Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also celebrated as an isolation disconnect switch, is meticulously engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This device excels at seamlessly opening and closing single-phase or three-phase circuits without a load yet with voltage present, ensuring operational reliability and safety.

This switch is specially crafted for single-phase utilization within three-phase line systems, boasting a straightforward architecture, impressive cost-efficiency, and user-friendly operation. It offers an array of rated current options: 200, 400, 600, 800, 1000, and 1250 amps. The robust design includes a sturdy base, resilient post insulators, conductive components, and a mechanical assembly. Employing a gate knife structure for circuit operations, each gate knife phase is equipped with dual conductive blades secured by external compression springs on both sides. By adjusting the spring height, optimal contact pressure is ensured for the switch's gate knife. The insulated hook stick facilitates seamless operation, while a self-locking mechanism enhances safety.

Working Environment:

For optimal performance, installation should be at altitudes not exceeding 1000 meters.

The ambient temperature must remain within a maximum of +40°C and a minimum of -30°C, ensuring robust functionality.

Outdoor wind speeds should not surpass 35 meters/second to maintain operational stability.

Seismic intensity should not exceed 8 degrees, and the installation site must remain free from frequent severe vibrations to guarantee durability.

The installation site should be devoid of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could significantly compromise the switch's insulation and conductivity.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN NEGOTIATE WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Ensure all parts are meticulously dusted and cleaned, especially the insulating porcelain bottle's surface.
2. Thoroughly scrub the wiring surface of the ground screw for optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surface carefully and adjust the compression spring height to ensure contact pressure aligns with Table II specifications.
5. This switch is optimized solely for hoisting applications and is designed for integration with the transformer on the line.
6. The rated current for this switch ranges from 200-400 ampere hours, typically utilizing three mounting holes. Models supporting 600-1000A also employ three mounting holes for secure installation.

Annual maintenance checklist for optimal performance includes:
Regularly remove any accumulation of dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's exterior.

Inspect all components for potential damage, placing special emphasis on ensuring the insulating porcelain bottle is free from any cracks.

Verify that the contact surface of the conductive parts maintains optimal condition.
