Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, widely recognized as an isolation disconnect switch, is expertly engineered for seamless operation on 10(12, 15, 24)kV high voltage power transmission and distribution networks. This switch is adept at opening and closing single-phase or three-phase circuits while maintaining voltage, yet without load, thus ensuring uninterrupted power flow.

Designed for single-phase applications in three-phase line systems, the switch is celebrated for its straightforward structure, cost-efficiency, and user-friendliness. It is available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps, providing flexibility for various requirements. The switch components consist of a sturdy base, robust post insulators, conductive parts, and a mechanical section. Its gate knife structure ensures reliable circuit operations, with each phase featuring two conductive blades enhanced by external compression springs for optimal contact pressure. The switch operation is simplified with an insulated hook stick for seamless opening and closing, complemented by a secure self-locking device.

Working Environment:

Suitable for altitudes up to 1000 meters;

Ambient temperature range: maximum not exceeding +40°C; minimum not dropping below -30°C;

Designed to withstand outdoor wind speeds of up to 35 meters/second;

Built to endure seismic intensity levels up to 8 degrees; the installation site should be free of frequent severe vibrations.

The installation site must be free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive elements that could severely compromise the switch's insulation and conductivity.

Note:

IF THE ABOVE STANDARD USE CONDITIONS ARE EXCEEDED, USERS MAY CONSULT THE COMPANY FOR SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove dust and dirt from all components, and delicately clean the surface of the insulating porcelain bottle for optimal performance.
2. Carefully scrub the wiring surface of the ground screw for secure connections.
3. Apply a fine layer of industrial Vaseline to the rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surface meticulously and adjust the compression spring height to meet the standards outlined in Table II for perfect contact pressure.
5. This switch is exclusively designed for hoisting applications in conjunction with transformers on the line, ensuring compatibility and efficiency.
6. The switch's rated current spans 200-400 ampere hours, typically utilizing three mounting holes for secure installation. For ratings between 600-1000A, three mounting holes are essential for stability.

Conduct annual checks on the following switch components to ensure optimal performance:
Thoroughly cleanse dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain high conductivity.

Inspect all components for potential damage, with particular attention to insulating porcelain bottles for any signs of damage or cracks.

Verify the quality of the contact surface on the conductive parts to ensure efficient electrical transmission.
