Problems solved by technology

At the same time, the environment for cable laying is becoming more and more complex, and the environmental interference and mutual interference between cables are becoming more and more serious.
The traditional control cable has a simple shielding structure, poor shielding effect, and weak anti-interference ability. In an environment with severe electromagnetic interference, the transmission quality is affected, which leads to potential safety hazards in the use of instruments and lines.

Abstract

The invention discloses an anti-electromagnetic interference control cable relating to the technical field of control signal transmission. The anti-electromagnetic interference control cable comprises a plurality of strands of thin bare copper wire conductors twisted into a beam, a core wire insulation layer, an inner jacket, a braided shield layer and an outer jacket, wherein the copper wire conductors wrapped with the core wire insulation layer are bundled by the inner jacket, the braided shield layer is wrapped on the outer layer of the inner jacket, and the outer jacket is wrapped on the outer layer of the braided shield layer. The anti-electromagnetic interference control cable is reasonable in design and simple in structure, is greatly improved in shielding effect because the shield is braided from tinned copper wires, can effectively ensure the quality of transmitted signals of the cable in an environment of serious interference of an electromagnetic field, ensures reliable and stable operation of a connecting device, and can be widely applicable to being installed in occasions possibly causing signal transmission distortion due to electrical interference.

Description

technical field [0001] The invention relates to the technical field of control signal transmission, in particular to an anti-electromagnetic interference control cable. Background technique [0002] With the advancement of science and technology and the development of the national economy, various advanced instruments and controls are continuously introduced and used, and the number is also increasing, and the monitoring lines and protection circuits are also increasing. At the same time, the environment for laying cable lines is becoming more and more complex, and the interference between the environment and the cables is becoming more and more serious. Traditional control cables have a simple shielding structure, poor shielding effect, and weak anti-interference ability. In an environment with severe electromagnetic interference, the transmission quality will be affected, resulting in potential safety hazards in the use of instruments and lines.
