Mechanical structure
Adopting single-column double-lever structure, with split design for moving and fixed contacts, resulting in low contact resistance;
Coating treatment of conductive components to improve corrosion resistance; The grounding circuit uses aluminum alloy conductive rods and soft connections, with high reliability;
Waterproof bearing seat design, open standard stainless steel material to reduce the risk of corrosion
Application scenarios
- Isolation and maintenance equipment for substations/power plants to ensure the safety of operating personnel
- The power distribution system cooperates with circuit breakers to achieve control of the power outage process (opening the circuit breaker before power outage, and closing the isolation switch before transmitting power)
Switching high-voltage lines during idle conditions to optimize power system performance
The GW4 Series 220kV disconnector combines the safety, durability and ease of maintenance of high voltage systems through design optimization and material upgrades.
