Product Description

Product Description

Introducing our (H)GWBEB type outdoor high-voltage isolation switch, an essential tool for power professionals! This ingeniously crafted isolation disconnect switch is specifically engineered for 10(12, 15, 24)kV high voltage power transmission and distribution lines. It serves to seamlessly open and close single-phase or three-phase circuits with ease, even when voltage is present—though under no load conditions.

Our switch is optimally designed for single-phase use within three-phase line systems. It stands out for its straightforward architecture, affordability, and user-friendly nature. Offered in an impressive range of rated currents—200, 400, 600, 800, 1000, and 1250 amps—these switches are comprised of a robust base, durable post insulators, high-conductivity components, and a well-engineered mechanical section. The sophisticated gate knife structure ensures reliable circuit operations. Each phase's gate knife is equipped with two conductive blades and fortified with external compression springs on both sides. By adjusting the spring height, you can achieve the precise contact pressure needed for optimal performance. Operation is facilitated by an insulated hook stick, and a self-locking device adds further convenience and safety.

Working Environment:

Ideal for altitudes not exceeding 1000 meters;

Designed to withstand ambient temperatures with a maximum of +40°C and a minimum of -30°C;

Capable of enduring outdoor wind speeds up to 35 meters/second;

Built to resist seismic intensities up to 8 degrees, ensuring stability even in less-than-ideal locations without frequent severe vibrations.

Best suited for environments devoid of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive substances that could severely impact the switch's insulation and conductivity.

Note:

SHOULD THE ABOVE STANDARD CONDITIONS BE EXCEEDED, USERS ARE WELCOME TO ENGAGE IN NEGOTIATIONS WITH OUR COMPANY FOR CUSTOMIZED SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Ensure all components are free of dust and dirt, and meticulously clean the surface of the insulating porcelain bottle to uphold pristine standards.
2. Diligently scrub the wiring surface of the ground screw for optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation and longevity.
4. Inspect the contact surfaces and adjust the height of the compression spring to ensure the contact pressure meets the specifications outlined in Table II.
5. This switch is exclusively designed for hoisting applications and is intended to be used in tandem with a transformer on the line.
6. The switch is rated for currents between 200 to 400 amps per hour, typically using three mounting holes. For 600-1000A applications, three mounting holes are standard.

Conduct an annual check of the following components of the switch:
Thoroughly clean all conductive parts, contact surfaces, and the insulating porcelain bottle's surface to maintain optimal performance.

Inspect every component for potential damage. Pay special attention to the insulating porcelain bottle for any signs of damage or cracks.

Confirm the integrity of the contact surfaces on all conductive parts.
