High-performance aluminium alloy cable for building

Abstract

The invention discloses a high-performance aluminium alloy cable for buildings, which solves the problems that the conventional power cables for buildings consume more copper resources, are worse in bending performance, and have short service life and the like, and has the advantages of light weight, the capability of corrosion-resistance and halogen-free flame retardant, small bending radius, excellent electrical property, long service life and the like. The high-performance aluminium alloy cable structurally comprises a cable core, wherein the cable core is formed by a plurality of wire core conductors arranged inside a filler and made of aluminium alloy; a conductor double-layer insulation layer is arranged on the outer wall of each wire core conductor; the plurality of wire core conductors are intertwisted in a symmetric arrangement manner; the outer wall of the filler is wrapped with a cable belting layer, a cable armored layer and a cable shield layer sequentially from the inside out.

Description

technical field [0001] The invention relates to an aluminum alloy cable, in particular to a high-performance aluminum alloy cable for construction with a designed service life of 70 years. Background technique [0002] At present, the cables commonly used in buildings are mostly copper and aluminum conductors. Under the environment of increasing consumption of copper ore resources, the cable industry has been expecting to develop a conductor that can continue to promote the use of aluminum instead of copper, aiming at pure aluminum as a cable conductor There are many shortcomings, developed countries such as Australia and Canada have developed aluminum alloy conductors. The safe service life of cables for construction is generally designed to be 30 years, which cannot match the standard of 70 years for the average life of buildings. Under normal circumstances, the wires and cables in the building are replaced every 30 years, and each replacement involves thousands of househo...

AI Technical Summary

Problems solved by technology

This kind of aluminum alloy for construction uses aluminum alloy as the conductor material, but its structure has not yet broken through the conventional power cable form. It adopts single-layer insulation and single performance, and the design service life of the building is not less than 70 years. The design service life has not yet broken through, and it still cannot match the design service life of the building. Therefore, the cables still need to be replaced two to three times during the service life of the building. During this period, the replacement cost is huge, and the project is cumbersome, resulting in a great consumption of manpower and material resources.
