Abstract

The utility model discloses an anti-compression type power cable comprising a main conductor, control conductors and a cross rubber frame; the main conductor and the control conductors are respectively formed by twisting a plurality of galvanizing and tin-coated copper wire harnesses; the main conductor and the control conductor are respectively wrapped in sequence by a fluoroplastic insulating layer and a high strength terylene fiber braid layer; the center of the cross rubber frame is provided with a through hole; the main conductor is arranged in the through hole; four corners of the cross rubber frame are respectively provided with the control conductors; the main conductor and the control conductors are wrapped in sequence by a chlorosulfonated polyethylene inner sheath, a three-layer galvanizing tin mixture steel band armoring layer, a semiconductive rubber shield layer, a glass fiber fireproof layer and an oversheath; an inner wall and an outer wall of the semiconductive rubber shield layer are respectively coated by bonding agent. The anti-compression type power cable employs the cross frame to improve the intensity of the cable, so the cable is hardly damaged, and the cable is better in insulation property and fireproof performance.

Description

A kind of Anti-pressure power cable

Technical field

The utility model relates to cable technology field, relates in particular to a kind of Anti-pressure power cable.

Background technology

Conventional armoured power cable structure is that wrapped clad steel band carries out armouring, because construction wrong often causes cable bad, affects the use of power cable, and affect the work of power department when cable construction, increases workload, needs to improve.

Utility model content

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

The utility model is achieved through the following technical solutions:

A kind of Anti-pressure power cable, include leading body, control conductor and cross rubber skeleton, described leading body and control conductor all and tin-coated copper wire harness strand zinc-plated by multiply form, at leading body and control conductor outside, be coated with successively fluoroplastic insulation layer and high tenacity polyester fiber silk braid, center at cross rubber skeleton has through hole, in through hole, be provided with leading body, place, four angles at cross rubber skeleton is respectively equipped with control conductor, and in outside, be coated with successively chlorosulfonated polyethylene inner sheath, three layers of zinc-plated tin mixture steel-tape armouring layer, semi-conductive adhesive screen, glass fiber fireprotection layer and oversheath, on the inner and outer wall of semi-conductive adhesive screen, scribble respectively adhesion agent.

The utility model has the advantages that: the utility model is by being used cross bracket, increase the intensity of cable, not fragile, be coated with chlorosulfonated polyethylene inner sheath, three layers of zinc-plated tin mixture steel-tape armouring layer, semi-conductive adhesive screen, glass fiber fireprotection layer and oversheath, make the insulation property of cable, fire protecting performance better.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment
