Main application
For high-voltage transmission lines, due to the limited path of the line, it is impossible to erect multiple lines on one path. People have come up with the idea of using one path, one set of iron towers, and hanging multiple wires, that is, one line is equivalent to erecting multiple lines. Line method; for 500KV transmission lines, most of our country adopts the method of hanging four wires. This method of wiring is called paralleling on the same tower
