Abstract
The invention discloses mining special cable, including the oversheath outside core and core, it is characterized in that, the polyethylene layer and first screen layer that the core is extruded successively by least one pair of tinned copper wire conductor and in conductive surface are constituted, by at least individual such core stranding, lapping layer, secondary shielding layer and oversheath are set gradually outside the cable core after stranding.The present invention provides mining special cable, is researched and developed for the interference free performance of cable, the performance such as its conductive energy, proof voltage, fire-retardant.
Description
Technical field
The present invention relates to cable, and in particular to mining special cable.
Background technology
In recent years, coal mining enterprise's security incident is taken place frequently, and country is increased to enterprise managing dynamics, does not have installation monitoring camera-shooting to equip in enterprise；The Automatic monitoring systems such as injection, colliery integrated dispatch, centralized control system with monitoring equipment are fully used, as the colliery equipment of high-tech content is widelyd popularize, the common mining signal cable of some original far can not adapt to the jamproof technical requirements of AS using common polyvinyl chloride.
The content of the invention
The present invention provides mining special cable, is researched and developed for the interference free performance of cable, the performance such as its conductive energy, proof voltage, fire-retardant.
The technical scheme that the present invention takes is as follows：Mining special cable, including the oversheath outside core and core, it is characterized in that, the polyethylene layer and first screen layer that the core is extruded successively by least one pair of tinned copper wire conductor and in conductive surface are constituted, by at least individual such core stranding, lapping layer, secondary shielding layer and oversheath are set gradually outside the cable core after stranding.
Further, drainage thread is set between the lapping layer, secondary shielding layer.
Further, the drainage thread is four copper materials, is uniformly set between lapping layer and copper strip shielding layer.
The beneficial effects of the present invention are：The present invention provides mining special cable, is researched and developed for the interference free performance of cable, the performance such as its conductive energy, proof voltage, fire-retardant.
Brief description of the drawings
Fig. 1 is structural section figure of the present invention.
Wherein：1 is conductor, and 2 is insulator, and 3 is screen layer, and 4 is lapping layer, and 5 is drainage thread, and 6 is screen layer, and 7 is oversheath.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described：
Mining special cable, including the oversheath 7 outside core and core, it is characterized in that, the polyethylene layer 2 and first screen layer 3 that the core is extruded successively by least one pair of tinned copper wire conductor 1 and in conductive surface are constituted, by at least 2 such core strandings, lapping layer 4, secondary shielding layer 6 and oversheath 7 are set gradually outside the cable core after stranding.
Drainage thread 5 is set between the lapping layer 4, secondary shielding layer 6.
The drainage thread 5 is four copper materials, is uniformly set between lapping layer 4 and copper strip shielding layer.
The present invention provides mining special cable, is researched and developed for the interference free performance of cable, the performance such as its conductive energy, proof voltage, fire-retardant.
Embodiments of the invention are to introduce its specific embodiment, do not lie in and limit its protection domain.The technical staff of the industry can make some under the inspiration of the present embodiment and change, therefore all equivalent change or modifications done according to the scope of the claims of the present invention, belong in scope of the patent claims of the present invention.
