Product Description

Product Description

The (H)GWBEB series outdoor high-voltage isolation switch, also referred to as an isolation disconnect switch, represents the pinnacle of precision engineering. Crafted specifically for the rigorous demands of 10(12, 15, 24)kV high voltage power transmission and distribution lines, this switch excels in its ability to open and close either single-phase or three-phase circuits, doing so efficiently without load but with voltage present. This makes it an indispensable asset in your power management toolkit.

This innovative switch is perfectly suited for single-phase applications within three-phase line systems, boasting a remarkable trifecta of simplicity, cost-effectiveness, and user-friendliness. Available in a range of rated currents - 200, 400, 600, 800, 1000, and 1250 amps - these switches are meticulously designed with a base, post insulators, conductive elements, and a robust mechanical section. The sophisticated gate knife mechanism ensures seamless opening and closing of circuits, with each phase's gate knife featuring dual conductive blades and robust external compression springs. By adjusting the spring height, optimal contact pressure is effortlessly achieved for the switch's gate knife. The operation is enhanced with an insulated hook stick, providing precise control over opening and closing actions, complemented by a built-in self-locking device.

Working Environment:

Altitude: Operable at altitudes not exceeding 1000 meters; ensuring adaptability across a range of terrains.

Ambient Temperature: Designed to perform in a wide temperature spectrum, from a bracing -30°C to a maximum of +40°C, ensuring reliability in diverse climates.

Wind Speed: Engineered to withstand outdoor wind conditions with speeds up to 35 meters per second, guaranteeing steadfast performance amidst nature's challenges.

Seismic Resilience: Built to endure seismic activities up to 8 degrees of intensity, provided the installation site is not prone to frequent severe vibrations, assuring stability and safety.

Environmental Considerations: The installation site must be free from damaging gases, chemical deposits, salt mist, dust, dirt, and any other explosive or corrosive substances that could compromise the switch's insulation and conductivity.

Note:

Should the specified normal use conditions be exceeded, we invite you to engage in discussions with our company to explore tailored solutions that meet your specific requirements.

Installation, Use and Adjustment

Pre-installation Work

1. Commence by meticulously removing any dust and dirt from the switch components, ensuring the insulating porcelain bottle is wiped to a pristine finish.
2. Thoroughly scrub the wiring surface of the ground screw to ensure optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas, ensuring smooth operation and longevity.
4. Inspect the contact surfaces diligently and adjust the height of the compression spring to conform with the standards outlined in Table II, ensuring precise contact pressure.
5. This switch is expertly designed for hoisting applications and is seamlessly integrated with transformers along the line, offering unparalleled utility.
6. Rated for 200-400 ampere hours, this switch typically utilizes three mounting holes, with 600-1000A configurations also employing three mounting holes for secure installation.

Annual Maintenance: Conduct comprehensive annual inspections of the following components to ensure optimal functionality:
Diligently remove any dirt from the conductive parts, contact surfaces, and the surface of insulating porcelain bottles to maintain peak performance.

Thoroughly inspect all parts for potential damage, focusing on the integrity of the insulating porcelain bottle to identify any damages or cracks.

Assess the condition of the conductive part's contact surfaces to ensure they are functioning optimally.
