Functional characteristics
Used to form visible break points when isolating a circuit or servicing under no-load conditions, cannot interrupt load current or short circuit current.
Support ground switch (such as GW4-40.5DW type) to achieve synchronous operation between the main circuit and the ground circuit
Typical Application Scenarios
- Substation insulation: used for insulating incoming and outgoing lines of 35 kV substations, bus segmentation and grounding of transformer neutrals.
- Electrical distribution system maintenance: When servicing a circuit breaker, disconnect the power to create a physically visible break point.
- Adapt to harsh environments: Anti-corrosion type (GW4-40.5DW) is suitable for high pollution areas such as salt fog and humidity.
The 40.5kV GW4 isolation switch has become the core equipment for safe isolation in medium voltage power systems due to its high strength mechanical design and optimization of high conductivity materials. When choosing, you should focus on the rated current, operating mode and suitability to the environment.
