| Model NO. | PGGLA Series Pluggable Lightning Arresters |
| Rated voltage | 10kV |
| Series | PGGLA Series |
Overview
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.
Features
Touch-safe and easy to install
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.
Excellent Insulation Performance
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.
Non-flammable and Self-extinguishing Properties
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.
Control and Shielding of Electric Field Intensity
Through reasonable layout and shielding measures, the impact of electric field intensity on equipment and systems is reduced.
