Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, often referred to as an isolation disconnect switch, is masterfully crafted for seamless operation on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This switch excels in opening and closing single-phase or three-phase circuits, all while maintaining voltage presence. Offering unmatched reliability and efficiency, it stands as a pivotal component in high voltage systems.

The switch is purpose-built for single-phase applications within three-phase line systems, renowned for its uncomplicated design, cost-effectiveness, and user-friendly operation. It boasts a range of rated currents, including 200, 400, 600, 800, 1000, and 1250 amps, catering to diverse needs. Each intricately designed switch is composed of a robust base, durable post insulators, conductive elements, and a precision-engineered mechanical section. The innovative gate knife mechanism ensures precise circuit operations, with each phase's knife comprising dual conductive blades, enhanced by external compression springs on either side. Adjusting the spring height fine-tunes the essential contact pressure for flawless switch performance. Operational simplicity is achieved through an insulated hook stick, complemented by a reliable self-locking device for secure actions.

Working Environment:

Altitude threshold: not exceeding 1000 meters;

Ambient temperature: peak not above +40°C; base not below -30°C;

Outdoor wind speed: capped at 35 meters/second;

Seismic intensity limit: not exceeding 8 degrees; installation sites should be free from frequent severe vibrations.

Installation sites must be devoid of gases, chemical residues, salt mist, dust, dirt, or other explosive or corrosive elements that could significantly impact the switch's insulation and conductivity.

Note:

WHEN THE NORMAL CONDITIONS OF USE ARE EXCEEDED, USERS HAVE THE OPTION TO DISCUSS ALTERNATIVE ARRANGEMENTS WITH OUR COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove dust and dirt from all components, ensuring that the insulating porcelain bottle’s surface is meticulously cleaned.
2. Carefully scrub the wiring surface associated with the ground screw to ensure optimal connectivity.
3. Apply a protective layer of industrial Vaseline to rotating parts and contact areas to enhance longevity and performance.
4. Inspect the contact surfaces, adjusting the compression spring height to guarantee that the contact pressure aligns with the specifications outlined in Table II.
5. This switch is exclusively designed for hoisting use and is meant to operate in tandem with transformers on the line, ensuring reliability and functionality.
6. The switch’s rated current capacity ranges from 200 to 400 ampere hours. For optimal setup, generally three mounting holes are utilized, while 600-1000A configurations also employ three mounting holes.

Conduct an annual inspection on the following switch components:
Diligently clean dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' surfaces for sustained performance.

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

Examine the contact surfaces of conductive parts to ensure they are in optimal condition for effective operation.
