Embodiment 1

[0009] Embodiment one, a kind of single-core copper-clad aluminum-core electric wire and cable of the present invention (seeing Fig. 1, Fig. 2), conductive wire core is that the inner core is that aluminum wire is covered with a layer of cylindrical copper skin conductive wire core, has formed copper-clad A wire with an aluminum conductor, a single conductive core is covered with an insulating material layer of polyvinyl chloride or polyethylene or cross-linked polyethylene or rubber. The implementation plan is exactly the same as the production process of ordinary copper core wires, that is, the insulating material is extruded around the copper-clad aluminum conductor through an extruder, and then cooled, rewinded, printed and packaged to become a finished copper-clad aluminum core wire.

Embodiment 2

[0010] Embodiment two, a kind of inventive multi-core copper-clad aluminum-core wire and cable (see Fig. 3, Fig. 4), the conductive core is that the inner core is that the aluminum wire is covered with a layer of cylindrical copper-skinned conductive core, forming a copper-clad aluminum Conductor wire; and the conductive core is the conductive core of two or more copper-clad aluminum conductors parallel to each other or intertwined, and the outer layer of the conductive core of two or more copper-clad aluminum conductors is insulated material layer. There is also a layer of insulating material between two or more copper-clad aluminum conductors that are parallel to each other or intertwined. A single conductive core is covered with an insulating material layer of polyvinyl chloride or polyethylene or cross-linked polyethylene or rubber. The implementation plan is exactly the same as the production process of ordinary copper core wires, that is, the insulating material is extr...

Abstract

The invention uses copper-clad aluminium conductor as conductive wire core whose inner core is aluminium wire and outer is cylinder copper roofing, the conductive wire also can be at least two conductive wire cores of copper-clad aluminium conductor which are parallel or winding with each other, the outer of conductive wire core is covered with insulated layer of PVC or polyethylene or cross-link polyethylene or rubber. The insulated material such as PVC, polyethylene, cross-link polyethylene or rubber is covered around the conductive wire core to produce copper-clad aluminium wire cable. The copper-clad aluminium wire cable possesses the same conductivity as copper core cable with the same specification, weight is light, easy to process, usage is convenient, and copper can be saved for 80% or above, cost of product can be decreased effectively, defects that the surface of aluminium cable is easy to be oxidized, resistance is big, corrosion resistance and machine performance are poor can be avoided.

Description

technical field [0001] The invention relates to a wire and cable with a copper-clad aluminum conductor as a conductive wire core and polyvinyl chloride, polyethylene, cross-linked polyethylene or rubber as an insulating material. Background technique [0002] The copper core PVC insulated wire widely used at present uses copper as the conductive core. my country is a country lacking in copper resources, and a large amount of copper is imported from abroad every year. As a non-ferrous metal with huge demand, the price of copper in the international market is constantly rising. Since the beginning of this year, the spot price has soared from 47,000 yuan per ton at the beginning of the year to 73,000 yuan. Saving copper is not only the need of enterprises to reduce costs, but also a subject of national strategic significance. [0003] Aluminum is a non-ferrous metal whose conductivity is second only to copper. my country has very rich reserves and strong production and proces...
