel wire and a copper layer wrapped around the steel wire. The steel wire of the steel wire conductor has high strength and flexibility, and the copper layer of the steel wire conductor has high conductivity and current carrying capacity.

A combined cable includes at least two cable groups, each comprising at least one cable arranged side by side. Each cable group further comprises an adhesive layer wrapping a periphery of the at least one cable and having adhesion agent located on an outside of the adhesive layer. Each cable group further includes two coating layers, respectively adhered to a periphery of the adhesive layer of each cable group with the adhesion agent from upper and lower sides of the at least two cable groups. The coating layers located between adjacent two cable groups are detachably abutted together.

A rectangular cross-section multi-core insulated wire includes an assembly of wires in which insulating layers are formed on peripheries of conductors, and the assembly of the wires is a composite twisted structure, and includes first twisted wires formed by twisting the wires, second twisted wires formed by twisting the first twisted wires, and third twisted wires formed by twisting the second twisted wires. An insulating fiber thread is wound around a periphery, a cross-section is formed in a rectangular shape, and a winding direction of the fiber thread is a direction opposite to a twisting direction of outermost twisted wires in the assembly of the wires.

Disclosed is an armored cable assembly including a core having a notched assembly tape about a plurality of conductors. A metal sheath surrounds the core.
