1. Features and USES of aluminum alloy wire:
Aluminum alloy density is low, but the strength is relatively high, close to or more than high quality steel, good plasticity, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, usage is second only to steel.
Because the strength of aluminium alloy is high, weight is light, when making strand, have more advantage, compare with the steel core aluminium strand of same performance, its diameter can be a little bit smaller, compare with aluminium strand, the gear distance of transmission line can increase.
Because of its many advantages, it has been paid much attention by people in power systems of various countries.
High strength aluminum alloy wire mainly with large span transmission, heat-resisting aluminum alloy conductor is solved the wire because of increased load flow temperature rises, under the condition of high temperature (150 ℃), the conductor is not significantly reduced performance, but its low strength itself, has weakened the line has a high strength aluminum alloy is a little bit, high strength heat resistant aluminium alloy conductor is changed this situation, namely under high temperature condition still keep good high strength, which is greater than 90% survival rate after heating value to achieve high strength.
