Abstract
The invention discloses a coal mining safety cable. The coal mining safety cable comprises a copper wire core (1), wherein a nylon sleeve (2) is coated on the outer surface of the copper wire core (1); a rubber sleeve (3) is sleeved outside the nylon sleeve (2); and a cable support (4) is arranged outside the rubber sleeve (3).
Description
Technical field
The present invention relates to a kind of colliery safety cable.
Background technology
The cable wear resistance of current underground mine use is poor, and use and easily breakage after water soaking long-time, insulation property are poor, and therefore useful life is shorter.
Summary of the invention
The invention provides a kind of coal mine cable, its long service life, and resistance to wear is good, can insulating properties be improved simultaneously.
Present invention employs following technical scheme: a kind of colliery safety cable, it comprises copper wire core, has nylon jacket at the outer surface of copper wire core, has rubber case at nylon jacket overcoat, is provided with cable bearer in the outside of rubber case.
The bottom of described cable bearer is provided with bracket with foldable leg.Insulation glue-line is scribbled between described nylon jacket and rubber case.Described copper wire core is set to triangle copper wire core.
The present invention has following beneficial effect: after have employed above technical scheme, and the present invention can realize double shielding like this, effectively improves the insulation property of cable, and can prevent wearing and tearing.The present invention is provided with cable bearer, easy to use like this, can use anywhere.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
