Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, often referred to as an isolation disconnect switch, is meticulously crafted for deployment on expansive 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is engineered to seamlessly open and close single-phase or three-phase circuits with voltage present but without a load.

This switch is engineered for single-phase operation in three-phase line systems, distinguished by its straightforward design, affordability, and user-friendly operation. It offers a range of rated currents including 200, 400, 600, 800, 1000, and 1250 amps. The switches are composed of a base, post insulators, conductive components, and a mechanical section, boasting a gate knife structure for circuit operation. Each phase's gate knife is equipped with two conductive blades and external compression springs on both sides, allowing adjustment of spring height to achieve optimal contact pressure. The switch is operated using an insulated hook stick for precise opening and closing actions and includes a reliable self-locking device.

Working Environment:

Ensures operation at altitudes up to 1000 meters;

Withstands ambient temperatures with a ceiling of +40°C and a floor of -30°C;

Capable of enduring outdoor wind speeds up to 35 meters/second;

Designed to handle seismic intensities up to 8 degrees, the installation site should remain free from frequent severe vibrations.

The installation site must be free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that could severely affect insulation and conductivity.

Note:

WHEN SPECIFIED NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO NEGOTIATE CUSTOM SOLUTIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove dust and dirt from parts, and meticulously clean the surface of the insulating porcelain bottle.
2. Ensure the cleanliness of the ground screw wiring surface by scrubbing it.
3. Apply a protective layer of industrial Vaseline to the rotating components and contact areas.
4. Inspect the contact surface and fine-tune the compression spring height to ensure contact pressure aligns with specifications in Table II.
5. This switch is intended exclusively for hoisting applications and should be used in conjunction with the transformer on the line.
6. The switch's rated current spans 200-400 ampere hours, typically involving three mounting holes. For 600-1000A, three mounting holes are also used.

Conduct an annual inspection of the following switch components:
Diligently remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's surface.

Inspect all parts for any damage, with special focus on checking the insulating porcelain bottle for any damage or cracks.

Verify that the contact surface of the conductive part maintains good condition.
