Abstract
The utility model provides a mining warp resistance flexible cable. A cable core of the cable is formed by multi-ply nickel plating soft brass wires intertwisted in a same direction, which can guarantee flexibility of the cable. A wrapping extrusion layer outside the cable core makes the combination of the multi-ply nickel plating soft brass wires tighter, which is more conducive to be used in hostile environment; in addition, a net structure inner sheath layer interweaved by a thermoplastic resin insulating layer and high flexible carbon fiber provides a larger stretching space for the cable to cope with cable distortion situations.
Description
Technical field:
The utility model belongs to the power cable field, particularly a kind of mining distortion resistant flexible cable.
Background technology:
Mining cable refers to ground installation and the underground equipment electric wire cable product of the industrial usefulness of coal mining, comprise coal-winning machine, communication on the transporter, illumination and signalling arrangement cable, and the feed cable used of electric drill cable and underground moving transformer station etc., but the environment under the mine is abominable, often collide frequently and pull, traditional mining cable tensile strength is low, distortion easily is distorted in the process of pullling, substantially can not satisfy the condition of modern underground work, mining cable belongs to the higher product of cable industry technology content, mining cable in the market is very general, such as mine control cable, communication cable for mine etc., although these cables have increased the intensity of cable to a certain extent, but do not increase the warp resistance of cable, can not make cable better be applicable to the environment of down-hole, and the cost of making is expensive, useful life is short, can not satisfy the environmental requirement of modern underground work.
Summary of the invention:
In order to address the above problem, the utility model provides a kind of mining distortion resistant flexible cable.
A kind of mining distortion resistant flexible cable of the utility model is characterized in that this cable comprises core layer and restrictive coating from inside to outside successively; Described core layer is comprised of multiply and stranded in the same way nickel plating soft copper silk conductor, wrapped extruded layer and insulating barrier; Described nickel plating soft copper silk conductor outer cladding be the wrapped extruded layer of high flexibility resistant polyester squash type; Described wrapped extruded layer outer cladding be the thermoplastic elastomer resin insulating barrier; Described insulating barrier outer cladding be restrictive coating, described restrictive coating comprises inner restrictive coating and external sheath layer, described inner restrictive coating is coated on outside the insulating barrier; Described inner restrictive coating is coated with external sheath layer.
Described multiply nickel plating soft copper silk conductor is stranded in the same way, and has adopted the metal structure extrusion process, so that conductor is smooth, has saved the space;
Described inner restrictive coating is that the high flexibility carbon fiber wears mutually the network structure that interweaves;
Described external sheath layer is the high-performance carbon fibre fireproof silicone rubber.
A kind of mining distortion resistant flexible cable that the utility model provides, the core of this cable is stranded in the same way by multiply nickel plating soft copper silk, this combination has guaranteed the flexibility of cable, the wrapped extruded layer that core is outer is so that multiply nickel plating soft copper silk combination tightr, be more conducive in rugged environment, use, add thermoplastic elastomer resin insulating barrier and high flexibility carbon fiber and wear mutually the cancellated inner restrictive coating that interweaves, so that cable has larger extending space, deal with the twisting situation of cable.
Description of drawings:
Fig. 1 is the cross section structure schematic diagram of a kind of nanoscale environment protection high flame resistance silicone rubber for cable of providing of the utility model.
