Acsr core wire
Acsr core wire
ACSR core wire is also called galvanized steel wire or strand. The galvanized steel strand or strands form the central core of the conductor, the Class A galvanized layer is bright, clean and firm, strong corrosion resistance. The steel core may consist of a single strand or a concentric-stranded cable of 7, 19, 37 with left or right strand.
Appaction of the acsr core wire
The Aluminium Conductor Steel Reinforced has the advantages of simple structure, convenient erection and maintenance, low cost of the line, large transmission capacity, favorable laying of special geographical conditions such as rivers and valleys, good electrical conductivity, sufficient mechanical strength and high tensile strength. The tower rod distance can be magnified and so on. Therefore, it is widely used in various voltage levels of overhead transmission and distribution lines.
Product processes
ACSR fabricated from high fine low-carbon metal wire rod processing, is the product of high excellent low-carbon steel, after drawing molding, pickling rust, high-temperature annealing, hot galvanized and cooling and other tactics processing.
