Abstract
The invention discloses a lighting tensile cable, which comprises three big conductors and one small conductor, wherein insulated layers are arranged outside the big conductors and the small conductor; the small conductor is arranged outside the three big conductors; a plurality of steel wire ropes are arranged between the big conductors and the small conductor; a wrapping layer is arranged outside the big conductors, the small conductor and the steel wire ropes; a shielding layer is arranged outside the wrapping layer; and a sheath layer is arranged outside the shielding layer. According to the lighting tensile cable, as a plurality of steel wire ropes are arranged inside the cable, the strength of the cable is enhanced, the cable is not easy to break or damage, and the cable is suitable for operation in small space for improving lighting.
Description
Technical field
The present invention relates to cable technology field, relate in particular to a kind of illumination tensile cable.
Background technology
Light conduits is often used for, in the operation such as colliery or down-hole small space, often need to pulling crimping by stretching light conduits, easily causes the breakage of cable internal break, need to often change, and can not meet the needs of the daily production of people.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of illumination tensile cable that is suitable for narrow and small working space.
For achieving the above object, the invention provides following technical scheme: a kind of illumination tensile cable, comprise three large conductors, a little conductor, this large conductor and little conductor outside are equipped with insulating barrier, described little conductor is positioned at three large conductor outsides, between described large conductor and little conductor, is provided with several steel wire ropes, and described large conductor, little conductor and steel wire rope are provided with lapping layer outward, described lapping layer is provided with screen outward, and described screen is provided with restrictive coating outward.
Preferably, described three large conductors are isosceles triangle distribution.
Preferably, described screen adopts the wrapped formation of copper strips.
Preferably, described insulating barrier and restrictive coating all adopt ethylene-propylene rubber material.
Adopt the beneficial effect of above technical scheme to be: inside of the present invention is provided with several steel wire ropes and has improved cable intensity, be difficult for making cable that the phenomenons such as damaged fracture occur, be applicable to operation in narrow space and improve illumination.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention 1;
Wherein, 1-large conductor, 2-little conductor, 3-insulating barrier, 4-steel wire rope, 5-lapping layer, 6-screen, 7-restrictive coating.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Describe the preferred embodiment of the present invention in detail below in conjunction with accompanying drawing 1: a kind of illumination tensile cable, comprise three large conductors 1, a little conductor 2, be equipped with insulating barrier 3 at large conductor 1 and little conductor 2 outsides, be positioned at three large conductor 1 outsides at little conductor 2, between large conductor 1 and little conductor 2, be provided with several steel wire ropes 4, at large conductor 1, the outer lapping layer 5 that is jointly provided with of little conductor 2 and steel wire rope 4, outside lapping layer, 5 are provided with screen 6, outside screen 6, be provided with restrictive coating 7, three large conductors 1 are isosceles triangle and distribute, adopt the wrapped formation of copper strips at screen 6, this insulating barrier 3 and restrictive coating 7 all adopt ethylene-propylene rubber material.
Adopt the beneficial effect of above technical scheme to be: inside of the present invention is provided with several steel wire ropes and has improved cable intensity, be difficult for making cable that the phenomenons such as damaged fracture occur, be applicable to operation in narrow space and improve illumination.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
