Background technique

At present, the laying-out of power transmission lines is done manually by laying out the conductor traction ropes, and the follow-up construction will continue to use one pull and four torque-free steel wire traction ropes.

Coordination becomes more difficult. The live lines that need to be crossed in the path will also cause unsafe factors, and the traditional way of setting out wires can no longer meet the needs of current construction.
