The utility model has the advantages that as the diameter of the conductor monofilament is reasonably selected, the processing is convenient, and obtained finished cables are fine in flexibility so as to facilitate construction and laying, and the mica tape, the glass fiber tape, the insulation layer and the sheath perfectly secure the copper-clad aluminum single-core flame retardant flexible cable.

Description

The copper coated aluminum uni-core flame-retardant refractory double sheath soft cable

Technical field

The utility model belongs to technical field of electric wires and cables, is specifically related to a kind of copper coated aluminum uni-core flame-retardant refractory double sheath soft cable.

Background technology

Notion for copper cover aluminum, electric wire production firm is not strange, that is exactly the aluminium that the structure that will constitute each conductive monofilament of conductor wire core is processed into outer field copper and internal layer, can save the copper that belongs to strategic resource in large quantities like this, can make the maximum function of copper performance again.For example being no lack of before in the Chinese patent literature at document has report, for example: Chinese patent Granted publication CN2881898 introduce the copper cover aluminum city communication cable, the disclosed copper cover aluminum communication cable of CN2881899, the copper clad aluminum conductor communication cable that CN200979818Y recommends, the copper clad aluminum conductor that CN101060024A is public all or the electric wire of copper covered steel conductor, the bimetallic conductor monitoring type earth cable that CN2829026Y discloses, a kind of high strength copper-coated aluminum electric wire/cable that CN2906844Y discloses, also just like CN1758384Y, CN201004349Y, CN2919466Y, CN101086906Y, CN200986831Y, CN2348466Y, CN2904222Y, CN200976298Y, CN200969249Y, CN2891231Y, CN2879357Y or the like has all related to aluminium conductor has been coated copper clad outward, and purpose all is in order to save the copper resource.

But, above-mentioned arbitrary patented technology scheme all not to the conductor structure that constitutes by copper cover aluminum for example diameter disclose, and the applicant thinks, can diameter that the reasonable selection conductor can produce bigger influence for the serviceability of finished cable, for example when diameter is excessive, cable is hardened, be unfavorable for laying; Otherwise too small when diameter, then easily broken the and difficulty of processing of conductive monofilament enlarges markedly, even can't process at all.

Summary of the invention

Task of the present utility model be to provide a kind of flexibility excellent and help laying, handling ease and copper coated aluminum uni-core flame-retardant refractory double sheath soft cable safe in utilization.

Task of the present utility model is finished like this, a kind of copper coated aluminum uni-core flame-retardant refractory double sheath soft cable, it comprises conductor wire core 1 and is positioned at conductor wire core 1 mica tape 2 outward successively, glass fiber tape 3 and insulating barrier 4, outside described insulating barrier 4, also be provided with restrictive coating 5, described conductor wire core 1 constitutes by conductive monofilament 11 is stranded, every conductive monofilament 11 is made of aluminium conductor 111 and the copper clad 112 that are coated on outside the aluminium conductor 111, the diameter of described conductive monofilament 11 is 0.2～1.2mm, wherein: the diameter of aluminium conductor 111 is 0.18439～1.1063mm, and the thickness of copper clad 112 is 0.007805～0.04685mm.

The sectional area of conductor wire core 1 described in the utility model is 1.5～500mm ²

The material of insulating barrier 4 described in the utility model is a low-smoke halogen-free polyolefin.

The material of restrictive coating 5 described in the utility model is a low-smoke halogen-free polyolefin.

The utility model has been owing to made choose reasonable to the diameter of conductive monofilament 11, and is therefore not only easy to process but also make resulting finished cable have good flexibility and be convenient to construction and lay; Mica tape 2, glass fiber tape 3, insulating barrier 4 and sheath band 5 can play good safety effect.

Description of drawings
