Abstract

The utility model discloses a high-strength insulated heat-insulation cable which comprises main conductors, control conductors and a four-point-star-shaped rubber skeleton. An outer side of each main conductor and an outer side of each control conductor are respectively covered by a butyronityile polyvinyl chloride insulation layer and a fine steel wire armored fireproof layer. The two main conductors are twisted and then covered by a glass fabric wrapping layer to form a main core. The main core is disposed at the central position of the four-point-star-shaped rubber skeleton. Four obtuse-angle gaps outside the four-point-star-shaped rubber skeleton are respectively provided with an elliptical rubber skeleton. Each elliptical rubber skeleton is internally provided with one control conductor. An outer side of the four-point-star-shaped rubber skeleton is sequentially covered by an aluminium strip armored layer, a flame-retardant wrapping layer, a heat-insulation layer and an oversheath. The high-strength insulated heat-insulation cable adopts the four-point-star-shaped rubber skeleton, is high in anti-compression capability, adopts the flame-retardant wrapping layer and the heat-insulation layer to guarantee a good fireproof heat-insulation performance, is compact and novel in structure, and has good properties of cable flexibility, mechanical strength, water resistance, wear resistance, corrosion resistance and ageing resistance.

Description

The heat insulation cable of a kind of high-strength insulating

Technical field

The utility model relates to cable technology field, relates in particular to the heat insulation cable of a kind of high-strength insulating.

Background technology

At present, all need to use cable, and high temperature brings infringement can to long-time cable in hot environment, easily makes cable accelerated ageing in a lot of high temperature place, existing cable cannot well completely cut off the impact that outside hot environment is brought to cable.

Utility model content

The utility model object is exactly the defect in order to make up prior art, provides a kind of high-strength insulating heat insulation cable.

The utility model is achieved through the following technical solutions:

The heat insulation cable of a kind of high-strength insulating, include leading body, control conductor and four jiaos of rubber spider skeletons, outside at described leading body and control conductor is coated with respectively butyronitrile polyvinyl chloride insulation layer and LWA light wire armoured flame retardant coating successively, form master core by being surrounded by glass-fiber-fabric lapping layer after stranded two leading bodies, center at four jiaos of rubber spider skeletons is placed with master core, in the space, four obtuse angles, outside of four jiaos of rubber spider skeletons, be placed with respectively oval rubber skeleton, all be placed with described control conductor in each oval rubber skeleton inside, be coated with successively aluminium strip lock armo layer in the outside of four jiaos of rubber spider skeletons, fire-retardant belting layer, thermal insulation layer and oversheath.

The utility model has the advantages that: the utility model uses four jiaos of rubber spider skeletons, anti-pressure ability is strong, and fire-retardant belting layer and thermal insulation layer have guaranteed good fire insulation performance, compact conformation novelty, cable pliability, mechanical strength, waterproof, wear-resisting, corrosion-resistant, ageing resistace is strong.

Accompanying drawing explanation

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

Embodiment
