Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch is a pinnacle of engineering excellence, distinctly crafted to serve on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This masterful device opens and closes single-phase or three-phase circuits seamlessly, all while maintaining voltage presence, ensuring uninterrupted reliability.

Specifically tailored for single-phase operations within three-phase line systems, this switch epitomizes simplicity, affordability, and user-friendliness. With a range of available rated currents including 200, 400, 600, 800, 1000, and 1250 amps, it stands as a versatile solution. Constructed with a base, post insulators, conductive elements, and a sophisticated mechanical section, it employs a gate knife mechanism for flawless circuit operations. Each phase's gate knife is engineered with dual conductive blades, augmented by external compression springs on either side. By adjusting the spring height, it ensures optimal contact pressure. The switch's insulated hook stick allows precise operation, complemented by a secure self-locking feature for added safety.

Working Environment:

Altitude restrictions up to a majestic 1000 meters;

Withstand ambient temperatures ranging from a chilling -30°C to a scorching +40°C;

Designed to brave outdoor wind speeds up to a brisk 35 meters per second;

Constructed to endure seismic intensities reaching up to 8 degrees, and optimally installed in sites free from frequent intense vibrations.

This switch thrives best in environments free from harmful gases, corrosive chemical deposits, salt mist, dust, and dirt. Ensure installation sites are devoid of explosive or corrosive mediums that could impair insulation and conductivity.

Installation, Use and Adjustment

Pre-installation Steps

1. Thoroughly cleanse parts of dust and debris, ensuring the insulating porcelain bottle's surface is meticulously wiped clean.
2. Carefully cleanse the ground screw's wiring surface to ensure optimal connection.
3. Apply a protective coating of industrial Vaseline to rotating components and contact areas to enhance durability and performance.
4. Inspect the contact surface meticulously and adjust the compression spring height to ensure the contact pressure aligns with standards in Table II.
5. Designed exclusively for hoisting applications, this switch functions harmoniously in tandem with transformers on the line.
6. Tailored for rated currents between 200-400 ampere hours, typically employing three mounting holes, with robust support for 600-1000A installations using three mounting configurations.

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

Examine all components for any signs of damage, with particular focus on detecting cracks or damage to the insulating porcelain bottle.

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