One of the most commonly used wires on power lines. It is made of a combination of hard round aluminum wire and galvanized steel wire. Anti-corrosion materials can also be applied on steel core and aluminum wire, called anti-corrosion steel core aluminum stranded wire. It is mainly used in areas where coastal and chemical industries have a severe corrosive atmosphere for wires, which can improve the service life of wires.

In the modern power grid, the ultra-high voltage lines use split conductors, which increases the proportion of the conductors in the line construction. Our company has been able to produce 1400mm2 steel core aluminum stranded wire, which is mainly used as soft busbar of 500KV substation. The outer diameter is 51mm.

Standard

Conforms to the standard GB/T 1179-2008: round wire concentric stranded overhead conductor. (IEC61089, MOD)
