A refractory shield cable for computer control

Abstract

The invention relates to a refractory shield cable for computer control. The cable includes a cable assembly, A cable core is arranged in the inner cavity of the cable assembly, A metal conductor is arranged at that center of the wire core, A tape clad layer is arranged on that outside of the metal conductor, A phase separation shield layer is bonded on the outer side of the cladding layer throughan adhesive, At that outside of the phase-separated shield lay, an insulating ribbon is bonded by an adhesive, A fill layer is arranged on the outside of the cable assembly, A cladding layer is arranged on the outer side of the filling layer, A shield layer is adhered to that outside of the cladding layer through an adhesive, At that outer side of the shield layer, a fireproof filling layer is bonded with an adhesive, A reinforcing layer is bonded on the outside of the fireproof filling layer through an adhesive, and an abrasion-resistant layer is bonded on the outside of the reinforcing layer through an adhesive. The electric conductive unit runs most stably and reliably and has the most ideal use effect through the coordinated use of the layers, so that the overall fireproof performanceand the shielding performance of the cable are good, the overall strength is high, and the overall service life of the product is long and the safety is high.

Description

technical field [0001] The invention relates to a fire-resistant shielded cable for computer control, which belongs to the technical field of computer cables. Background technique [0002] Computer control cables usually use good electric conductors as shielding materials, which have obvious anti-interference effect on high-frequency signals, but for some low-frequency and strong electromagnetic field interference areas, ordinary computer control cables are no longer competent for normal signal transmission and anti-interference The high requirements of high requirements will often cause some signal distortions, which will lead to equipment malfunction and major accidents in severe cases; therefore, it is necessary to design a new structure for the computer control cable structure and materials, so that the computer control cable can operate in high and low frequency bands, It has strong anti-interference performance in the environment of high-intensity electromagnetic field...
