GW9 Outdoor HV Disconnector

The GW9 outdoor high voltage disconnector is a robust single-pole isolating switch used in 12kV outdoor power distribution systems. It can safely operate circuits under voltage without load current. Equipped with a fixed pull hook and self-locking device, it allows flexible and reliable operation using an insulated hook rod. The disconnector provides excellent conductivity, mechanical strength, and anti-pollution performance, meeting the requirements of harsh environmental conditions.

• Single-pole structure, compact and durable.

• Fixed pull hook with self-locking device for safe operation.

• Operated with an insulated hook rod, ensuring operator safety.

• Large contact area, low contact resistance, excellent conductivity.

• High mechanical strength for long service life.

• Anti-pollution model available for heavily contaminated regions to prevent flashover issues.

The GW9 disconnector adopts a single-phase structure, with each phase consisting of:

• Base frame

• Support insulator

• Blade (moving contact arm)

• Contact components

The blade side is equipped with adjustable screws and springs to regulate contact pressure. At the upper end, a fixed pull hook and self-locking device are installed, allowing safe manual operation. This structure ensures stable conductivity, reliable performance, and ease of maintenance.
