Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, often referred to as an isolation disconnect switch, is ingeniously crafted for application on high voltage power transmission and distribution lines, specifically at 10(12, 15, 24)kV. It seamlessly facilitates the opening and closing of single-phase or three-phase circuits while maintaining voltage presence but without bearing any load.

Meticulously engineered for single-phase operation in three-phase line systems, this switch stands out for its simplistic design, economic advantage, and user-friendly nature. With available rated currents of 200, 400, 600, 800, 1000, and 1250 amps, the switch is composed of a base, post insulators, conductive elements, and a mechanical section. The unique gate knife mechanism ensures smooth circuit operation, featuring two conductive blades per phase. These blades are complemented by external compression springs on either side, allowing precise adjustment of spring height to achieve optimal contact pressure. The switch is effortlessly operated through an insulated hook stick, equipped with a robust self-locking device.

Working Environment:

The altitude must not exceed 1000 meters;

Ambient temperature: maximum should not surpass +40°C; minimum should not fall below -30°C;

Outdoor wind speeds should remain within 35 meters/second;

Seismic intensity must remain within 8 degrees; the installation site should avoid frequent severe vibrations.

The installation environment must be free from harmful gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could compromise the switch's insulation and conductivity.

Note:

IN INSTANCES WHERE THE NORMAL USE CONDITIONS ARE SURPASSED, USERS MAY ENGAGE IN DIALOGUE WITH THE COMPANY FOR SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Carefully remove dust and dirt from all components, and meticulously clean the surface of the insulating porcelain bottle.
2. Thoroughly scrub the wiring surface of the ground screw.
3. Apply an even layer of industrial Vaseline to all rotating parts and contact areas.
4. Inspect the contact surfaces and adjust the height of the compression spring to ensure the contact pressure aligns with Table II specifications.
5. This switch is exclusively designed for hoisting use and operates in tandem with the transformer on the line.
6. The switch is available with a rated current capacity of 200-400 ampere hours, typically employing three mounting holes. For 600-1000A, three mounting holes are used.

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

Inspect all components for potential damage, with particular attention to the insulating porcelain bottle for any cracks or damage.

Ensure the contact surface of the conductive part remains in optimal condition.
