nullThis utility model solves technical problem and adopts the following technical scheme that a kind of novel low temperature resistant resisting cold instrument cable，This cable includes that anaerobic soft copper skein silk synthesizes soft copper conductor，And be that insulating barrier is as insulated wire cores outside copper conductor，Two insulated wire cores pair twists are line group，The outer overlapping wrapped polyester belt of line group is separated-shielding band，Weaving anaerobic soft copper silk outside separated-shielding band is separated-shielding，Separated-shielding band and separated-shielding composition shielding line group，At least two pairs of shielding line group strands are become cable core，Cable core gap coupling arranges packed layer，The outer overlapping wrapped double-layer polyester band of cable core is for always shielding band，Weave copper free wire outside total shielding band and form total shielding，Total shielding is outer to be extruded the thermoplastic low-smoke halide-free polyolefin jacket that resists cold and forms sealing coat，The wrapped constantan band of sheath sealing coat external series gap is heating metal strip，One layer of oversheath is extruded outside heating metal strip.
Described separated-shielding is at the anaerobic soft copper silk that the outer count of separated-shielding band is 85%；Described total shielding is that count is the copper free wire of 85% outside total shielding band.
Described packed layer uses non-hygroscopic inorganic PP rope to fill.
Described heating metal strip is at the wrapped constantan band of sealing coat external series gap, and clearance rate is 40%.
Beneficial effect
1, conductor uses anaerobic soft copper silk, and twisting pitch controls at 12-14 times, and fine pith adds the stability of conductor.
2, insulating barrier uses IXPE, after cross-linking through electron beam irradiation, and the electric property raising such as cold-resistant, aging, the tension etc. of insulating mechanical performance and current-carrying capacity and short circuit temperature.The longtime running temperature of cable can bring up to 105 DEG C, 125 DEG C, 135 DEG C, even 150 DEG C.
3, screen layer uses shielding line group and always shields, and count is up to 85%, and shielding rejection coefficient is excellent, and the anti-external world is effective, it is ensured that between line pair, signal does not interfere with each other, and distorted signals is little, it is ensured that signal transmission quality.
4, resisting cold function is mainly by the wrapped formation of constantan band gap of high resistivity, when cable is during normal use, constantan band generates heat, produce the heat of uniform temperature, the heat discharged continually is oversheath heating, make outer jacket remain certain temperature in psychro-environment, it is ensured that sheath is the most easy to crack, improve the service life of cable.
