A tensile aluminum alloy power cable

Abstract

The invention discloses a tensile aluminum alloy power cable, include an out protective layer, Buffer layer and cable body, A metal armor lay is arranged on that inn side of the outer protective layer, A reinforcement layer is arranged on the inner side of the metal armor layer, a plurality of reinforcement ribs are arranged on the inner side of the reinforcement layer, a shielding layer is arranged on the inner side of the reinforcement layer, an insulating layer is arranged on the inner side of the shielding layer, a buffer layer is arranged on the inner side of the insulating layer, a plurality of support blocks are arranged on the inner side wall of the buffer layer, and a traction wire core is arranged on the inner side center of the buffer layer. In accordance with that present invention, through the outer protective layer, The metal armored layer, the reinforcing layer, the shielding layer, the insulating layer and the buffer layer protect the internal power cable core, and thereinforcing bars arranged inside the reinforcing layer are favorable to improve the tensile resistance of the cable, so that the abrasion resistance of the cable is stronger, and the metal armored layer enhances the protective hardness of the cable, so that the performance of the cable is improved and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a tension-resistant aluminum alloy power cable. Background technique [0002] A cable is a wire made of one or more mutually insulated conductors and an outer insulating layer that transmits power or information from one place to another. The aluminum alloy power cable is a new type of material power cable invented and created by advanced technologies such as AA8000 series aluminum alloy materials as conductors, special roll forming molding wire stranding production process and annealing treatment. It can greatly improve the conductivity and high temperature resistance of aluminum alloy cables. Using aluminum alloy cables instead of copper cables can reduce the weight of cables, reduce installation costs, reduce wear and tear on equipment and cables, and make installation work easier. [0003] At present, the existing power cables are composed of a cable core and a sheath wrapped...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing power cables are composed of a cable core and a sheath wrapped outside the cable core. This kind of power cable has poor tensile strength and shielding performance. Using a copper conductor core is a waste of resources. It will cause the loss of non-renewable resources, increase the production cost, and the total weight of the cable is heavy, which is limited by the length and cannot meet the needs of use.
