| Series | PGGLA Series |
Shielded plug-in surge arresters are suitable for C-GIS switchgear, gas-insulated ring-main units, and oil-immersed transformer protection in power systems up to 35kV. The external design uses a fully shielded metal housing, while the internal components utilize imported liquid silicone rubber material.
The anti-electric shock enclosure and double-layer insulation design measures ensure touch safety, and the simple plug-and-play operation is convenient and quick.
High-performance insulation materials are adopted, and through reasonable layout and sealing measures, the overall insulation performance of the lightning arrester is ensured to be reliable.
When exposed to external factors such as fire sources, the material will not continue to burn or spread the fire, but will extinguish itself within a certain period of time.
Through reasonable layout and shielding measures, the impact of electric field intensity on equipment and systems is reduced.
