Sulfur hexafluoride enclosed type gapless metal oxide surge arrester (GIS surge arrester) is used for 66kV to 500kV gas-insulated metal sealed switchgear to protect its insulation from overvoltage damage.
High-speed railway gapless metal oxide surge arresters are primarily used in high-speed railway systems.
The porcelain-housed lightning arrester uses a porcelain bushing as the external insulation, with a single-column or multi-column resistor disc column as the core.
The polymer-housed lightning arresters feature a polymer and composite material housing, with a single-column or multi-column resistor disc column as the core.
