Steel-core aluminum stranded wire, a conductor designed for overhead power transmission lines, is finely twisted with aluminum wire and steel wire. The hard core inside is the steel core, which is responsible for enhancing the overall strength, while the aluminum stranded wire is tightly wound on the outside, which is mainly responsible for transmitting electrical energy.
In high-voltage power transmission lines, due to the limited line corridor and the inability to set up multiple lines on a single corridor, engineers have cleverly proposed a solution: under the same path, use a set of iron towers to hang multiple conductors, so that one line has the function of multiple lines.
Steel-core aluminum stranded wire has become an ideal choice for overhead power transmission and distribution lines with its simple structure, convenient installation and maintenance, low line cost, and excellent conductivity and mechanical strength. It has a large transmission capacity and is particularly suitable for laying across complex geographical environments such as rivers and valleys. At the same time, it has high tensile strength and the tower pole distance can be flexibly adjusted, which further broadens its application range.
