Abstract
The utility model relates to the cable technical field, belongs to a medium voltage cable for a coal cutter on mine, composed of a control wire core conductor, a screening layer, an insulation layer, a lapping layer, a weaving layer, a fill core and a rubber sheath. The screening layer is clad on the control wire core conductor and an insulation layer is clad between the inner screening layer and the outer screening layer and the control wire core conductor uses composite structure and the center is multi-stranded helical copper conductor. The insulation layer, the screening layers and three copper conductor cores form cable cores and a lapping layer is clad on the three copper conductor cores and lapping layers are clad on the three cable cores and the clearance of the three cable cores are filled with fill cores and the inner sheath is clad outside the lapping layer and the weaving layer is clad on the outer layer of the inner sheath and the outer sheath is clad on the weaving layer. The advantages of the cable are that: firm and durable cable due to terylene fiber weaving layer, better cable insulation due to bad water absorption performance of the terylene and firmness and durability, flexibility, environmental protection and innocuity due to non-woven fabrics as the material of the lapping layer.
Description
Technical field
The utility model relates to the cable technology field, refers in particular to the coal-winning machine midium voltage cable on the mine.
Background technology
The electric cable for coal mining machine that in the colliery, uses, generally by the control core, insulating barrier and neoprene sheath are formed, the cross section of control line core conductor is less, during work, under the frequent crooked situation of cable, the control line core conductor ruptures easily under stretching and flecition and scraps, cause controlling core and can not normally export use, the producer that has prevents the fracture of control line core conductor with the steel wire coating, though can strengthen the useful life of control line core conductor like this in order to overcome this shortcoming, but Heavy Weight, the insulation property of cable are poor, use inconvenient, dangerous.
The utility model content
The purpose of this utility model provides a kind of in light weight, good insulating, under frequent operational environment, still can stablize the coal-winning machine midium voltage cable on the mine of permanent use.
The purpose of this utility model is achieved in that
Coal-winning machine midium voltage cable on the mine, outer surface at conductor is coated with internal shield, insulating barrier and outer shielding layer formation control core successively, in the outside adjacent gap of three control cores that are triangularly arranged, be provided with and fill out core, at the control core with fill out the core periphery and be coated with nonwoven fabrics lapping layer, semiconductor tape lapping layer, inner sheath, braid and oversheath successively.
Above-mentioned conductor is to compile with multiply tin-coated copper skein silk to form.
Above-mentioned internal shield and outer shielding layer all adopt the semi-conductive rubber mixture to make.
Above-mentioned insulating barrier is to make with ethylene-propylene rubber.
Above-mentioned braid is to form with the polyster fibre braiding.
Above-mentioned inner sheath is to make with neoprene.
Above-mentioned oversheath is to make with haloflex.
The utility model is compared the outstanding advantage of present technology:
1, the utility model makes cable durable owing to adopt the polyster fibre braid, and it is lighter that weight is compared steel wire braid, and owing to terylene does not absorb water, thereby make the insulating properties of cable better.
2, the material that adopts of lapping layer is a nonwoven fabrics, and it is durable that it is not only tough, and softness, environmental protection, nontoxic.
Description of drawings
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, referring to Fig. 1:
Coal-winning machine midium voltage cable on the mine, outer surface at conductor 1 is coated with internal shield 2, insulating barrier 3 and outer shielding layer 4 formation control cores successively, in the outside adjacent gap of three control cores that are triangularly arranged, be provided with and fill out core 5, at the control core with fill out core 5 peripheries and be coated with nonwoven fabrics lapping layer 6, semiconductor tape lapping layer 7, inner sheath 8, braid 9 and oversheath 10 successively.
Above-mentioned conductor 1 is to compile with multiply tin-coated copper skein silk to form.
Above-mentioned internal shield 2 and outer shielding layer 4 all adopt the semi-conductive rubber mixture to make.
Above-mentioned insulating barrier 3 is to make with ethylene-propylene rubber.
Above-mentioned braid 9 is to form with the polyster fibre braiding.
Above-mentioned inner sheath 8 is to make with neoprene.
Above-mentioned oversheath 10 is to make with haloflex.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection range of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection range of the present utility model.
