مفتاح فصل الجهد العالي GW1 12kV 12kV

The GW1-12G(D) outdoor disconnect switch adopts a double-column vertical opening structure and is suitable for outdoor power distribution networks with rated voltage up to 12kV and frequency of 50/60Hz. It is widely used in:

• substations,
• overhead distribution lines,
• transformer isolation systems,
• industrial power distribution networks.

The switch can be equipped with:

• manual operating mechanism,
• motorized operating mechanism,
• grounding switch (“D” type),
• anti-pollution insulation design.

The “D” model includes an integrated grounding knife switch for enhanced maintenance safety.

Main Features

• Rated voltage: 12kV
• Outdoor installation type
• Double-column vertical break structure
• Visible isolation gap
• Manual or motorized operation
• Optional grounding switch
• Reliable mechanical interlocking
• Strong anti-pollution capability
• Suitable for harsh outdoor environments
