Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is ingeniously crafted for application on 10(12, 15, 24)kV high-voltage power transmission and distribution lines. It adeptly handles the opening and closing of single-phase or three-phase circuits while maintaining voltage presence, ensuring optimal performance without load interruption.

Expertly designed for single-phase integration within three-phase line systems, this switch stands out with its straightforward construction, affordability, and user-friendly operation. Cater to various operational needs with rated currents ranging from 200 to 1250 amps. Its sophisticated design includes a robust base, resilient post insulators, high-quality conductive components, and a reliable mechanical section. The innovative gate knife mechanism facilitates seamless circuit control, employing dual conductive blades reinforced by adjustable external compression springs to guarantee precise contact pressure. Operational efficiency is further enhanced by an insulated hook stick and a dependable self-locking device, ensuring secure and efficient opening and closing.

Working Environment:

Ideal for elevations not exceeding 1000 meters;

Operates efficiently in ambient temperatures, with a maximum of +40°C and a minimum of -30°C;

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

Built to endure seismic intensities up to 8 degrees, the installation site should remain free from frequent severe vibrations.

The installation area must be free from gases, chemical deposits, salt mist, dust, dirt, and other explosive or corrosive mediums that could critically impact the switch's insulation and conductivity.

Note:

WHEN NORMAL USE CONDITIONS EXCEED THE SPECIFICATIONS, NEGOTIATION WITH THE COMPANY IS ENCOURAGED FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Ensure all parts are meticulously cleaned of dust and dirt, paying particular attention to the insulating porcelain bottle's surface for optimal performance.
2. Thoroughly scrub the ground screw's wiring surface to ensure flawless conductivity.
3. Apply a protective layer of industrial Vaseline to all rotating components and contact areas to maintain smooth operation and longevity.
4. Inspect and adjust the contact surface and spring height to adhere to Table II's specified contact pressure, ensuring precision and reliability.
5. This switch is meticulously designed for hoisting use and is seamlessly compatible with transformers along the line, enhancing operational synergy.
6. With a rated current of 200-400 amperes, generally three mounting holes suffice, while the 600-1000A range may also require three mounting holes for optimal stability.

Conduct an annual inspection to ensure all switch components are in pristine condition:
Meticulously remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottle surface to maintain optimal functionality.

Inspect all components for potential damage, with a focused examination of the insulating porcelain bottle for cracks or signs of wear.

Verify the integrity of the conductive part's contact surface to ensure seamless operational performance.
