Abstract
The utility model relates to a fluorinated ethylene propylene insulated instrument cable with a high-temperature-resistance sheath. The instrument cable comprises conductors. The exteriors of the conductors are pressingly wrapped by insulating layers and inner shielding layers successively to form wire cores; a plurality of wire cores are pressingly wrapped by a wrapping layer to form a cable core; padding is arranged in the cable core; an outer shielding layer and a sheath layer are successively arranged outside the cable core from inside to outside; and current-lead wires are arranged in the wire cores and the outer shielding layer. The instrument cable of the utility model is advantageous in flame retardant, shielding, antistatic and explosion-proof properties, small distributed parameters as well as external interference resistant performance and resistance to crosstalk among lines; and the instrument cable is suitable for aircraft industry, steel works, petroleum industry, chemical industry and is applicable to other occasions where loops should be controlled and monitored and lines should be protected with operating temperature below 200 DGE C.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of perfluoroethylene-propylene insulation and high temperature resistant sheath instrument cable.
Background technology
Present common instrument cable is polyethylene insulation, the black pvc jacket structure, but be laid in the cable in the high temperature places such as steel mill, petrochemical plant, require that cable has fire-retardant, shielding, antistatic, explosion-proof, distributed constant is little, the characteristics such as anti-external interference and line-to-line crosstalk, common cable can not satisfy this requirement.
