Aluminum clad steel strands

Aluminum clad steel strands is produced by way of concentric stranding the aluminum clad steel wires of the same or different conductivity according to certain structure, specified lay ratio,with higher mechanical strength and corrosion resistance,mainly used in overhead transmission field of power system. The aluminum clad steel strands series products of our company includes aluminum conductor aluminum clad steel reinforced-ACSR/AW for power transmission line.

Aluminum clad steel strands for long-stride, aluminum alloy conductor aluminum clad steel reinforced for long-stride, thermo-resistance aluminum alloy conductor aluminum clad steel reinforced for high current carrying capacity,aluminum conductor aluminum clad steel reinforced,aluminum alloy conductor aluminum clad steel reinforced,etc.The structure and approximate parameters of aluminum clad steel strands with different conductivity see table 2
