GW1 24kV High Voltage Disconnect Switch

The GW1-24 series outdoor disconnect switch adopts a double-column outdoor structure with three-phase linkage operation. It is suitable for outdoor installations in:

• substations,
• distribution lines,
• transformer switching stations,
• industrial power systems,
• renewable energy distribution networks.

The switch is designed to:

• isolate energized circuits without load current,
• provide visible disconnection for maintenance,
• improve operational safety,
• support manual or motorized operation.

Optional versions include:

• grounding switch type,
• anti-pollution type,
• motor-operated type,
• porcelain or polymer insulator type.
