Product Description

Product Description

Introducing the innovative (H)GWBEB type outdoor high-voltage isolation switch, renowned as the isolation disconnect switch! Meticulously crafted for seamless integration into 10(12, 15, 24)kV high voltage power transmission and distribution networks, this switch excels at executing flawless operations on single-phase or three-phase circuits without load. It stands ready to perform with voltage present, offering unparalleled reliability and safety!

Designed for single-phase deployment within three-phase line systems, this switch stands out due to its intelligent engineering: a simple structure complemented by cost-effectiveness and user-friendly operation. Enjoy a range of rated currents from 200 to 1250 amps, catering to diverse needs with precision. Crafted with a robust base, post insulators, conductive parts, and a mechanical section, the switch employs a sophisticated gate knife mechanism, featuring dual conductive blades per phase, equipped with adjustable external compression springs on both sides. This ensures optimal contact pressure for smooth operations. Operate effortlessly using an insulated hook stick for both opening and closing, with a reliable self-locking device for added security.

Working Environment:

Engineered for altitudes not exceeding 1000 meters;

Efficiently functions within an ambient temperature range: max +40°C; min -30°C;

Thrives in outdoor settings with wind speeds up to 35 meters/second;

Built to withstand seismic intensity up to 8 degrees, ideal for stable installation sites without frequent severe vibrations.

Optimal performance is ensured in environments free from gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive substances that could compromise insulation and conductivity.

Note:

WHEN OPERATIONAL CONDITIONS EXCEED STANDARD SPECIFICATIONS, USERS ARE ENCOURAGED TO CONSULT WITH OUR COMPANY FOR CUSTOMIZED SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Begin by meticulously removing dust and dirt from all components, ensuring the insulating porcelain bottle surfaces are pristine.
2. Thoroughly clean the ground screw wiring surfaces to ensure optimal connectivity.
3. Apply industrial Vaseline generously to rotating parts and contact areas to ensure smooth operation and longevity.
4. Inspect contact surfaces rigorously, adjusting the compression spring height to meet the specifications outlined in Table II for optimal contact pressure.
5. This switch is perfectly engineered for hoisting applications and is primarily used in tandem with transformers along the line.
6. With a rated current ranging from 200 to 400 amperes, the switch typically utilizes three mounting holes; for currents between 600 and 1000 amperes, three mounting holes are standard.

Perform a comprehensive annual check to ensure reliability and safety:
Meticulously clean conductive parts, contact surfaces, and the surfaces of insulating porcelain bottles to maintain optimal performance.

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

Ensure the contact surfaces of the conductive parts maintain excellent condition for seamless operations.
