Abstract
The utility model discloses a cold-resistant high-temperature-resistant control cable, which is composed of power line cores, heating wire cores, a copper belt wrapping layer, a polyethylene inner sheath layer, a copper-clad steel armor layer and a polyethylene outer sheath, wherein each power line core is formed by extruding a silicon rubber insulating layer, an aluminum-plastic composite wrapping layer, a tinned copper wire braided shielding layer and a crosslinked polyolefin insulating layer on silver-plated copper wire alloy conductors from outside to inside; each heating wire core is formed by extruding a crosslinked polyethylene insulating layer on a heating conductor; the copper belt wrapping layer extrudes the three power line cores and the three heating wire cores to form a cable core; a flame-retardant filling layer is arranged in a gap of the cable core; and the polyethylene inner sheath layer, the copper-clad steel armor layer and the polyethylene outer sheath are sequentially extruded on the copper belt wrapping layer from inside to outside. The cold-resistant high-temperature-resistant control cable improves the cold resistance and high temperature resistance of products, has excellent mechanical property and good electromagnetic shielding performance, is large in current-carrying capacity, and has high overload protection performance.
Description
Technical field
The utility model relates to cable, relates in particular to a kind of cold-resistant high temperature resistance control cable.
Background technology
Cold-resistant high temperature-resistant cable is the important development direction of modern safety electric energy drive technology, in recent years, there is very large development in the China that is applied in of various cold-resistant high temperature-resistant cables, and obtain good effect, and cold-resistant and high temperature resistant having higher requirement to cable, and require to possess good mechanical performance and intensity.
