Problems solved by technology

[0004] Control cables are used to transmit control electrical signals. The existing control cables are mainly composed of core wires, insulating layers, shielding layers and sheaths. Shielding layer, the function of the shielding layer is to avoid the influence of the external electromagnetic field on the transmission signal. Since the signals transmitted by the core wires in the wire harness are different, the core wires will also cause interference with each other, resulting in deviations in the transmitted signal
Moreover, most of the existing control cables are made of flammable materials with poor fire performance.
After burning, small solid particles are produced to form smoke, which reduces the light transmittance, affects people's escape in the event of a fire and is not resistant to high temperature; some materials also contain halogen, and the harmful gas produced after halogen combustion is highly toxic and harmful to the human respiratory system

Abstract

The invention, which relates to the technical field of cable shielding, provides an enhanced shielding layer for a signal control cable. The enhanced shielding layer comprises an inner conductor, an insulating layer, an outer conductor and an outer sheath that are arranged successively from inside to outside. A braiding layer and a shielding layer are arranged between the outer conductor and the outer sheath successively from inside to outside. The shielding layer includes the following raw materials: a glass fiber, graphite powder, a stabilizer, antioxygen, and chlorinated paraffin. Accordingto the invention, with the braiding layer and the shielding layer, overall coating is realized without any slit, so that electromagnetic leakage is avoided and thus the shielding effect is good; andduring the signal transmission process, external interference is prevented and the safety and reliability of the cable are high.

Description
