Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, an essential component in the realm of electrical transmission. Known by its alternative name, the isolation disconnect switch, it's expertly crafted for seamless integration on 10(12, 15, 24)kV high voltage power lines. This device is your go-to solution to safely open and close single-phase or three-phase circuits, managing the task efficiently without any load, yet with the electrical current in place.

Designed for single-phase operations within three-phase line systems, this switch stands out with its streamlined design, budget-friendly cost, and user-friendly operation. Choose from a variety of rated currents such as 200, 400, 600, 800, 1000, and 1250 amps. Each switch is a cohesive unit composed of a robust base, durable post insulators, precision conductive parts, and a reliable mechanical section. The circuit is seamlessly opened and closed using an innovative gate knife structure, with each phase's knife featuring dual conductive blades enhanced by external compression springs. By adjusting the spring height, optimal contact pressure is achieved, ensuring superior performance. The switch's operation is a breeze with an insulated hook stick and comes with a secure self-locking device for added safety.

Working Environment:

The switch is designed for altitudes not exceeding 1000 meters, ensuring reliable performance even in elevated terrains.

Designed to operate in a range of temperatures, the switch can handle a maximum ambient temperature of +40°C and a minimum of -30°C, adapting to various climates.

Capable of withstanding outdoor wind speeds up to 35 meters per second, this switch is built to endure the elements.

Engineered for areas with a seismic intensity of up to 8 degrees, the switch's installation site should remain free from frequent severe vibrations to maintain its integrity.

The ideal installation location should be devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive agents that could compromise the switch's insulation and conductivity.

Note:

SHOULD THE NORMAL USAGE CONDITIONS BE EXCEEDED, USERS ARE ENCOURAGED TO ENGAGE IN NEGOTIATIONS WITH THE COMPANY FOR ALTERNATIVE ARRANGEMENTS.

 

Installation, Use and Adjustment

Pre-installation work

1. Ensure that all components are free from dust and dirt. Carefully clean the surface of the insulating porcelain bottle to guarantee optimal performance.
2. Meticulously scrub the wiring surface of the ground screw, preparing it for efficient installation.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation and longevity.
4. Inspect the contact surface thoroughly. Adjust the compression spring height to meet the standards outlined in Table II, ensuring appropriate contact pressure.
5. This switch is specifically designed for hoisting applications and is intended to be used in conjunction with transformers on the line, optimizing electrical distribution.
6. The switch, with a rated current range of 200-400 ampere hours, typically uses three mounting holes for installation. The 600-1000A variety also utilizes three mounting holes, accommodating higher currents.

Conduct annual inspections to maintain the switch's reliability and performance:
Consistently remove dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to keep them in pristine condition.

Check every component for potential damage, with particular attention given to inspecting the insulating porcelain bottle for any cracks or damage.

Examine the contact surface of the conductive part to ensure it remains in top condition for optimal performance.
