Problems solved by technology

In the prior art, many use pure copper as the conductor. Although this can improve the conductivity of the conductor, it also reduces the mechanical properties of the cable while improving the conductivity. Therefore, the two are a contradiction.

Abstract

The invention discloses a high-conductivity copper-clad aluminum cable which comprises an aluminum alloy core. The aluminum alloy core comprises 0.1-1.5% of Cu, 0.02-0.1% of Be, 0.2-0.8% of Mg and the balance Al. A skin layer is made of pure copper, and the pre-heated skin layer warps a core layer under argon protection; a tin layer is sprayed on the surface of the skin layer, and then a silver layer is sprayed on the surface of the tin layer; the surface of the silver layer is wrapped with a layer of silver-plated fiber net, and finally an insulating layer and a protecting sleeve warps the outer portion of the silver-plated fiber net in an extrusion manner. First Be is added into aluminum alloy, and conductive performance of the aluminum alloy is greatly improved; in addition, the conductive performance is more outstanding due to the wrapping of continuous multi-layer conductive layers, and due to the wrapping of the silver-plated fiber net, the conductive performance is also enhanced while shielding effect is achieved; in addition, copper skin wraps the aluminum alloy, the pure copper skin layer also guarantees toughness of the cable while the strength of the core layer is guaranteed, and mechanical performance is greatly improved.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a high-conductivity copper-clad aluminum cable. Background technique [0002] As a transmission medium, the most important thing for cables is to transmit electric energy, but resistance is the most important factor affecting the efficiency of cable electric transmission. In the prior art, many use pure copper as the conductor. Although this can improve the conductivity of the conductor, it also reduces the mechanical performance of the cable while improving the conductivity. Therefore, the two are a contradiction. Therefore, it is necessary to develop a new type of cable, replace copper with aluminum alloy, and improve the electrical conductivity and mechanical properties of the cable. Contents of the invention [0003] In order to solve the above problems, the present invention aims to provide a high-conductivity copper-clad aluminum cable, which greatly improves the electric...
