Embodiment 1

[0016] Such as figure 1 As shown, the rotating core cable described in this embodiment includes an insulating sheath 30, and a rotating core is arranged in the insulating sheath 30; the rotating core is formed by rotating and twisting four conductive cores, so The conductive core is formed by a metal wire core 20 and a conductive layer 10 coated on the metal wire core. Preferably, the conductive layer is copper or copper alloy plating, nickel or nickel alloy plating.

[0017] Wherein, the insulating sheath is prepared by extruding the following raw materials in parts by weight; the raw materials are composed of 8-10 parts of tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, 35 -50 parts of MDI, 10-15 parts of polytetrahydrofuran ether glycol with a molecular weight of 800-1000, 15-20 parts of polybutylene adipate with a molecular weight of 1000-1200, 4-6 parts of 1,4- Butylene glycol, 1-2 parts of isophorone diamine, 2-3 parts of adipic acid, 3-5 parts by weight of zi...

Abstract

The invention relates to a cable with a rotary cable core. The cable with the cable core comprises an insulating protection sleeve, and the rotary cable core is formed by rotating and twisting four conducting cores, and the conducting cores are formed by metal cable core bodies and conducting layers wrapping the metal cable core bodies. Because the conducting layers are arranged on the metal cable core bodies, high anti-electromagnetic interference effect can be achieved; the insulating protection sleeve has good flexibility, deflation resisting performance and water blocking characteristics, and is excellent in acid resisting performance, alkali resisting performance, hydrolysis resisting performance and stability; the cable is high in electrical performance, and therefore the service life of the power cable is prolonged.

Description

technical field [0001] The invention belongs to the technical field of cable design and manufacture, and more specifically, the invention relates to a rotating core cable. Background technique [0002] With the continuous and rapid growth of my country's economy, it has provided a huge market prospect for the development of the cable industry. The strong temptation of the Chinese market has made the world focus on the Chinese market. In the short decades of reform and opening up, China The huge production capacity formed by the cable manufacturing industry has impressed the world. With the continuous expansion of industries such as electric power, communications, rail transit, automobiles, and shipbuilding, the demand for wires and cables is also growing rapidly. It can be predicted that the wires and cables industry will have huge development potential in the future. [0003] At present, the wire and cable industry is the second largest industry in China after the automobil...
