Abstract
The invention discloses a mineral insulated fire-proof cable, which consists of conductive cable cores, neutral cable cores, a ceramic fluororubber insulated layer, an alkali-free glass wire warping tape, an embossing copper sheath and a silicone rubber outer sheath, wherein each conductive cable core is formed by wrapping a ceramic fluororubber insulated layer on stranded copper conductors, the outer side of the ceramic fluororubber insulated layer is wrapped with the alkali-free glass wire warping tape, an alkali-free glass wire filling layer is arranged between the ceramic fluororubber insulated layer and the alkali-free glass wire warping tape, the outer side of the alkali-free glass wire warping tape is wrapped with the embossing copper sheath, and the embossing copper sheath is wrapped with the silicone rubber outer sheath; each neutral cable core is formed by pressing wrapping a polyethylene insulated layer on stranded copper conductors; a ground wire core is arranged in each polyethylene insulated layer; each neutral cable core is arranged in an outer side gap between every two conductive cable cores. The cable has the advantages of fireproofness, high-temperature resistance, good mechanical performance, strong overload capacity and low cost.
Description
Technical field
The present invention relates to cable, relate in particular to a kind of mineral insulated cable.
Background technology
Fire safety has become a kind of important leverage measure that ensures national economy fast development, preventing electric fire has become the most important thing, realize this High-Interest Object, mineral insulated cable becomes unique first-selection, and the big-length of this Project-developing has overcome traditional drawing process and produces the fatal shortcoming of fireproof cable both length was short without the mineral insulated cable of transition joint is just in time satisfactory, must do at the scene of laying lengthening joint and produce possible accident potential, therefore the large size mineral insulation fireproof cable of this project development has good promotion prospect and the market competitiveness.This copper with high conductivity is made conductor, the insulation of ceramic fluorubber, and seamless copper pipe is made sheath, and the cable that adopts special process to be made, is mainly used in the cable that modern architecture wiring cable and special industry are used.Due to the particularity of material and structure, the fire prevention of this product, performance high temperature resistant and electric, mechanical, environmental protection aspect are all good.Mineral insulated cable is obtaining increasingly extensive application because of its superior cost performance, and market prospects are good, and added value of product is high.
Summary of the invention
In order to meet above-mentioned requirements, the object of the invention is to provide a kind of mineral insulated cable.
The solution of the present invention is as follows: a kind of mineral insulated cable, it is by conductor wire core, neutral core, ceramic fluorubber insulating barrier, alkali-free glass wool twining package tape, embossing copper sheath and silicon rubber oversheath composition, described conductor wire core is to be formed by the coated twisted copper conductors of ceramic fluorubber insulating barrier, the coated alkali-free glass wool twining package tape in outside of described ceramic fluorubber insulating barrier, between described ceramic fluorubber insulating barrier and alkali-free glass wool twining package tape, be provided with alkali-free glass wool packed layer, the coated embossing copper sheath in outside of described alkali-free glass wool twining package tape, described embossing copper sheath is coated with silicon rubber oversheath, described neutral core is to extrude twisted copper conductors by polyethylene layer to form, a ground core is set in described polyethylene layer, described neutral core is arranged in the outer side clearance between every two conductor wire cores.
Described conductor wire core is made up of the twisted copper conductors of some layers, and every layer of twisted copper conductors forms with prismatic conductor is stranded by some strands, and per share conductor is made up of some conductor monofilament, and direction of lay is between layers contrary.
Every conductor monofilament of described conductor wire core is the single round copper wire that circular copper wire or overlay coating are tin.
Beneficial effect of the present invention: the advantage of this cable is fire prevention, high temperature resistant, good mechanical property, and overload capacity is strong, and cost is low, for universal and popularization widely provides reliable guarantee.
