Network, LAN, for the data communication networks such as telecommunication path net, the information transmission system is all essential part.Traditional
All it is that electric power and communication are separately designed into construction in electric power, the construction of network engineering Project design, that is, is divided into heavy current engineering and light current
Engineering.
It is generally known that the copper resource reserves relative deficiency in China, relies heavily on import, therefore find copper cabling
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 of, 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,
Further decreasing the resistivity of aluminium alloy cable becomes urgency instantly.Stone big science and technology petrochemical industry Co., Ltd Jia Ke in Shandong exists《Section
Skill technology application》Entitled " aluminium alloy cable, aluminium cable, copper cable techno-economic comparison " has been delivered, company A is described
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.
