Abstract

Disclosed in the utility model is an insulated ultra-flexible wire cable for aerospace. The cable comprises aluminum conductors, a belting layer, a chloroprene rubber sheath layer, a silver-plated copper wire armor layer, a semi-conductive filler layer, an aluminum tape armor layer and a butyronitrile insulation layer. According to the cable, seven groups of conductor cores are arranged; and each group of conductor cores are formed by stranding of seven aluminum conductors. The outside of the seven groups of conductor cores is coated with the belting layer; the outside of the belting layer is coated with the chloroprene rubber sheath layer; the outside of the chloroprene rubber sheath layer is coated with the silver-plated copper wire armor layer; and the outside of the silver-plated copper wire armor layer is coated with the semi-conductive filler layer. According to the scheme, the outermost layer is the butyronitrile insulation layer. The provided cable is especially suitable for the fields of spaceflight and ship and the like and has characteristics of excellent electrical property, good acid-base resistance property, high tear growth resistance, high magnetic force interference resistance, and good heat resistance; and the excellent electrical and mechanical performances can be maintained in the severe environment.

Description

The super soft electric wire of insulation for a kind of Aero-Space

Technical field

The invention belongs to field of cables, relate in particular to the super soft electric wire of a kind of Aero-Space insulation.

Background technology

At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in field of aerospace, useful life to cable, electric conductivity, mechanical performance, coercive force disturb, the requirement of acid-proof alkaline aspect is all high especially, only meet the requirements, the fail safe could improve the manufacturing in these fields time.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of electric conductivity strong, anti-tear drawing property is strong, the super soft electric wire of insulation for Aero-Space that shielding properties is excellent.

The present invention takes following technical scheme to realize: the super soft electric wire of insulation for a kind of Aero-Space, it comprises aluminium conductor, belting layer, chloroprene rubber sheath layer, silver-gilt copper wire armour, semiconductive packed layer, aluminium strip armour and butyronitrile insulating barrier, this cable conductor cable core has seven groups, every group of conductor cable core is all by seven stranded forming of described aluminium conductor, outside seven groups of conductor cable cores, be enclosed with one deck belting layer, outside described belting layer, wrap up one deck chloroprene rubber sheath layer, outside described chloroprene rubber sheath layer, wrap up one deck silver-gilt copper wire armour, outside described silver-gilt copper wire armour, wrap up one deck semiconductive packed layer, the outermost layer of this cable is butyronitrile insulating barrier.

In described belting layer, be provided with 32 aluminium alloy conductors.

Described silver-gilt copper wire armour inside is provided with steel cable.

Described butyronitrile insulating barrier inside is provided with a copper wire drainage thread.

The present invention has following beneficial effect in sum: the utility model is specially adapted in aerospace field, this kind of cable has superior electrical property, strong, anti-tear the drawing property of resistance to acids and bases is strong, coercive force disturbs and heat-resisting feature, can in rugged environment, keep its superior electric property and mechanical performance.
