A complete high-voltage pole tower looks like this:
The bottom is the pedestal, and some have pull wires, the top is the cross arm, the line is suspended by the cross arm through the insulator string, and the top is the communication line and the lightning protection line (by the way, the power communication is detached from the major communication groups in China There is one kind of existence, and there is more than one means. Even if there are no satellites in China, no base stations, and no China Mobile Unicom Telecom Tongtong, dispatching centers and agencies at all levels related to power generation and consumption can continue to communicate. If you destroy one or two communication lines, you cannot block communication, unless you have the ability to master all the communication line diagrams and ask for them to destroy each important node. Tell you where the diagram is? Sorry, this is a secret, and I don't know it either. I know and can't tell you, it's a crime).
There are many shapes of towers. Single-circuit lines generally have a wine glass shape with wires arranged horizontally and a cat-head shape with a triangular arrangement. Double-circuit lines generally use an umbrella shape in the ice-free area, drum shape in the ice area, and in the transmission corridor. In tense and economically developed areas, compact towers with four circuits on the same tower will also be used.
