GW4 Isolation Switch 126-138kV Isolation Switch (also known as Disconnector)
Used for line isolation, equipment maintenance, or power system switching during no-load conditions, cannot interrupt loads or fault currents and must be used in conjunction with circuit breakers.
GW4 Isolation Switch 126-138kV Isolation Switch (also known as Disconnector)
Used for line isolation, equipment maintenance, or power system switching during no-load conditions, cannot interrupt loads or fault currents and must be used in conjunction with circuit breakers.
Can be configured with single- or double-ended ground switches (eg GW4-126D/DW type) to achieve isolation between the main circuit and ground.
Typical Application Scenarios
- High-voltage power lines: 126 kV substation bus segmentation, transformer neutral point isolation and line open-circuit switching.
- Isolation when servicing equipment: When servicing and switching off power to the circuit breaker are combined, visible electrical break points are created.
- Industrial power systems: insulation and protection of high-voltage distribution systems in large industrial and mining plants.
The 126kV GW4 isolation switch, with its modular design, high reliability and ability to adapt to difficult environments, has become the core equipment for the safe operation and maintenance of high-voltage power grids. When choosing, you should focus on the current power, grounding configuration and compliance with the pollution level.
