Abstract
Disclosed is a novel fireproofing cable, the utility model relates to the technology field of the cable, especially to the technology field of fireproofing cable. The utility model includes an twisted conductor, an insulating material, a filler, a belting and a sheath, each conductor is intertwisted with multiple copper wires, and the outside of the conductor is disposed with inorganic belting wrapping insulation, the outside of the insulating layer is disposed with inorganic wrapping layer, and the outside of the inorganic wrapping layer is disposed with copper strip longitudinal winding and corrugating sheath. The utility model has good softness and processability with the length of no limitation, as well as has low equipment investment and excellent comprehensive performance.
Description
Technical field
The utility model relates to the cable technology field, relates in particular to the fireproof cable technical field.Be applicable to explosion-proof places such as oil, chemical industry, colliery, Generators; The demanding occasion of public safeties such as underground that subway, tunnel etc. are moist; It is the optimal selection that there are the high-temperature operation district in steel mill, copper work, aluminium manufacturer etc.
Background technology
Modern architecture is more and more higher to fire protection requirement, and the past all is to adopt the plastic insulation plastic jacketed cable.A lot of now buildings all require to use fireproof cable, and fireproof cable is by copper conductor at present, and inorganic insulating material and copper sheath combination process.Current production technology has three kinds of prefabricated magnesium oxide porcelain knob method, the automatic canned method of magnesia powder and argon arc welding sequential welding connections.First kind and second kind restriction that is subjected to the length of pipe and line base, production length is not long, and magnesia powder makes moist easily, influences insulation property.The third equipment investment height, raw material processing charges height.
Summary of the invention
The purpose of this utility model is, provides a kind of above-mentioned defective that overcomes, a kind of novel fireproof cable that flexibility is good, processability is good, length is unrestricted, equipment investment is few, combination property is the most excellent.
The utility model includes stranded conductor, insulating material, filler, band and sheath, it is characterized in that every conductor adopts many copper wires stranded, the conductor peripheral hardware has inorganic band lapped insulation, the insulating barrier peripheral hardware has inorganic lapping layer, and inorganic lapping layer is provided with the vertical bag of copper strips embossing sheath outward.
Inorganic band adopts mica tape.
Outside the vertical bag of copper strips embossing sheath, also can be provided with the anticorrosion oversheath of one deck.
The utility model flexibility is good, processability is good, length is unrestricted, equipment investment is few, combination property is very excellent.
