Product descriptions from the supplier
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.

17 Common Questions About Power Transformers1 Why must the transformer core be grounded?During normal operation of power transformers, the core must have one reliable ground connection. Without grounding, a floating voltage between the core and ground would cause intermittent breakdown discharge. Single-point grounding eliminates the possibility of floating potential in the core. However, when two or more grounding points exist, uneven potentials between core sections create circulating currents between grounding points, causing multi-poi12/20/2025 -
