FHY5C series puncture type external gap lightning arresterDetailed product description：

Characteristics of FHY5C series puncture type external gap lightning arrester

1. The lightning arrester adopts high-performance metal oxide resistors, which have good nonlinear volt ampere characteristics, sensitive release of overvoltage, and low residual voltage;
2. The installation bracket is adjustable and can change the height of the lightning arrester, thereby adjusting the discharge gap between the arcing ring and the conductor to meet the coordination with different insulators.
3. The arc ring adopts an open design, which can be directly inserted during the renovation of old lines, making it easy to install.
