Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, renowned as an isolation disconnect switch, stands as an exceptional solution for managing 10(12, 15, 24)kV high voltage power transmission and distribution lines. It skillfully enables the opening and closing of single-phase or three-phase circuits, maintaining the voltage presence without loading. This innovative design ensures reliability and efficiency, tailored to meet the complex requirements of modern electrical infrastructures.

Crafted for optimal performance in single-phase applications within three-phase line systems, this switch is celebrated for its straightforward design, economical advantage, and unparalleled ease of use. Choose from a versatile range of rated currents: 200, 400, 600, 800, 1000, to 1250 amps. Composed of a robust base, sturdy post insulators, precise conductive parts, and a resilient mechanical section, the switch features an ingenious gate knife structure for seamless circuit operation. Each phase's gate knife is uniquely designed with dual conductive blades, enhanced with external compression springs on either side, ensuring precise contact pressure through adjustable spring height. Operate the switch effortlessly using an insulated hook stick, complemented by a reliable self-locking mechanism for assured safety.

Working Environment:

Designed for altitudes not exceeding 1000 meters;

Thrives in ambient temperatures, ranging from a maximum of +40°C to a minimum of -30°C;

Engineered to withstand outdoor wind speeds of up to 35 meters per second;

Boasts resilience against seismic activities, withstanding intensities not exceeding 8 degrees. Installation sites should remain free from frequent severe vibrations.

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

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Ensure all components are free from dust and dirt by meticulously wiping the insulating porcelain bottle's surface.
2. Thoroughly clean the wiring surface of the ground screw to ensure optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation.
4. Examine the contact surface and precisely adjust the compression spring height to adhere to Table II's specified contact pressure.
5. This switch is exclusively designed for hoisting applications and is intended for use in conjunction with a line transformer.
6. For a rated current of 200-400 ampere hours, generally three mounting holes are utilized, while 600-1000A applications also employ three mounting holes for secure installation.

Annually inspect the following switch components to maintain optimal performance:
Diligently remove any dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's surface to ensure cleanliness.

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

Ensure the conductive part's contact surface remains in excellent condition for optimal operational efficacy.
