Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, renowned as an isolation disconnect switch, is meticulously crafted for 10(12, 15, 24)kV high voltage power transmission and distribution lines. It facilitates the seamless opening and closing of single-phase or three-phase circuits, handling the voltage with precision while maintaining no load.

This switch is engineered for single-phase application within three-phase line systems, showcasing a straightforward design, economical operation, and user-friendly features. The available rated currents of 200, 400, 600, 800, 1000, and 1250 amps ensure versatile application. Each switch is composed of a sturdy base, reliable post insulators, conductive components, and a mechanical section. The gate knife structure is key for circuit management, with each phase's gate knife featuring dual conductive blades and external compression springs. These springs, when adjusted, ensure optimal contact pressure. Utilizing an insulated hook stick for operation, the switch is equipped with a self-locking device for security.

Working Environment:

Ensure operation at altitudes not exceeding 1000 meters;

Maintain ambient temperature with a maximum of +40°C and a minimum of -30°C;

The outdoor wind speed must remain below 35 meters/second;

Seismic intensity should not surpass 8 degrees; installation sites must remain free from frequent severe vibrations.

Installation sites should be devoid of gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive substances that could significantly compromise the switch's insulation and conductivity.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly clean parts, removing dust and dirt, and carefully wipe the surface of the insulating porcelain bottle for optimal performance.
2. Ensure the ground screw wiring surface is impeccably scrubbed.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surface and precisely adjust the compression spring's height to confirm that the contact pressure aligns with the standards set in Table II.
5. This switch is designed exclusively for hoisting applications and is intended to work in tandem with the transformer on the line.
6. Rated for 200-400 ampere hours, this switch typically utilizes three mounting holes, while the 600-1000A options also depend on three mounting holes for stability.

Perform an annual inspection of the following switch components:
Meticulously remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottle surfaces to maintain peak functionality.

Examine all components for potential damage, with particular attention to the integrity and absence of cracks in the insulating porcelain bottle.

Verify that the conductive part's contact surface is in optimal condition.
