Abstract

The utility model discloses an anti-compression flat cable. The anti-compression flat cable comprises conductors. The conductors are formed in a way that a plurality of tinned soft copper wires are subjected to multiple-bundle twisting. An outer side of each conductor is covered by a highly-elastic modulus EP rubber insulating layer. Four conductors are disposed in a way that every two conductor are tangent to each other, and an outer side of the four conductors is covered by a multi-layer mineral wrapping strip overlapped wrapping layer, and thus a core is formed. The periphery of each core is provided with rubber skeletons. Two cores are arranged in parallel, and an outer side of the two cores is sequentially covered by a polyester film strip, a crosslinked polyethylene external insulation layer of a flat structure, a copper wire woven separated shielding layer, a glass filament fireproof layer and a flame-retardant rubber oversheath. A wire rope is arranged between the crosslinked polyethylene external insulation layer of the flat structure and the copper wire woven separated shielding layer.

Description

A kind of anti-collapse flat cable

Technical field

The utility model relates to cable technology field, relates in particular to a kind of anti-collapse flat cable.

Background technology

Utilization is more severe with the cable environment for use on traffic track, when track traffic operation, often accelerate, and can produce vibrations, thereby the operation meeting of long-term acceleration shock exerts an influence to the cable on it, thereby the cable that need to be used for track traffic need to have stronger physics compressive property, wear-resisting.

Utility model content

The utility model object is exactly the defect in order to make up prior art, and a kind of anti-collapse flat cable is provided.

The utility model is achieved through the following technical solutions:

A kind of anti-collapse flat cable, include conductor, described conductor adopts many tin annealed copper wires to carry out compound bundle strand and forms, be surrounded by the ethylene propylene rubber insulated layer of high resiliency modulus in conductor outside, by the tangent placement between two of four conductors and be surrounded by the overlapping lapping layer of multilayer mineral band material in outside and form core, surrounding at core is respectively equipped with rubber skeleton, two cores are placed and are surrounded by successively in outside mylar tape side by side, the crosslinked polyethylene external insulation layer of flat structure, proof copper-wire braided sub-shield, glass fiber fireprotection layer and flame-proof silicon rubber sheath, between the crosslinked polyethylene external insulation layer of flat structure and proof copper-wire braided sub-shield, be provided with steel wire rope.

The utility model has the advantages that: the utility model is simple in structure, rationally novel in design, be provided with rubber skeleton by the surrounding at core, greatly improve the tension compressive property of cable, resistance to wear is good, long service life.
