Abstract
A kind of steel wire reinforced power cable.It comprises the conductor that places the cable center position, and the conductor outside is set with interior semi-conductive layer, insulating barrier, outer semiconducting layer successively; Each conductor also is provided with packing material between any two; Outside at conductor and packing material is set with nonwoven layer, sheath successively, and described sheath exterior periphery is provided with the steel wire floor of even armouring, in the outer cover of this steel wire floor sheath is housed, and the outer semiconducting layer outer cover of described conductor is equipped with the copper strips screen; Also be set with steel band between described steel wire floor and the sheath and tighten layer, and this steel band tighten the layer thickness be 0.12～0.17mm.The present invention is simple in structure, easy to make, when extruding sheath, production also can guarantee the rounding property of cable, can effectively avoid destruction sheath because steel wire arches upward, and influence the normal use of cable, improve the whole pull resistance and the stability of whole cable structure, electrical property and stable mechanical performance, economical and practical.
Description
Technical field
The present invention relates to a kind of power cable, the steel wire reinforced power cable of colliery use specifically.
Background technology
In extruded insulation power cable GB/T 12706-2002 standard, be generally rated voltage and be moulding the cable insulation, moulding the cable sheath power cable of 0.6/1kV～26/35kV, its cable all is transmission high-voltage power cables, generally fixedly lays use, does not move use.But this cable needs cable vertically to go into the well when using in the colliery, and long-time vertical placement of cable do not having under other the external force situation, even if the deadweight of cable itself also can make cable be destroyed, influence is used and operating efficiency; The construction of cable that has thicker wire, LWA light wire armoured cable, its objective is the whole pulling force of strengthening cable, the steel wire of armouring can arch upward after a period of time but this cable uses, the oversheath arch of cable is broken, in the serious useful life that shortens cable, become a difficult problem that perplexs cable manufacturing enterprise and user.
Summary of the invention
The present invention be directed to many defectives that existing cable exists, provide a kind of simple in structure, can effectively avoid the steel wire reinforced power cable that causes sheath to destroy owing to arching upward of steel wire.
Realize that the technical scheme that the foregoing invention purpose adopts is: a kind of steel wire reinforced power cable, comprise the conductor that places the cable center position, the conductor outside is set with interior semi-conductive layer, insulating barrier, outer semiconducting layer successively; Each conductor also is provided with packing material between any two; Outside at conductor and packing material is set with nonwoven layer, sheath successively, and described sheath exterior periphery is provided with the steel wire floor of even armouring, in the outer cover of this steel wire floor sheath is housed, and the outer semiconducting layer outer cover of described conductor is equipped with the copper strips screen; Also be set with steel band between described steel wire floor and the sheath and tighten layer, and this steel band tighten the layer thickness be 0.12～0.17mm.
Compared with prior art, the present invention is simple in structure, easy to make, when extruding sheath, production also can guarantee the rounding property of cable, can effectively avoid destruction sheath, and influence the normal use of cable, improve the whole pull resistance and the stability of whole cable structure because steel wire arches upward, electrical property and stable mechanical performance, economical and practical.
Description of drawings
Fig. 1 is a section structure schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples in detail the present invention is described in detail.
Referring to accompanying drawing 1, in the present embodiment, this steel wire reinforced power cable, the cable center position is provided with three copper conductors 1, and the outside of each copper conductor 1 is set with interior semi-conductive layer 2, insulating barrier 3, outer semiconducting layer 4 successively.Three copper conductor 1 gaps between any two also are provided with packing material 10.Be set with nonwoven layer 6, sheath 7 that copper conductor 1 and packing material 10 are packed tightly successively in the outside of copper conductor 1 and packing material 10 integral body, the outside of this sheath 7 is provided with the steel wire of even armouring along circumference, constitute steel wire floor 8, the outermost layer sheath 11 of cable is housed in the outer cover of this steel wire floor 8.The outside of the outer semiconducting layer 4 of each copper conductor 1 also is respectively installed with copper strips screen 5; Also be set with the steel band that constitutes by galvanized steel strip between steel wire floor 8 and the sheath 11 and tighten layer 9, and this steel band to tighten that layer 9 thickness is generally be 0.12～0.17mm, and in the present embodiment, the thickness that this steel band is tightened layer 9 is 0.15mm, is optimum thickness.
More than the disclosed structure that packs tightly only for one embodiment of the present of invention, but the present invention is not limited thereto, any those skilled in the art can think variation, all should drop within protection scope of the present invention.
