Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, an essential component in modern power systems. Commonly referred to as an isolation disconnect switch, this device is expertly engineered for seamless operation on 10(12, 15, 24)kV high voltage transmission and distribution lines, making it ideal for opening and closing circuits—single-phase or three-phase—without load but with voltage present. Its robust design ensures reliability and safety in critical applications.

Designed for single-phase operations within three-phase systems, this switch stands out for its straightforward structure, cost-efficiency, and user-friendly interface. With available rated currents of 200, 400, 600, 800, 1000, and 1250 amps, it is adaptable to various needs. Its components include a sturdy base, durable post insulators, high-quality conductive elements, and a reliable mechanical section. The innovative gate knife mechanism enables efficient circuit control, featuring dual conductive blades and external compression springs for optimal contact pressure, easily adjustable by spring height. Operate this switch smoothly with an insulated hook stick, and rely on its secure self-locking device for safe usage.

Working Environment:

Designed for altitudes not exceeding 1000 meters;

Functions efficiently within a temperature range: maximum of +40°C and a minimum of -30°C;

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

Seismic intensity tolerance up to 8 degrees; the installation site should be free from frequent severe vibrations to ensure stability.

Installation sites must remain free of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive environments that could compromise the switch's insulation and conductivity.

Note:

WHEN STANDARD USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS SPECIFIC REQUIREMENTS WITH THE COMPANY. CUSTOM SOLUTIONS MAY BE AVAILABLE.

Installation, Use, and Adjustment

Pre-installation work

1. Thoroughly clean parts from dust and dirt, and carefully polish the insulating porcelain bottle surface to maintain optimal performance.
2. Ensure the wiring surface of the ground screw is impeccably scrubbed for secure connections.
3. Apply a protective layer of industrial Vaseline on rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surface and adjust the compression spring height to achieve the perfect contact pressure as per Table II specifications.
5. This switch is engineered exclusively for hoisting applications and is designed to work in harmony with the transformer on the line.
6. The switch, with a rated current of 200-400 ampere hours, typically requires only three mounting holes, while 600-1000A use three mounting holes for secure installation.

Annual Maintenance Checklist: Regularly inspect these vital components to ensure long-lasting functionality.
Meticulously clean dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain conductive integrity.

Inspect all components for potential damage, with particular attention to the insulating porcelain bottle for any signs of damage or cracks.

Verify that the contact surface of the conductive part remains in excellent condition for consistent performance.
