Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, commonly referred to as an isolation disconnect switch, stands as a pinnacle of design for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This state-of-the-art switch allows the seamless opening and closing of single-phase or three-phase circuits without any load while voltage is present, ensuring optimal performance in demanding environments.

Expertly crafted for single-phase functionality in three-phase line systems, this switch is celebrated for its straightforward design, cost efficiency, and user-friendly operation. Offering rated currents ranging from 200, 400, 600, 800, 1000, to 1250 amps, these switches are composed of a robust base, post insulators, conductive components, and an intuitive mechanical section. The gate knife structure is ingeniously designed for precise circuit opening and closing. Each phase’s gate knife, equipped with dual conductive blades and external compression springs, offers adjustable spring height to ensure the perfect contact pressure. The switch's operation is effortlessly conducted using an insulated hook stick, complemented by a reliable self-locking mechanism.

Working Environment:

Altitude limitations not exceeding 1000 meters;

Ambient temperature: peaking at a maximum of +40°C and withstanding a minimum of -30°C;

Outdoor wind speed must remain below 35 meters/second;

Seismic resilience not surpassing 8 degrees; the installation site should remain free from frequent severe vibrations.

The installation site must remain devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive elements that could severely compromise the switch's insulation and conductivity.

Note:

WHEN THE STANDARD USE CONDITIONS ARE EXCEEDED, A CONSTRUCTIVE DIALOGUE WITH THE COMPANY IS WELCOMED TO DISCUSS POSSIBLE SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Meticulously remove dust and dirt from the components, ensuring the insulating porcelain bottle surface is pristinely wiped.
2. Thoroughly scrub the wiring surface of the ground screw for optimal conductivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to enhance durability.
4. Inspect the contact surface and fine-tune the height of the compression spring to ensure that the contact pressure aligns with the standards set forth in Table II.
5. This switch is exclusively designed for hoisting applications and efficiently collaborates with transformers on the line for enhanced performance.
6. The switch, with a rated current of 200-400 ampere hours, typically utilizes three mounting holes, while the 600-1000A models are also accommodated with three mounting holes.

Annually, a thorough check of the following switch components is essential:
Diligently clear dirt from conductive parts, contact surfaces, and the insulating porcelain bottles to maintain peak efficiency.

Conduct a rigorous inspection of all parts for any damage, with particular focus on detecting damage or cracks in the insulating porcelain bottle.

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