Description

Technical Field

[0001] The utility model relates to the technical field of electric wires, in particular to a flat cloth electric wire. Background Art

[0002] Cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple wires and insulation layers, and are used to connect circuits, electrical appliances, etc.

[0003] The existing announcement number CN216435487U adopts a polyvinyl chloride butadiene nitrile composite material outer sheath flat pressure-proof cable, including an outer sheath, an inner sheath and a wire assembly, the outer sheath, the inner sheath and the wire assembly are arranged from the outside to the inside in sequence, the number of the wire assemblies is four, and the outer surface of the outer sheath is glued with an outer insulating layer; it arranges multiple groups of wire assemblies flatly to form a flat shape on the outside, thereby improving the overall compressive mechanical properties, the outer insulating layer isolates the external power supply, and the waterproof layer can effectively prevent rainwater from penetrating into the inside. The polyvinyl chloride butadiene nitrile composite material outer sheath flat pressure-proof cable adopts a flat shape, so that the overall compressive performance is improved and the protective performance is good. However, the existing flat cables have poor tensile and tearing resistance, and relatively poor oil resistance. For this reason, we propose a flat cloth wire. Utility Model Content
