　　Advantages of steel cored aluminum stranded wire:

　　 The advantage of steel cored aluminum stranded wire is that it has a simple composition, but it has powerful functions and can be used on high voltage electrical frames to ensure the normal operation of voltage output. Some places have unique geographical conditions, such as stranded wires on long rivers and high mountains that can maintain a large span without breaking. The emergence of stranded wires reduces the difficulty of installing high-voltage electrical racks. If there is strong wind, there is no need to worry about them being pulled, and they can be used for a longer time in harsh environments, ensuring that maintenance and replacement are not required for a long time. The production cost of twisted wire is relatively low, which can save a significant portion of installation costs. Another important advantage is that it can carry large voltage and current loads. If high-intensity current output is required, the stranded wires can be concentrated together to increase the propagation force and speed, helping to output electricity in situations with high electricity consumption.

　　 Steel cored aluminum stranded wire is made by twisting aluminum wire and steel wire, and is suitable for overhead transmission lines. Its interior is a steel "core", and the exterior is wrapped around the steel core with aluminum wire twisted together. The steel core mainly increases strength, while the aluminum wire mainly transmits electrical energy.
