AI Technical Summary

Technical Problem

In the existing technology, the installation of line overvoltage protectors needs to be carried out under live conditions. Especially in remote areas such as mountains and forests, manual climbing and live work is required, which poses a significant risk of electric shock and is inconvenient to install.

Method used

A live-line installation assembly for an overvoltage protector has been designed, comprising a clamping assembly, a lifting sleeve, a socket wrench, and an insulated wire clamp connector. The clamping assembly enables long-distance live-line installation of the overvoltage protector, while the lifting sleeve and socket wrench facilitate safe and efficient installation. The insulated wire clamp connector ensures the stability of the lead wire connection.

Benefits of technology

This enables safe and convenient installation of line overvoltage protectors, reduces installation costs, improves installation flexibility and stability, avoids the use of live-line working vehicles, and ensures the safety and reliability of the installation process.
