High gradient oxide resistors have good Nonlinear characteristics, large flux, low residual voltage, fast response time and no freewheeling. the application of high potential gradient resistors in Line lightning protection will reduce the number of resistors, so that the Volume and weight of the lightning protection device are greatly reduced, which Is conducive to its installation in the line;

the high gradient lightning protection Device with series gap can greatly improve the long-term working conditions of the valve plate and improve the power supply reliability of the power grid.

the new high-gradient lightning protection Device with series gap is small in size and light in weight, easy to install, and at the same time, it can protect the insulator from damage, and can Effectively reduce the trip rate of lightning strikes.
