Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, affectionately known as an isolation disconnect switch, is meticulously crafted for seamless integration with 10(12, 15, 24)kV high voltage power transmission and distribution lines. This robust switch is adept at effortlessly opening and closing single-phase or three-phase circuits while under voltage, ensuring ultimate convenience and safety for operators.

Designed specifically for single-phase applications within three-phase line systems, this switch boasts a straightforward structure, exceptional cost-effectiveness, and unparalleled ease of use. The switch caters to various rated currents including 200, 400, 600, 800, 1000, and 1250 amps, offering remarkable versatility. Its composition includes a solid base, durable post insulators, efficient conductive parts, and a reliable mechanical section. A sophisticated gate knife design is employed for circuit operations, with each phase's gate knife featuring dual conductive blades and external compression springs on either side. Adjusting the spring's height ensures optimal contact pressure for the gate knife. The switch is adeptly operated with an insulated hook stick, facilitating smooth opening and closing, complemented by a dependable self-locking device.

Working Environment:

Altitude requirements: not exceeding 1000 meters;

Ambient temperature conditions: maximum of +40°C; minimum of -30°C;

Outdoor wind speed: not exceeding 35 meters/second;

Seismic intensity compatibility: not exceeding 8 degrees; the installation site must remain free from frequent severe vibrations.

Installation site restrictions: must be devoid of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could significantly impact the switch's insulation and conductivity.

Note:

WHEN NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO ENGAGE IN NEGOTIATIONS WITH THE COMPANY.

 

Installation, Use and Adjustment

Pre-installation work

1. Ensure all parts are free from dust and dirt, meticulously wiping the insulating porcelain bottle's surface.
2. Thoroughly scrub the wiring surface of the ground screw to maintain optimal connectivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas for enhanced longevity.
4. Inspect contact surfaces and adjust the compression spring's height to meet the specifications outlined in Table II, guaranteeing adequate contact pressure.
5. This switch is designed exclusively for hoisting applications and is intended for use alongside the transformer on the line.
6. The rated current for this switch ranges from 200-400 amperes, typically requiring only three mounting holes, whereas 600-1000A applications also utilize three mounting holes.

Regular annual maintenance checklist for optimal switch performance:
Clear any dirt from conductive parts, contact surfaces, and the insulating porcelain bottles to maintain efficiency.

Thoroughly inspect all components for damage, focusing on identifying damage or cracks in the insulating porcelain bottle.

Verify the integrity of the contact surface within the conductive part to ensure proper functionality.
