AI Technical Summary

⚠Technical Problem

The installation method of surge arresters for traditional power transmission towers is easily affected by wind and rain, which can lead to loose bolts and corrosion, affecting the stability of the installation.

⚗Method used

The system employs a positioning groove and a limiting mechanism. By cooperating with the positioning block and the positioning groove, and combining the threaded engagement of the limiting post and the threaded rod, a stable connection between the surge arrester and the mounting bracket is achieved. The drive mechanism using multi-stage bevel gears and internal hexagonal bolt heads improves installation stability.

🎯Benefits of technology

This improves the installation stability between the surge arrester and the mounting bracket, prevents the positioning block from coming off, and ensures the stability of the surge arrester in windy and rainy environments.
