The 12~24kV indoor high-voltage grounding switch is a safety protection device, not an operational switch for interrupting load current.
Primarily installed within high-voltage switchgear, it provides reliable personnel safety grounding for equipment undergoing power-off maintenance.
This earthing switch fully complies with IEC 62271 and GB standards for high-voltage earthing equipment. It operates stably in temperatures ranging from -40℃ to +70℃, with strong resistance to moisture, dust and corrosion.
Suitable for urban power grids, industrial parks, mining areas, infrastructure projects and various outdoor medium-voltage power distribution scenarios.
1. Substation Equipment Earthing: Provides safe earthing protection during maintenance of transformers, switchgear and feeders.
2. Overhead Distribution Lines: Applied in pole-mounted transformers and branch circuits for safe maintenance and operation.
3. Industrial & Mining Power Systems: Ensures safe earthing for medium-voltage power equipment in industrial and mining sites.
For high-voltage 35kV power distribution solutions, we also provide our professional series equipment: 7S-JDKG 35kV SF6 Load Break Switch.
It safely grounds high-voltage circuits during maintenance, discharging residual voltage to ensure a zero-potential working environment.
Yes. The 7S-JDKG series is specially designed for outdoor applications with high weather resistance and protection grade.
