Description

A kind of mine-shield electric drill cable

Technical field

The utility model relates to a kind of electric drill cable, specifically a kind of mine-shield electric drill cable.

Background technology

Coal is the main energy sources of China, it and economic construction and people's daily life are closely related, the yield of coal in China is all increasing progressively every year, the safety in production in colliery is extremely important in coal production, it does not still guarantee to produce the primary condition of normally carrying out, it also is the important leverage of miner's life security, receive the concern of society, in various safety precautionss, eliminate the spark that electric circuit in well produces and avoid the breaking out of fire important content that is absolutely necessary, at present general cable is easy to the fault that is short-circuited or leaks electricity, inevitably can produce spark, this may cause major accident in the situation that gas exists, therefore improve existing Coal Electricity brill cable and have great importance.

Summary of the invention

In order to address the above problem, the utility model provides a kind of have good insulating performance and shielding properties and colliery wear-resisting, long service life shielding electric drill cable.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

The utility model is a kind of mine-shield electric drill cable, the cable core of cable comprises several power line core conductors, a ground wire core conductor and a control line core conductor, arranged outside at every power line core conductor has the first control line core insulation layer, arranged outside at every layer of first control line core insulation layer has control core semiconductive shielding layer, arranged outside at every layer of control core semiconductive shielding layer has the first control core restrictive coating, arranged outside at the control line core conductor has the second control line core insulation layer, arranged outside at the second control line core insulation layer has the control conductor screen, arranged outside at the control conductor screen has the second control core restrictive coating, arranged outside at the ground wire core conductor has ground wire core insulation layer, arranged outside at ground wire core insulation layer has covering, several power line core conductors, ground wire core conductor and control line core conductor are through twining by interior shield semiconductors layer after stranded, arranged outside at interior shield semiconductors layer has insulating barrier, arranged outside at insulating barrier has the outer semiconductor screen, the arranged outside of shield semiconductors layer has restrictive coating outside, arranged outside at restrictive coating has wearing layer, in the arranged outside of wearing layer external sheath layer is arranged.

Further improvement of the utility model is: be filled with the gypsum that prevents that moisture enters in the colliery before several power line core conductors, ground wire core conductor and control line core conductor and interior shield semiconductors layer.

Further improvement of the utility model is: restrictive coating is the nylon mesh grid restrictive coating.

The beneficial effects of the utility model are: cable of the present utility model is by being filled with gypsum before several power line core conductors, ground wire core conductor and control line core conductor and interior shield semiconductors layer, prevent that effectively moisture enters into cable in the colliery, affect the normal use of cable, restrictive coating adopts nylon mesh grid, and flexibility is higher, and resistance to bend(ing) can be better, skin at cable also has wearing layer, wear-resistant, oil resistant, the long service life of cable.

The utility model is rational in infrastructure simple, manufactures easily, and cost is low, has good flexibility, and has good shielding and insulation property, long service life.
