The utility model content:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of and possesses high environmental-protecting performance, burning the time produces less smog and do 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.
The utility model technical solution problem 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, the beneficial effects of the utility model are 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 the utility model product 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 utility model 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.
