Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, commonly recognized as an isolation disconnect switch, is meticulously engineered for seamless integration on 10(12, 15, 24)kV high voltage power transmission and distribution lines. Its primary function is to efficiently open and close single-phase or three-phase circuits while maintaining voltage presence, ensuring optimal performance without load transfer.

This switch is designed for single-phase operation in three-phase line systems, boasting a straightforward structure, economic advantages, and user-friendly features. The available rated currents encompass 200, 400, 600, 800, 1000, and 1250 amps. Each switch is composed of a robust base, post insulators, conductive components, and a mechanical section. The innovative gate knife structure facilitates smooth circuit opening and closing. Each phase's gate knife incorporates dual conductive blades, complemented by external compression springs for balanced pressure. The adjustable spring height guarantees precise contact pressure for the switch's gate knife. Operation is performed using an insulated hook stick for reliable opening and closing maneuvers, and includes a dependable self-locking device for security.

Working Environment:

The installation altitude should not exceed 1000 meters;

Ambient temperature requirements: a maximum of +40°C and a minimum of -30°C.

Outdoor wind conditions should not surpass a speed of 35 meters/second;

The seismic intensity at the installation site should not exceed 8 degrees; ensure the area is free from frequent intense vibrations.

The installation location must be free from gases, chemical deposits, salt mist, dust, and dirt, as well as any explosive or corrosive mediums that could severely impact the switch's insulation and conductivity.

Note:

SHOULD NORMAL USAGE CONDITIONS BE SURPASSED, USERS ARE ENCOURAGED TO DISCUSS ALTERNATIVES WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly clean dust and dirt from all components, and meticulously wipe the surface of the insulating porcelain bottle to ensure clarity.
2. Carefully scrub and prepare the wiring surface of the ground screw for optimal connectivity.
3. Apply a generous layer of industrial Vaseline to the rotating parts and contact areas for smooth operation.
4. Inspect the contact surface, and finely adjust the height of the compression springs to ensure that contact pressure aligns with the specifications outlined in Table II.
5. This switch is optimized for hoisting use and is specifically designed to function in conjunction with the transformer on the line.
6. The switch's rated current spans 200-400 ampere hours, typically utilizing three mounting holes. For 600-1000A usage, three mounting holes are similarly employed.

Annual inspection recommendations:
Diligently remove any dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's surface to maintain efficiency.

Vigilantly examine all components for damage, with special emphasis on checking the insulating porcelain bottle for any signs of damage or cracks.

Assess the condition of the conductive part's contact surface to ensure its integrity.
