Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is expertly engineered for integration into 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is adept at maneuvering single-phase or three-phase circuits, seamlessly opening and closing them without load while voltage is present, ensuring superior performance and reliability.

This exceptional switch is tailored for single-phase utilization within three-phase line systems, boasting a straightforward design that is both economically advantageous and user-friendly. Offering a versatile range of rated currents—200, 400, 600, 800, 1000, and 1250 amps—these switches are constructed with an efficient assembly of a sturdy base, durable post insulators, conductive elements, and a precise mechanical section. The circuit's connectivity is managed through an innovative gate knife structure, comprising two conductive blades per phase, paired with external compression springs for optimal contact pressure. Operational efficiency is ensured through the use of an insulated hook stick for opening and closing, complemented by a self-locking device for added security.

Optimal Working Environment:

Positioned at altitudes not exceeding 1000 meters;

Designed for ambient temperatures: peaking at +40°C and dropping no lower than -30°C;

Withstands outdoor wind speeds of up to 35 meters per second;

Engineered to endure seismic intensity of up to 8 degrees, with installation sites ideally free from frequent severe vibrations.

Installation sites must be free from gases, chemical deposits, salt mist, dust, dirt, and other explosive or corrosive media that could severely compromise the switch's insulation and conductivity.

Important Note:

IF THE STANDARD OPERATING CONDITIONS ARE SURPASSED, USERS MAY NEGOTIATE WITH THE COMPANY FOR FURTHER ASSISTANCE.

Installation, Usage, and Adjustment Guidelines

Preparatory Installation Measures

1. Eliminate dust and debris meticulously from all components, ensuring the insulating porcelain bottle is thoroughly cleansed.
2. Meticulously clean the ground screw's wiring surface.
3. Coat all rotating components and contact areas with a protective layer of industrial Vaseline to ensure smooth operation.
4. Inspect the contact surface meticulously and adjust the compression spring's height to ensure compliance with Table II's contact pressure standards.
5. This switch is meticulously designed for hoisting operations and is intended to be used in conjunction with transformers along the line.
6. With a robust rated current capacity of 200-400 ampere hours, the switch typically utilizes three mounting holes, while models rated at 600-1000A also incorporate three mounting holes.

Annual Maintenance Checklist for Optimal Performance:
Thoroughly clean dirt from conductive components, contact surfaces, and insulating porcelain bottle surfaces to maintain pristine condition.

Conduct a comprehensive inspection for any damage, with particular attention to the insulating porcelain bottle for potential damage or cracks.

Ensure the contact surfaces of all conductive parts maintain optimal condition.
