Steel stranded cable with aluminum is a kind of bimetallic wires. The aluminum is covered on the steel core continuously and uniformly. The conductor has many advantages, such as good electric conductivity, anticorrosion, high frequency transmission, high strength of steel and so on. 

The steel stranded cable with aluminum is the core of the Concentric-lay-Stranded Aluminum Conductors Aluminum Conductors Aluminum-Clad Steel Reinforced. And the Concentric-lay-Stranded Aluminum Conductors Aluminum Conductors Aluminum-Clad Steel Reinforced is made of the steel stranded cable with aluminum and the aluminum wire. So compared with the ordinary conductor, the weight of the conductor is 5% lighter, the current-carrying capacity is 2-3% higher, the wastage of the electricity is lower, the useful life is longer, and the cost is lower. It is widely used on the electric transmission line, especially the line in coastal city, saline, and polluted industrial areas. It also widely used on the conductor whose percentage of aluminum and steel need to be enlarged.

Steel stranded cable with aluminum can be divided into 20AC、23AC、27AC、30AC、33AC、40AC, according to its electric conductivity. And the corresponding conductivities are 14% 20.3%、23%、27%、30%、35% and 40%. (ASTM Standard)

The code name of the steel stranded cable with aluminum is LBGJ, JLB,ACS
