Product Description

Product Description

Our (H)GWBEB type outdoor high-voltage isolation switch, also referred to as an isolation disconnect switch, is expertly engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is adept at opening and closing single-phase or three-phase circuits with voltage present but without load, offering unmatched reliability.

Designed for single-phase functionality within three-phase line systems, this switch stands out due to its simplistic structure, superior cost-effectiveness, and user-friendly operation. It supports a versatile range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. The switch's construction features a sturdy base, resilient post insulators, conductive elements, and an efficient mechanical section. Utilizing a gate knife structure for seamless circuit management, each phase's gate knife includes two conductive blades complemented by external compression springs on both sides. The adjustable spring height ensures optimal contact pressure. An insulated hook stick facilitates easy manual operation for both opening and closing, while a self-locking device enhances operational safety.

Working Environment:

Ideal for elevations up to 1000 meters;

Can withstand ambient temperatures ranging from a chilly -30°C to a warm +40°C;

Performs efficiently in outdoor wind conditions not exceeding 35 meters/second;

Designed to endure seismic activities up to 8 degrees, the installation venue should be free from frequent intense vibrations.

The installation site must be devoid of gases, chemical residues, salt mist, dust, dirt, and other explosive or corrosive elements that could significantly impair the switch's insulation and conductivity.

Note:

SHOULD THE ABOVE STANDARD OPERATING CONDITIONS BE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS OPTIONS WITH THE COMPANY FOR CUSTOMIZED SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Ensure all parts are free from dust and dirt; meticulously clean the insulating porcelain bottle's surface.
2. Thoroughly scrub the ground screw's wiring surface.
3. Apply a protective layer of industrial Vaseline on all rotating parts and contact areas.
4. Inspect the contact surface and adjust the compression spring's height to meet the requirements specified in Table II.
5. This switch is exclusively designed for hoisting applications and to work synergistically with transformers on the line.
6. Primarily, this switch's rated current spans 200-400 amperes, requiring three mounting holes, while ranges of 600-1000A also utilize three mounting holes.

Conduct an annual inspection of the following switch components:
Cleanse all conductive parts, contact surfaces, and the insulating porcelain bottles' surfaces of any accumulated dirt.

Assess all parts for potential damage, with particular attention to the insulating porcelain bottle for any signs of damage and cracking.

Verify the integrity of the conductive part's contact surface.
