Abstract
The utility model discloses a high-intensity fluoroplastic insulated and sheath high-temperature resistant control cable, which comprises a plurality of tensile conductors, wherein the tensile conductors are respectively formed by twisting a plurality of tin-plated copper wires by taking an alloy wire as a center; a fluoroplastic insulation layer is respectively covered outside the tensile conductors; the alloy conductors covered with the fluoroplastic insulation layer are twisted into a bundle so as to form a cable core; the outer side of the cable core is covered with a belting layer; the belting layer is characterized in that a plurality of layers of high-temperature resistant glass fabric are wrapped to form an inner layer, and synthesis mica tapes are wrapped to form an outer layer; the outer side of the belting layer is covered with a fluoroplastic sheath layer; steel belts which are arranged in a Chinese character of ''Pin'' and are coaxial with the cable core are arranged in the fluoroplastic sheath layer; and the steel belts are arc-shaped belts. According to the high-intensity fluoroplastic insulated and sheath high-temperature resistant control cable disclosed by the utility model, the tensile strength of the cable is greatly improved according to the design of the steel belts in the sheath layer and the alloy wire in the conductor. Meanwhile, the double-layer structure design of the fluoroplastic and the belting layer are adopted for the insulation and the sheath, therefore the cable has the advantages of high temperature resistance, oil resistance, acid and alkali resistance, excellent corrosion resistance and long service life.
