Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is a state-of-the-art device crafted for excellence on 10(12, 15, 24)kV high voltage power transmission and distribution lines. Specifically engineered to deftly open and close single-phase or three-phase circuits without load but with voltage present, this switch exemplifies reliability and precision.

The switch is meticulously designed for single-phase use within three-phase line systems, offering a harmonious blend of simplicity, cost-effectiveness, and user-friendliness. Available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps, it boasts a robust construction featuring a base, post insulators, conductive parts, and a mechanical section. The innovative gate knife structure ensures seamless opening and closing of circuits, with each phase's gate knife comprised of two conductive blades, augmented by external compression springs on both sides. By adjusting the spring height, optimal contact pressure for the switch's gate knife is achieved. Operated with ease using an insulated hook stick, the switch also incorporates a self-locking device for enhanced safety and efficiency.

Working Environment:

Designed for altitudes not exceeding 1000 meters;

Capable of withstanding ambient temperatures with a maximum not above +40°C and a minimum not below -30°C;

Designed to endure outdoor wind speeds not exceeding 35 meters per second;

Manufactured to withstand a seismic intensity not exceeding 8 degrees, ensuring stability in locations not prone to frequent severe vibrations.

The installation environment should be free from gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive substances that could significantly impair the switch’s insulation and conductivity.

Note:

SHOULD THE CONDITIONS FOR NORMAL USE EXCEED THOSE SPECIFIED, WE ENCOURAGE USERS TO NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Ensure that all parts are free from dust and dirt, and meticulously clean the surface of the insulating porcelain bottle to maintain optimal performance.
2. Thoroughly clean the wiring surface of the ground screw to ensure secure connections.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to enhance longevity and performance.
4. Inspect the contact surface and adjust the height of the compression spring to ensure the contact pressure aligns with Table II recommendations.
5. This switch is specifically designed for hoisting applications, functioning seamlessly in tandem with transformers on the line.
6. With a rated current of 200-400 amperes, this switch generally utilizes three mounting holes. For 600-1000A applications, three mounting holes are applied.

Conduct a thorough annual inspection of the following switch components to ensure optimal functionality:
Meticulously remove any dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles.

Check all components for any signs of damage, with particular attention to ensure the insulating porcelain bottle is free from damage and cracks.

Verify the integrity of the conductive part's contact surface to maintain efficient operation.
