Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch—embracing superior craftsmanship as a quintessential isolation disconnect switch—tailored for the robust demands of 10(12, 15, 24)kV high voltage power transmission and distribution lines. It masterfully orchestrates the opening and closing of single-phase or three-phase circuits, maintaining a seamless operation with voltage present, yet without load.

Engineered for precision, the switch excels in single-phase applications within three-phase line systems. It stands out for its streamlined architecture, economic efficiency, and user-friendly nature. With rated currents available at 200, 400, 600, 800, 1000, and 1250 amps, these switches incorporate a robust configuration comprising a base, post insulators, conductive elements, and a mechanical section. The innovative gate knife structure ensures efficient circuit management: each phase deploying dual conductive blades empowered by external compression springs to guarantee optimal contact pressure. Operation is a breeze, facilitated by an insulated hook stick and a reliable self-locking mechanism.

Working Environment:

Ideal for altitudes not surpassing 1000 meters;

Capable of withstanding ambient temperatures, with a peak of +40°C and a low of -30°C;

Designed to operate efficiently with outdoor wind speeds up to 35 meters/second;

Capably withstanding seismic intensity up to 8 degrees, the installation site must be free from frequent, severe vibrations.

Avoid installing in environments laden with gases, chemical deposits, salt mist, dust, or dirt, as well as any explosive or corrosive substances that could critically impair the switch's insulation and conductivity.

Note:

WHEN ANY OF THESE STANDARD OPERATING CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO ENGAGE IN DISCUSSIONS WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Ensure all components are free from dust and dirt, meticulously cleansing the insulating porcelain bottle's exterior.
2. Meticulously scrub the wiring interface of the grounding screw to ensure perfect contact.
3. Apply a thin layer of industrial Vaseline to all rotating components and contact areas to ensure smooth operation.
4. Inspect the contact surface, adjusting the compression spring's height to achieve the necessary contact pressure as per Table II.
5. This switch is exclusively suited for hoisting applications in tandem with the line transformer, ensuring optimal functionality.
6. For rated currents of 200-400 ampere hours, three mounting holes are typically sufficient, with the same configuration serving for 600-1000A applications.

Perform a comprehensive annual check of the following switch components:
Diligently remove dirt from conductive elements, contact surfaces, and the insulating porcelain bottle's surface, ensuring pristine conditions.

Inspect every component for potential damage, particularly focusing on the insulating porcelain bottle for any signs of damage or cracks.

Verify the integrity of the contact surface of the conductive part to ensure reliability.
