Substitute become more and more important instantly international situation and resource are more nervous.And aluminium alloy cable is since appearance
Just to there is the advantages parts such as at low cost, light-weight, corrosion resistance is strong, security performance is high instead of conventional copper cable.Although at present
The market share that copper wire cable is still in the great majority, but this can not cover the trend of aluminium alloy cable market share rising.
However aluminium alloy cable still there are resistivity it is high, current-carrying capacity is small, heating temperature is high the deficiencies of.In same sectional area
In the case where, the conductivity of aluminium alloy is the 61.8% of the most frequently used reference material copper IACS, and current-carrying capacity is the 79% of copper.Therefore,
The resistivity for further decreasing aluminium alloy cable becomes urgency instantly.Stone big science and technology petrochemical industry Co., Ltd Jia Ke in Shandong is in " section
Skill technical application " entitled " aluminium alloy cable, aluminium cable, copper cable techno-economic comparison " has been delivered, describe company A
Resistance value is 0.8480, that is to say, that this cable sacrifices aluminium by adding a small amount of metallic elements such as copper, iron, magnesium in fine aluminium
Electric conductivity, exchange the raising of its mechanical performance for.In addition, aluminum-alloy conductor material in the prior art, in electrical property, corrosion-resistant
Performance and mechanical performance etc. are more excellent, but in terms of anti-fatigue performance or poor, to be easy to appear quality
Problem influences the service life of aluminum alloy materials or brings security risk, therefore, aluminium alloy power cable comprehensive performance still compared with
Difference.
