Indoor high-voltage compressed gas load switch
Product Description
| Product Overview |
| FKN12-12 indoor high-voltage compressed gas load switch (hereinafter referred to as FKN12-12 load switch) is a three-phase high-voltage switchgear with a rated voltage of 12V and a rated frequency of 50Hz or 60Hz, which is used to separate load current, closed-loop current, no-load transformer and current charging current, and close short-circuit current. A load switch equipped with a grounding switch can withstand short-circuit currents. |

| Product Features |
1.Core Functions
- Safely switches load currents, closed-loop currents, no-load transformers, and cable charging currents, with short-circuit current closing capability.
- Equipped with an earthing switch to withstand short-circuit current impacts, enhancing system safety.
|
2.Structural Advantages
- Compact gas-insulated design with high protection grade, adaptable to harsh environments (e.g., humidity, contamination).
- Modular construction compatible with fuse combinations (FKRN12-12 type) for rapid short-circuit interruption and equipment protection.
|
3.Safety & Reliability
- Excellent insulation: 75kV lightning impulse withstand voltage and 42kV power frequency withstand voltage (1 minute).
- 10,000-operation mechanical lifespan with stable performance and minimal maintenance.
|
4.Applications
- Ideal for ring main power supply, compact substations, industrial power distribution, and scenarios requiring frequent operations.
|
5.Customized SolutionsTailored to client requirements
Customization options include rated current adjustment, operating power specifications (AC/DC voltage), and installation configurations.Extended capabilities: Integration of intelligent monitoring interfaces or additional protective modules based on specific operational needs.
