Abstract

A flat cable with copper cladding aluminum core nitrile butadience rubber insulation and sheath mainly comprises an aluminium core (1), a copper layer (2), a nitrile butadience rubber insulating layer (3) and a sheath (4). The flat cable is characterized in that: a layer of uniform and high quality copper layer (2) is electroplated out of the aluminium core (1) and in an electrolytic cell so as to form a copper cladding aluminum core (1); the copper cladding aluminum core (1) is wrapped with the nitrile butadience rubber insulating layer (3); the nitrile butadience rubber insulating layer (3) is wrapped with the sheath (4) which is made of a PE material.

Description

Fine insulation of copper-covered aluminum-core fourth and sheath flat cable

?

Technical field

The present invention relates to a kind of cable, specifically relate to fine insulation of a kind of copper-covered aluminum-core fourth and sheath flat cable.

Background technology

Produce cable and always make inner wire with fine copper, the weight of copper accounts for the 70-75% of cable total weight.Under the situation international, that domestic amount of copper consuming is constantly soaring, the copper resource gets over shortage, adds human factor, the copper valency rises violently, high, form a series of rise in price reflections, force cable industry actively to seek new conductor material and come the instead of pure copper cash to make the inner wire of cable.

The conductor that existing cable adopted mostly is the fine copper conductor wire core of multicore or single core softness, and insulating barrier mostly is polyvinyl chloride or other suitable synthetic elastomer composite materials, and cover layer constitutes the double sheath of insulation.As everyone knows, because the density of pure cu conductor is big, cost is high, be difficult for moving: aluminium conductor then exists conductance low, and welding performance is poor, defectives such as the easy oxidation in surface.And its long-term working temperature that allows is restricted its scope of application below 60 ℃.When high-temp combustion, can discharge unpleasant toxic gas, contaminated environment.

Summary of the invention

In view of the defective that prior art exists, the objective of the invention is to provide that a kind of cost performance is higher, applicability is extensive, conduct electricity very well good insulating, fine insulation of copper-covered aluminum-core fourth and sheath flat cable that cost is lower.

For achieving the above object, the technology used in the present invention solution is by the aluminium core, the copper layer, and fine insulating barrier of fourth and sheath are formed, and its major technique feature is the outer surface at the aluminium core, electroplates the high-quality copper layer of layer of even in electrolysis tank, forms copper-covered aluminum-core; Be wrapped with the fine insulating barrier of fourth at copper-covered aluminum-core, be wrapped with sheath at the fine insulating barrier of fourth, sheath is made for the PE material.

Copper-clad aluminum conductor has both the characteristic of two kinds of metals simultaneously, has advantages such as good conductivity, density is little, softness good, processing is simple and easy, unit cost is low; Copper cover aluminum can be saved the copper resource as cable inner conductor, and obviously reduces the material cost of cable, has also reduced the manufacturing cost that cable is produced simultaneously, and the transmission performance of copper-clad aluminum conductor is better simultaneously.

The fine insulating barrier of fourth is abominable for environment for use; the cable of complicated condition; as welding machine cable; not only require insulation, certain thermal endurance is arranged, also require tear-proof, resistance to wear etc.; adopt the fine insulating barrier of fourth; both can reach the effect of protection copper-covered aluminum-core, simultaneously fourth is fine has softness, waterproof, advantage such as wear-resisting, corrosion-resistant, thereby plays the effect and the effect of protection effectively.Sheath is the PE material, can reach the effect of the fine insulating barrier of protection fourth.

Cost performance is higher, applicability is extensive because the present invention has, conduct electricity very well, and good insulating, the characteristics that cost is lower are a kind of new products with promotional value.
