Construction Technology of 110 kV Overhead Transmission Line Crossing Expressway

The article takes a 110 kV transmission line B34-B35 crossing the Shankun Expressway project as an example to design a special scheme for large-span grid sealing and stringing. According to the on-site environment and technical indicators, conduct network blocking calculation and cross protection. Cooperate with unmanned aerial vehicles and pulley traction ropes to automatically suspend and release wires. It not only reduces operational risks but also shortens the construction cycle, resulting in significant practical benefits.
