Abstract
The invention discloses a mine-used combined control cable; the cable core is intertwisted by a control cable and a signal cable; a packing layer is arranged in a cable core gap; and a belting layer, a general shielding layer and an outer restrictive coating successively covers outside the cable core and the packing layer. During burning of the combined control cable, the smoke density is very low, no corrosive gas escapes, and no harmful haloid acid substances are produced; the combined control cable not only transmits electric energy and video signals, but also is a special cable integrating functions such as radial and axial water proofness, high flame retardancy and the like; and the combined control cable is particularly applied to coal mine places. In a word, the combined control cable is a new product integrating functions such as environment protection, water proofness, flame retardancy, electric energy and video signal transmission and the like, and has broad market prospect.
Description
Technical field:
The present invention relates to a kind of cable, specifically a kind of combined control electric cable for mining.
Background technology:
At present, the cable of selling on the market has mining control cable, mining signal cable, mining flame-retardant cable, mining communication cable, rubber sheathed flexible cable for mine, communication cable for mine etc., the main performance of these cables is single, and can not adapt to has two and above performance need.In the colliery occasion, not only want electric energy transmitting, line facility is controlled, also need transmission signals, make things convenient for down-hole and top getting in touch, occurring under the situation of accident simultaneously, if cable fire require to produce less smog and does not produce harmful hydracid material, conveniently personnel are rescued, also require cable to have water resistance, under the situation of the inside, colliery ponding, prevent the cable water inlet, normal operation that can holding circuit, and the monitoring of down-hole are therefore to the demands for higher performance of cable.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind ofly possess high environmental-protecting performance, burning the time produces less smog and does not produce harmful hydracid material, can electric energy transmitting, equipment is controlled easily, again can transmission signals, to the monitoring of down-hole, also possesses the cable of good flame retardant property and the good axial block-water performance in footpath simultaneously.
Technical solution problem of the present invention adopts following technical scheme:
Combined control electric cable for mining, described cable conductor are by control cable and signal cable is stranded forms, and the cable core gap is provided with packed layer, are coated with belting layer, total screen and external sheath layer outside cable core and packed layer successively.
Described control cable from-inner-to-outer is made of conductor, insulating barrier and first screen.
Described signal cable reaches polyethylene layer, secondary shielding layer and restrictive coating of being coated on successively outside it by single naked soft circular copper wire and constitutes.
Described packed layer is the polyester yarn packed layer that blocks water, and described belting layer is the low smoke and zero halogen belting layer.
Described conductor is zinc-plated soft copper conductor, and described insulating barrier is the low-smoke halogen-free polyolefin insulating barrier, and described first screen and total screen form by the tinned copper wire braiding.
Described external sheath layer and restrictive coating are made by low-smoke halide-free fireproof composite polyolefine material.
Compared with the prior art, beneficial effect of the present invention is embodied in:
Conductor adopts the zinc-plated soft copper conductor of the 5th class, can prevent the corrosion of moisture content and other harmful substance, anti-electromagnetic interference, packed layer adopts the polyester yarn that blocks water, its water absorption capacity surpasses 40mL/g, insulating barrier, restrictive coating and external sheath layer all adopt the environmental-friendly halogen-free low-smoke polyolefine material, smoke density was very low when product of the present invention had burning, non-corrosiveness gas is overflowed, do not produce harmful hydracid material yet, both electric energy transmitting and vision signal possessed multiple performances such as the axial waterproof in footpath, high flame retardant simultaneously in the special cable of one, were specially adapted to the place, colliery.In a word, this invention product be a kind of with environmental protection, block water, new product that performance such as fire-retardant, electric energy transmitting and vision signal is integrated in one, vast market prospect is arranged.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Number in the figure: 1 conductor, 2 insulating barriers, 3 first screens, 4 packed layers, 5 single naked soft circular copper wires, 6 polyethylene layers, 7 secondary shielding layers, 8 restrictive coatings, 9 belting layers, 10 total screens, 11 external sheath layers.
