Description

A kind of metal screen supervision type rubber sleeve flexible cable for colliery

Technical field

The utility model relates to colliery field of power transmission, particularly relates to a kind of metal screen supervision type rubber sleeve flexible cable for colliery.

Background technology

The cable of at least two stranded similar ropes normally often organized by cable by several or several groups of wires, often organize mutually insulated between wire, and be often twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.

Now, the existing cable for colliery in use also exists certain hidden danger, such as because cable needs often to move back and forth, thus causes control conductor very easily to rupture, and cable is scrapped, so decrease the useful life of cable.

Utility model content

In order to solve the problem, the utility model provides a kind of metal screen supervision type rubber sleeve flexible cable for colliery, possesses the control conductor not advantage such as easy fracture, long service life.

Above-mentioned a kind of metal screen supervision type rubber sleeve flexible cable for colliery, comprise control line, power line, ground wire, semi-conductive layer and sheath, described control line, power line, ground wire are all arranged at the inside of semi-conductive layer, described sheath is arranged at the outside of semi-conductive layer, wherein, described control line comprises the steel wire rope, control conductor and the control line insulating barrier that set gradually from the inside to the outside, and described control conductor is proof copper-wire braided structure; Described power line comprises the power wire core, power line insulating barrier and the power line screen that set gradually from the inside to the outside, and described power line screen comprises semi-conductive tape and tincopper fuse wire braided armor; Described ground wire comprises bare area line and Ground wire with insulation ocver, and described bare area line comprises steel wire rope and bare area core, and described Ground wire with insulation ocver comprises the steel wire rope, Ground wire with insulation ocver core and the Ground wire with insulation ocver insulating barrier that set gradually from the inside to the outside.

In the said equipment, the quantity of described power line is 3, and the area in described power wire core cross section is 35mm ².

In the said equipment, the quantity of described bare area line and Ground wire with insulation ocver is 1.

In the said equipment, the quantity of described control line is 1, and the area in control conductor cross section is 6mm ².

Advantage of the present utility model and beneficial effect are: the utility model provides a kind of metal screen supervision type rubber sleeve flexible cable for colliery, by adopting type of weave to add steel cord structure control conductor, the situation decreasing cable control conductor easy fracture when bending occurs, and finally reaches the object in the useful life adding cable.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the internal structure schematic diagram of rubber sleeve flexible cable in the utility model.

Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.

As shown in Figure 1; the utility model describes a kind of metal screen supervision type rubber sleeve flexible cable for colliery; comprise control line, power line, ground wire, semi-conductive layer 7 and sheath 8; and control line, power line, ground wire are all arranged at the inside of semi-conductive layer 7; sheath 8 is then arranged at the outside of semi-conductive layer 7, plays certain protective effect.

Wherein, control line comprises the steel wire rope 11, control conductor 1 and the control line insulating barrier 2 that set gradually from the inside to the outside; Preferably, the quantity of control line is 1, and the area of section of control conductor 1 is 6mm2.

In addition, above-mentioned control conductor 1 is proof copper-wire braided structure, thus the situation decreasing cable control conductor easy fracture when bending occurs, and then adds the useful life of cable;
