Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, renowned as an isolation disconnect switch, is meticulously engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. Its primary function is to facilitate the opening and closing of single-phase or three-phase circuits while maintaining voltage presence but devoid of load. This essential component guarantees the reliability and safety of your power systems.

Exclusively designed for single-phase use within three-phase line systems, this switch boasts a straightforward yet robust structure, making it incredibly economical and user-friendly. It supports an impressive range of rated currents, including 200, 400, 600, 800, 1000, and 1250 amps, catering to diverse installation needs. The innovative design comprises a sturdy base, post insulators, conductive elements, and a mechanical section, featuring a sophisticated gate knife structure to efficiently manage circuit operations. Each phase is equipped with two conductive blades, fortified with external compression springs on both sides. The height adjustable springs ensure optimal contact pressure, vital for seamless operation. The switch is ingeniously operated via an insulated hook stick, paired with a self-locking device for enhanced safety and reliability.

Working Environment:

Setting an altitude benchmark, it is suitable for locations not exceeding 1000 meters, ensuring broad applicability.

Engineered to perform in ambient temperatures ranging from a sweltering +40°C to a chilling -30°C, catering to diverse climatic conditions.

Endure wind speeds up to 35 meters/second, making it robust against various weather challenges.

Built to withstand seismic intensities up to 8 degrees, designed for areas with minimal severe vibrations.

The installation site must remain free from gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive substances that could compromise the switch's insulation and conductivity.

Note:

SHOULD THE ABOVE CONDITIONS BE EXCEEDED, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY FOR SOLUTIONS.

 

Installation, Use, and Adjustment

Pre-installation work

1. Ensure a pristine setup by meticulously removing all dust and debris from components, and gently wiping the insulating porcelain bottle's surface for optimal performance.
2. Thoroughly scrub the ground screw's wiring surface to ensure uninterrupted conductivity.
3. Apply industrial Vaseline to all rotating parts and contact areas, providing smooth operation.
4. Verify the contact surface and fine-tune the compression spring's height to ensure the contact pressure aligns with Table II specifications.
5. Uniquely suitable for hoisting use, it is designed to complement transformers in line-based applications.
6. Boasting a rated current of 200-400 ampere hours, the design generally employs three mounting holes, while the 600-1000A variant also uses three mounting holes.

Perform annual maintenance checks on the following switch components:
Maintain electrical efficiency by clearing dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's surface.

Inspect all parts for any damage, with particular vigilance on the insulating porcelain bottle to detect potential cracks or damages.

Ensure the contact surface of the conductive part is impeccable to maintain optimal performance.
