GW9 12 кВ Открытый высоковольтный разъединитель

The GW9-12 series outdoor disconnect switch is suitable for single-phase or three-phase AC 50/60Hz power systems with rated voltage up to 12kV. It adopts a single-pole structure and is operated manually using an insulated hook rod.

The switch is mainly used to:

• open and close no-load lines,
• isolate high-voltage equipment,
• provide a visible air-gap for maintenance safety,
• support overhead line sectionalizing.

It is widely installed in:

• rural distribution networks,
• pole-mounted substations,
• transformer isolation systems,
• overhead transmission and distribution lines.

Main Features

• Rated voltage: 12kV
• Outdoor installation type
• Single-pole structure
• Visible isolation gap
• Manual insulated hook operation
• Self-locking mechanism
• Compact and economical design
• Anti-pollution type available (GW9-12W/G)
• Suitable for harsh outdoor environments
