Abstract
The present invention is a copper-aluminium composite inner conductor, which relates to a communication material, particularly a signal transmission cable including copper layer and aluminium layer, said aluminium layer is an aluminium tube with hollow structure inside, said copper layer is a copper tube enclosing outside the aluminium tube. The preparation steps includes: cleaning and aligning copper belt and aluminium tube, coating and welding the copper belt, drawing a composite tube. The cable inner conductor reduces raw material and cost.
Description
Technical field:
The present invention relates to a kind of communication material, especially a kind of signal-transmitting cable is copper-aluminum compound conductor specifically.
Background technology:
The telecommunication cable inner wire is to use pure copper wire always, after the nineties, because the finiteness of nonferrous metal resource, in order to save the consumption of copper resource, begin to research and develop the composite material cable abroad, to save the consumption of copper, common is copper aluminium composite cable, still, along with shortage of resources, the price of aluminium goes up significantly, becomes raw material in short supply gradually, causes the production cost of copper aluminium composite cable manufacturing enterprise also to increase substantially, so, improve product structure and production method, reduce whole raw-material consumption, cost becomes a kind of needs that cable is produced.
