The GW4 series outdoor AC disconnector is suitable for power systems with rated voltages of 12-40.5kV and 50Hz frequency. Composed of isolating blades, grounding blades, and operating mechanisms, it features clearly visible isolation gaps to disconnect high-voltage maintenance equipment from live parts. The grounding blade effectively prevents misoperations such as "energizing grounded lines" or "closing on grounded lines." This product is characterized by its simple structure, high safety and reliability, and cost-effectiveness, making it widely used in distribution systems.

The product performance complies with:

GB1985-2014 High-voltage Alternating Current Disconnectors and Earthing Switches

GB/T11022-2020 Common Specifications for High-voltage Alternating Current Switchgear and Controlgear

IEC 129 Disconnectors and Earthing Switches
