Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is engineered to perform flawlessly on 10(12, 15, 24)kV high voltage power transmission and distribution lines. Its primary function is to seamlessly open and close single-phase or three-phase circuits without load while maintaining voltage presence, ensuring maximum reliability and safety.

Crafted for single-phase operations within three-phase line systems, this switch boasts a simplistic yet highly efficient design, offering unparalleled cost-effectiveness and user-friendliness. It is available in a variety of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. The switch comprises a robust base, durable post insulators, high-conductivity parts, and a mechanically sound section. Its innovative gate knife structure enables smooth circuit operations. Each phase's gate knife is equipped with two conductive blades and external compression springs on both sides, allowing for precise spring height adjustments to achieve optimal contact pressure. Operation is executed with an insulated hook stick, and the switch is equipped with a secure self-locking mechanism.

Working Environment:

The altitude should not exceed 1000 meters;

Ensures functionality in a temperature range: maximum not above +40°C; minimum not below -30°C;

Designed for outdoor use, withstanding wind speeds up to 35 meters/second;

Built to endure seismic intensities not exceeding 8 degrees. It should be installed in locations free from frequent severe vibrations.

Ideal installation sites should be devoid of gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive substances that might adversely affect the switch's insulation and conductivity.

Note:

SHOULD YOUR CONDITIONS EXCEED THE STANDARD PARAMETERS, CUSTOM SOLUTIONS CAN BE DISCUSSED WITH THE COMPANY.

Installation, Use, and Adjustment

Pre-installation work

1. Begin by meticulously removing dust and dirt from all parts, ensuring the surface of the insulating porcelain bottle is carefully wiped to uphold its integrity.
2. Thoroughly scrub the wiring surface of the ground screw for optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation.
4. Inspect and adjust the contact surface, modifying the compression spring height to meet the specifications detailed in Table II to ensure dependable contact pressure.
5. This switch is exclusively designed for hoisting applications and works seamlessly in conjunction with a transformer on the line.
6. With a rated current of 200-400 ampere hours, three mounting holes are generally sufficient. For higher currents, 600-1000A, three mounting holes are still recommended.

Conduct annual inspections to ensure reliability: check these critical parts of the switch regularly:
Diligently remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottle surface to maintain peak conductivity.

Thoroughly inspect all components, with particular attention to the insulating porcelain bottle for any signs of damage or cracks.

Verify that the contact surface of the conductive parts remains in excellent condition for uninterrupted performance.
