40.5KV Outdoor Disconnecting Switch

The GW5 series 40.5KV Outdoor Disconnecting Switch is designed for medium and high voltage transmission and distribution networks operating under AC 50Hz conditions. It is widely used in substations and power stations to safely isolate circuits under voltage without load current. The structure adopts a double-column horizontal V-type opening mechanism, ensuring stable electrical clearance and strong mechanical reliability in harsh outdoor environments.

Compared with traditional isolating switches, this 40.5KV Outdoor Disconnecting Switch provides improved wind resistance, enhanced anti-pollution performance, and a more stable contact system, making it suitable for long-term operation in coastal, desert, and high-humidity regions.

Key Design Features

• Double-column V-shaped horizontal opening structure for improved stability
• Modular pole design with high-strength porcelain or composite insulators
• Supports manual and motorized operation modes
• Optional grounding configurations: non-grounded, single-grounded, double-grounded
• Mechanical interlocking system between main blade and grounding blade for safety
• Enhanced corrosion resistance for outdoor long-term service
