Technical field
The utility model relates to a kind of cable, specifically refers to a kind of rare earth aluminium alloy flame-retardant low-smoke halogen-free metal linkage armored cable.
Background technology
From the seventies in last century, aluminium alloy cable has started a large amount of uses in industry and civil buildings abroad, and the current big country of China's and copper scarcity of resources abundant as bauxite resource has but limited the use of aluminum cable in a lot of buildings place.
Along with the development of advancing by leaps and bounds of power industry, the demand of cable just increases progressively with 10～15% annual growth.Now wires and cables industry wire used is mainly copper and aluminium, because copper valency is soaring at a high speed, in order to reduce producing cost, world's wires and cables industry propose to using aluminium for copper the method as electric wire wire.At present, China's aluminium production capacity surplus, meanwhile, the breach of copper material is large needs import, in order to change the dependence to copper material, makes full use of Domestic Resources, guarantees that the key of power industry sustainable development is to widely popularize aluminium as the wire of electric wire.In cable industry, aluminium is the ideal material that replaces copper, but fine aluminium wire exists again some shortcomings as: bad mechanical strength, easily creep, easily overload heating etc.
The wire diameter of conventional aluminium leader cable is larger, and steel-tape armouring level of security is low, and when being subject to extraneous destructive power, its defensive ability/resistance ability is poor, easily causes puncturing, and Heavy Weight, and installation cost is quite high, poor corrosion resistance in addition, and useful life is not long.This common cable structure, cannot in adverse circumstances, move for a long time, and processing is more complicated and difficult.Under normal circumstances, existing cable can meet the demands, if but cable be used in adverse circumstances and cable security required, in higher environment, can not to meet instructions for use.
