Abstract
The utility model discloses a fluoroplastic insulation high-temperature hook up wire, which comprises a conductor and an insulation layer, wherein the insulation layer wraps the conductor, a belting layer wraps the insulation layer, the belting layer is formed by two layers of polytetrafluoroethylene films and a layer of mesh polytetrafluoroethylene films bonded between the two layers of polytetrafluoroethylene films, and a shielding layer wraps the belting layer. The conductor is formed by twisting a plurality of copper wires which are silver plated, the insulation layer adopts fluoroplastic materials, and the shielding layer is formed by weaving the silver plated copper wires. The shielding layer is an outer shield with the density over 85%. Due to the fact that the belting layer is formed by two layers of polytetrafluoroethylene films with the layer of mesh polytetrafluoroethylene films bonded in between and the fluoroplastic materials adopted are insulated, the fluoroplastic insulation high-temperature hook up wire has higher electricity transmitting capability, high and low temperature resistance, abrasion resistance, excellent mechanical toughness and anti-jamming capability, is free of thermal shrinkage, small in outer diameter and light in weight, thereby meeting the requirement for space and weight of mechanical devices and providing safe and reliable mechanical performance and chemical performance for airplanes and mechanical equipment.
