Temperature-resistant and cold-resistant control cable with fluoroplastic insulating thermoplastic elastic sheath

Abstract

The invention discloses a temperature-resistant and cold-resistant control cable with a fluoroplastic insulating thermoplastic elastic sheath. The cable comprise conductors, a wrapping tape and a second sheath. The wrapping tape is wound on the outer surface of the side edge of first sheaths; fillers are filled between the first sheaths and the wrapping tape. The outer surface of the side edge ofthe wrapping tape is provided with an armor tape, the outer surface of the side edge of the armor tape is sleeved with the second sheath, the number of the conductors and the number of the first sheaths are respectively seven, the thickness of the second sheath is larger than that of the first sheath, the second sheath and the first sheaths are made of fluoroplastic materials; and the wrapping tape is made of non-woven fabric materials. According to the temperature-resistant and cold-resistant control cable with the fluoroplastic insulating thermoplastic elastic sheath, the control cable hasa double-thermal-insulation structure, the temperature resistance and cold resistance of the cable can be effectively improved, the cable can be suitable for a high-temperature or low-temperature environment, and the application range of the cable is widened.

Description

technical field [0001] The invention belongs to the technical field of cables, and more specifically relates to a temperature-resistant and cold-resistant control cable with a fluoroplastic insulated thermoplastic elastic sheath. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outside is covered with a highly insulating covering. The cable has Internally energized, externally insulated. [0003] The existing fluoroplastic insulated thermoplastic elastic sheath temperature-resistant and cold-resistant control cables have certain disadvantages during use. Traditional control cables adopt a single-layer protection structure design, so that they do not have a temperature-insulating protection structure. When the temperature is low, the surface of the cable is affected by the temperature, which is prone to hardening...

[0003] The existing fluoroplastic insulated thermoplastic elastic sheath temperature-resistant and cold-resistant control cables have certain disadvantages during use. Traditional control cables adopt a single-layer protection structure design, so that they do not have a temperature-insulating protection structure. When the temperature is low, the surface of the cable is affected by the temperature, which is prone to hardening and fracture. Secondly, when the temperature is high, the sheath of the cable is prone to softening in the high temperature environment, causing the cable to burn, which has certain safety hazards; When performing wrapping proces
