What are the Reasons for Choosing Steel-Cored Aluminum Stranded Wires for High-Voltage Transmission Lines?

Why use steel core aluminum stranded wire for high-voltage power transmission? Isn't the stability and reliability of power cables relatively high? Moreover, the steel core aluminum stranded wire uses bare wires without insulation as the conductor. Let's listen to what China Cable Supplier has to say.

Aluminum Conductor Steel Reinforced Cable

For high-voltage power transmission, bare wires are usually used. Because when the voltage reaches 10 kV, the 30mm thick rubber insulation has lost its function and is easily broken down by high voltage. Steel core aluminum stranded wire has low investment, simple construction, and convenient maintenance and repair, which are also factors in choosing overhead cables; on the contrary, the budget cost of power cables is too high.

Steel core aluminum stranded wire for high-voltage power transmission is due to the low density of aluminum; in the case of equal volume, the mass of aluminum is smaller than that of iron and copper, and the conductivity is better than that of iron. Flow along the surface of the wire.

Aluminum Conductor Steel Reinforced Cable is made of steel wire in the middle and aluminum wire on the outer edge; the reason for using the steel core is that the strength of aluminum is not good, the quality is soft, and it is easy to break. The use of a steel core can increase the strength of the wire without affecting the conductivity.
