Abstract

The utility model discloses an electric power shielding cable having a simple structure. The electric power shielding cable comprises main conductors and control conductors, wherein outer sides of the main conductors and the control conductors are respectively wrapped in a fluorine plastic insulation layer, the multiple control conductors are stranded, an outer side of the stranded control conductors is sequentially wrapped in a glass fiber braiding layer, a fine steel wire armored fireproof layer, a silicon rubber insulation layer and a PTFE wrapping layer to form a wire core, two wire cores are placed in upper and lower arc spaces of an S-shaped rubber framework, the two main conductors are respectively placed at left and right sides of the S-shaped rubber framework, and an outer side of the S-shaped rubber framework is sequentially wrapped in a butyronitrile polyvinyl chloride insulation layer, a zinc-coated steel belt wrapping armored layer and a dual-steel-belt armored polyvinyl chloride outer sheath. According to the electric power shielding cable, the two wire cores are placed in the upper and lower arc spaces of the S-shaped rubber framework, the two main conductors are respectively placed at the left and right sides of the S-shaped rubber framework, so strength of the cable is improved, the cable is not liable to damage, service life is prolonged, and the fireproof effect is good.

Description

A kind of shielding power cable simple in structure

Technical field

The utility model relates to cable technology field, relates in particular to a kind of shielding power cable simple in structure.

Background technology

Some are used in cable in specific environment needs the characteristics such as cable core softness, resistance to twisting property are strong, tension, and Structure of need is simple, lightweight, to prevent that cable from use rupturing, affects work, causes a large amount of wastings of resources.

Utility model content

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

The utility model is achieved through the following technical solutions:

A kind of shielding power cable simple in structure, include leading body and control conductor, all be surrounded by fluoroplastic insulation layer at described leading body and control conductor outside, outside after multiple control conductor bundle strands is surrounded by fiberglass braided layer successively, LWA light wire armoured flame retardant coating, silica gel thermal insulation layer and polytetrafluoro lapping layer form core, two cores are placed in the arc space up and down of S shape rubber skeleton, two leading bodies are placed on respectively to the left and right sides of S rubber skeleton, be coated with successively butyronitrile polyvinyl chloride insulation layer in the outside of S shape rubber skeleton, the wrapped armour of galvanized steel strip and double-tape armor polyvinyl chloride oversheath.

The utility model has the advantages that: the utility model is placed on two cores in the arc space up and down of S shape rubber skeleton, two leading bodies are placed on respectively to the left and right sides of S rubber skeleton, have strengthened the intensity of cable, be not easy to damage, extended useful life, flameproof effect is good.
