Compression-resistant, tensile and anti-interference polyvinyl chloride insulated thin steel wire armored control cable

Abstract

The invention discloses a compression-resistant, tensile and anti-interference polyvinyl chloride insulated thin steel wire armored control cable which comprises a cable core. The cable core is formedby twisting an insulated wire core and a control cable in a pair mode. The gap position of the cable core is filled with an elastic plastic body, the cable core is externally wrapped with a first ultrathin steel wire armored layer, the first ultrathin steel wire armored layer is externally provided with an inner sheath, an oxygen isolation layer is arranged outside the inner sheath, the oxygen isolation layer is externally wrapped with a second ultrathin steel wire armored layer, and finally the cable is externally provided with a metal ceramic lining composite tube. The compression-resistant, tensile and anti-interference polyvinyl chloride insulated thin steel wire armored control cable has the advantages of very high tensile strength, good flame retardancy performance, good safety performance, good shielding property, good interference resistance, long service life and the like.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a pressure-resistant, tensile-resistant, and interference-resistant polyvinyl chloride insulated thin steel wire armored control cable. Background technique [0002] At present, as the office and residential floors are getting higher and higher, and the mechanization and automation of coal mines are constantly improving, electrical control technology is of great significance in the production of high-rise buildings and coal mines. Due to the large vertical drop and the special environment, the control cables used for laying in fixed places for control signal connection of control, monitoring circuits and protection lines are mainly composed of cable cores composed of polyvinyl chloride insulated single wires and polyvinyl chloride outer sheaths, but The environment where the cable has a large vertical drop is complex, the working conditions are harsh, and the movement is frequent,...

Due to the large vertical drop and the special environment, the control cables used for laying in fixed places for control signal connection of control, monitoring circuits and protection lines are mainly composed of cable cores composed of polyvinyl chloride insulated single wires and polyvinyl chloride outer sheaths, but The environment where the cable has a large vertical drop is complex, the working conditions are harsh, and the movement is frequent, the service life is not long, and the area where the gas accumulates is very dangerous. Abrasiveness and resistance to external tension are very high
