The Function of Aluminum Core Steel Wire (ACSR) in the Power Industry

Understanding Steel-Core Aluminum Stranded Wire

Steel-core aluminum strand (ACSR)  plays a vital role in the power industry. We absolutely can not ignore the electricity it, because it can transport electricity. Because of the power supply, our life has become more beautiful. For example, electric lights and computers work through electricity, so it's hard to imagine to can't imagine an afterlife without electricity.

In this modern era of advanced science and technology, many industrial modernization facilities have appeared in our life. Aluminum-stranded wire with steel core (ACSR) is also a mainstay in the power sector. Aluminum stranded wire with steel core (ACSR) is a reinforced wire with single or multiple layers of aluminum strands stranded outside a galvanized steel core. The power and transmission line industry can use it.

Why steel-core aluminum stranded wire for high-voltage transmission?

 Steel-core aluminum-stranded wire (ACSR) is made of aluminum and steel wires stranded together and is suitable for overhead transmission lines. It has an internal steel "core" and an external aluminum wire wrapped around the steel core. The steel core serves mainly to increase the strength of the aluminum strand.

 The high-voltage transmission uses steel-core aluminum-stranded wire, but the line is limited, and it is impossible to put more than one line on a path. So people came up with a road, a set of towers, and the method of hanging multiple lines. In other words, a line equivalent to multiple lines - 500kv transmission lines.

For high voltage transmission, we always use bare wire. Because electrons are moving on the metal of the surface, The high voltage thick rubber will break through the insulation skin.

The metals with high to low conductivity are silver, gold, copper, and aluminum. We don't use silver, gold, or copper for electric transportation because the cost is too high. So we choose metallic aluminum. The reason is that the density of aluminum is small, and the mass of aluminum is smaller than iron and copper in the same volume. Electrical conductivity is also better than iron. However, aluminum is softer and not strong enough. Therefore, the steel-core aluminum-stranded wire has commonly used in the industry to ensure its robustness and conductivity.

Steel-core aluminum strand (ACSR) has the following advantages: simple structure, easy to erect, low maintenance cost, low line cost, large transmission capacity, and can be used in various complex geographical areas.
