Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch is a pinnacle of engineering excellence, renowned as an isolation disconnect switch, meticulously crafted for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This robust switch effortlessly facilitates the opening and closing of both single-phase and three-phase circuits under a voltage-present condition, while ensuring reliable performance without load transfer.

This innovative switch is purposefully designed for single-phase applications within three-phase line systems, boasting a straightforward structure, exceptional cost-efficiency, and unparalleled user-friendliness. It is available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps. The switch's sophisticated design comprises a sturdy base, durable post insulators, advanced conductive parts, and a precision mechanical section. Utilizing a state-of-the-art gate knife structure, this switch ensures seamless circuit operations. Each phase's gate knife integrates two conductive blades, complemented by external compression springs on either side, allowing for precise adjustments in spring height and optimal contact pressure. The switch’s operation is streamlined with an insulated hook stick, featuring an intuitive self-locking device for secure opening and closing.

Working Environment:

Ideal for locations with an altitude not exceeding 1000 meters;

Operates flawlessly within an ambient temperature range: maximum +40°C, minimum -30°C;

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

Capable of enduring seismic intensities up to 8 degrees; the installation site should be free from frequent severe vibrations.

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

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO ENGAGE IN NEGOTIATIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Meticulously remove any dust and dirt from all components, and ensure the insulating porcelain bottle surfaces are thoroughly cleaned.
2. Diligently scrub the wiring surface of the ground screw for optimal connectivity.
3. Apply a generous layer of industrial Vaseline to all rotating parts and contact areas for smooth operations.
4. Inspect the contact surface and make precise adjustments to the compression spring height to ensure the contact pressure aligns with Table II specifications.
5. This switch is exclusively designed for hoisting use and operates in perfect harmony with transformers on the line.
6. With a rated current of 200-400 ampere hours, this switch generally requires only three mounting holes. For currents of 600-1000A, three mounting holes remain consistently sufficient.

Ensure annual maintenance includes regular checks of the following switch components:
Efficiently remove dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain peak performance.

Conduct a thorough examination of all parts for potential damage, with particular attention to the insulating porcelain bottle for any signs of damage or cracks.

Verify the integrity of the contact surface on the conductive part to ensure flawless operation.
