Combining the advantages of various line insulator lightning protection overvoltage protectors at home and abroad, it overcomes the existing technical difficulties. It has the design of fixed protection gap, waterproof, double-layer closure and accurate discharge value. Easy installation, reliable performance, maintenance-free advantages.
It has enough ability to withstand switching overvoltage, effectively avoids the action of switching overvoltage, reduces the voltage limiting element, and greatly prolongs the life of the voltage limiting element. When the line is struck by lightning overvoltage and reaches a certain value, the protector starts to operate, thus preventing the insulated line from being fused at high temperature due to power frequency continuous current, effectively avoiding the power supply accident caused by flashover of short line and insulator caused by lightning overvoltage.
