Multi-core anti-electromagnetic interference control cable

Abstract

The invention discloses a multi-core anti-electromagnetic interference control cable, which belongs to an anti-electromagnetic interference control cable and mainly solves the technical problems that the conventional cable has poor anti-electromagnetic interference performance, is easily disturbed by an electromagnetic field and the like. The technical scheme of the invention has the key points that: more than one layer of cable core consisting of more than three anti-electromagnetic wires is arranged around the anti-electromagnetic wires 1 by using a single-core anti-electromagnetic wire as a center; and the outer layer of the cable core is provided with an aluminum-plastic composite film lapped shielding layer, a tinned copper wire woven shielding layer and an environment-friendly low-smoke halogen-free flame-retardant polyolefin elastomer jacket in turn from the inside to the outside. The cable has the functions of anti-electromagnetic interference, environmental protection, flame resistance, abrasion resistance, water prevention, weather resistance, ageing resistance, mould resistance and the like, and can meet the requirement of synchronous transmission of power and signals under a strong magnetic field environment, particularly meet the requirement of a large-sized power plant or a large-sized data switching system and also meet the using requirements of ships and rapid trains for reliability, long service life, small volume and light weight.

Description

technical field

[0001] The invention relates to a wire and cable. In particular, it is an anti-electromagnetic interference control cable that can be used in an electrical appliance control system in a strong magnetic field environment. Background technique

[0002] With the rapid development of the electric power (including wind power) industry and the manufacturing industry of ships and high-speed trains, the requirements for the configuration of cables for electrical equipment used in ships and high-speed trains are also increasing. Due to the particularity of the operating environment of ships and high-speed trains, in a strong magnetic field environment, cables are required to have high reliability, long life, small size, light weight, and excellent flame retardancy, wear resistance, waterproof, weather resistance, and aging resistance , mold resistance and excellent electrical properties. The existing cables for ships have poor anti-electromagnetic interference perfo...
