An electrical cable assembly, comprising a first electrical circuit further comprising a first plurality of insulated conductors longitudinally disposed to one another, wherein the first plurality of insulated conductors are cabled together in a bundle. The electrical cable assembly further comprises a second electrical circuit longitudinally disposed to the first electrical circuit, the second electrical circuit comprising a second plurality of insulated conductors longitudinally disposed to one another and cabled together in a bundle and a nonmetallic jacket surrounding the second plurality of insulated conductors and wherein the nonmetallic jacket isolating the first electrical circuit from the second electrical circuit. The electrical cable assembly further comprises a flexible interlocking metallic armor encasing the first and second electrical circuits.

An insulated wire capable of changing color when overheated under a current load includes an insulated core, at least one thermochromic strip, and a transparent plastic protective layer. The thermochromic strip is wound and fixed on the peripheral surface of the insulated core. The transparent plastic protective layer clads the peripheral surface of the insulated core and/or the top surface of the thermochromic strip. When the insulated core is overloaded and generates heat, the heat is transmitted to, and thereby changes the color of, the thermochromic strip. The color change is visible through the transparent plastic protective layer and can therefore alert the wire user in real time that the load on the insulated wire should be lowered.

Disclosed is a device for applying marking tubes onto cables including: a driving mechanism for a cable along a driving axis; at least one buffer pipe in a producing position aligned with the driving axis, the buffer pipe having dimensions adapted both for a cable to be marked to run through the buffer pipe and for a number of marking tubes to be threaded onto the buffer pipe; a pushing unit engaging and pushing along the driving axis at least one first out marking tube of the marking tubes threaded on the buffer pipe until this first out marking tube exits the buffer pipe and is released onto the cable. Also disclosed is a method for applying marking tubes onto cables using a buffer pipe. The cable is always driven in the same forward direction and there is no limitation of cable length or marking tube number or location.

A method of coiling a superconducting cable, where the superconducting cable is comprised of a plurality of stacked superconducting tapes, where the superconducting cable has a clocking feature that identifies an orientation of the superconducting tapes, the method comprising the step of orienting coils of the superconducting cable, such that a magnetic field from surrounding coils impinge upon a given coil at a desired angle, based upon an orientation of the clocking feature.

A method for determining the length of a line involves determining a length of a first electrical line, determining an identifier of the first electrical line, determining a length of a second electrical line, which is intended for installation in an electrical installation assembly, based on the length of the first electrical line and a starting length determined by means of the identifier.

A multi-conductor cable for a vehicle includes core wires respectively having a conductor formed by a plurality of twisted wires, and an insulating layer covering an outer periphery of the conductor, and a sheath layer disposed around the core wires. A marking portion is partially formed on an outer peripheral surface of the sheath layer, and a ratio of an arithmetic average roughness Ra2 of a peripheral region adjacent to the marking portion, with respect to an arithmetic average roughness Ra1 of the marking portion, at the outer peripheral surface, is 0.10 or greater and 0.90 or less.

Twisted pair communication cables that include reduced or minimal use of colorant may include a plurality of twisted pairs of individually insulated conductors, and the respective insulation formed around each conductor included in the plurality of twisted pairs may not be blended or compounded with any colorant. Physical indicia may be selectively formed on respective outer surfaces of the insulation of at least two of the plurality of twisted pairs. The physical indicia may include colorant that occupies less than 5.0% of a surface area of the insulation on which it is formed, and the physical indicia facilitate identification of the plurality of twisted pairs. A jacket may formed around the plurality of twisted pairs.
