Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, also known as the isolation disconnect switch, is meticulously engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This advanced switch enables the seamless opening and closing of single-phase or three-phase circuits without load, all while voltage remains present, ensuring optimal functionality and safety.

Crafted for single-phase applications within three-phase line systems, this switch stands out with its streamlined structure, cost-efficiency, and unparalleled ease of operation. The available rated current options include an impressive range of 200, 400, 600, 800, 1000, and 1250 amps. These sophisticated switches are comprised of essential components such as a robust base, durable post insulators, high-grade conductive parts, and an efficient mechanical section. The ingenious gate knife structure facilitates the precise opening and closing of circuits. Each phase is equipped with a gate knife featuring dual conductive blades, complemented by external compression springs on both sides. By adjusting the spring height, the required contact pressure is effortlessly achieved for the switch's gate knife. Operational excellence is ensured with the use of an insulated hook stick for opening and closing actions, and the added security of a self-locking device.

Working Environment:

Altitude not exceeding 1000 meters;

Ambient temperature: maximum not above +40°C; minimum not below -30°C;

Outdoor wind speed not exceeding 35 meters/second;

Seismic intensity not exceeding 8 degrees; the installation site should not experience frequent severe vibrations.

The installation site should remain free of gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive elements that could significantly impair the switch's insulation and conductivity.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS CAN NEGOTIATE WITH THE COMPANY FOR CUSTOMIZED SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Diligently remove dust and dirt from all components, ensuring the insulating porcelain bottle surfaces are wiped meticulously clean.
2. Thoroughly scrub the wiring surface of the ground screw to ensure optimal connectivity.
3. Apply a fine layer of industrial Vaseline to all rotational parts and contact areas for enhanced protection and smooth operation.
4. Inspect the contact surfaces and adjust the height of the compression spring to ensure the contact pressure aligns precisely with Table II standards.
5. Exclusively designed for hoisting use, this switch is perfectly suited to work in conjunction with transformers along the line, enhancing overall efficiency.
6. Rated currents of 200-400 ampere hours generally utilize three mounting holes; for 600-1000A, three mounting holes are essential for secure installation.

Conduct an annual inspection of the following switch components to maintain peak performance:
Meticulously remove any dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to maintain impeccable condition.

Examine all parts for potential damage, with particular attention to the insulating porcelain bottle, checking for any damage or cracks.

Ensure the contact surface of the conductive part is in excellent condition for optimal functionality.
