Abstract
The utility model relates to a copper clad aluminium braided shielded control cable which comprises a conductor, an insulating layer of the conductor, and an outer sheath. The copper clad aluminium braided shielded control cable is characterized in that a wrapping layer and a copper clad aluminium braided shielding layer with braiding density of not less than 80% are sequentially additionally wrapped on the outside of the insulated conductor after forming the cable. The copper clad aluminium braided shielded control cable uses copper clad aluminium to replace pure copper and can save copper resources, and the cost is low; compared with the copper wire shielding layer with the same technical indicators, the cable can save the cost by more than 40%, the weight is light, the cable has the corrosion resistance performance and the weldability which are the same with copper shielding, the production is convenient, and the electrical performances of the cable are in line with the requirements of national standard GB9330-1998.
Description
Technical field
The utility model relates to a kind of control cable, particularly a kind of copper cover aluminum braid shielded control cable.
Background technology
As the electric power transfer secondary protection system; the connecting line of control between each quasi-instrument, instrument, the automatics, monitoring interlock circuit and protection circuit; great majority are to adopt braid shielded type cable at present, and its braid shielded layer material mainly is circular copper wire or zinc-plated circular copper wire.Need to use a large amount of rare copper products, cost height, Heavy Weight.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned weak point, and a kind of good electric property is provided, and saves the copper resource, and cost is low, and is in light weight, the copper cover aluminum braid shielded control cable that corrosion resistance and weldability are good.
The purpose of this utility model is achieved in that copper cover aluminum braid shielded control cable comprises conductor, insulating layer of conductor, oversheath, it is characterized in that outside behind the insulated electric conductor stranding increase successively be wound with belting layer, count is not less than 80% copper cover aluminum woven shield.
The utility model is owing to adopt above architecture advances, replace fine copper with copper cover aluminum, can save the copper resource, cost is low, the copper cash screen cable of comparing constructed index is cost-saved more than 40%, in light weight, under the online footpath of copper-clad aluminum conductor, the equiponderant situation, its length is 2.5 times of pure copper wire.Because copper clad aluminum material is metallurgyization fully, aluminium is covered by copper, reaches and coppery decay resistance.Therefore copper-clad aluminum conductor has the solderability the same with pure copper wire because its surface has coated one deck fine copper with one heart, convenient production, and the electric property of cable meets the requirement of standard GB 9330-1988.
Description of drawings
Fig. 1 is the utility model end face structure schematic diagram.
Embodiment
