Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is ingeniously designed for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. Its primary function is to seamlessly open and close single-phase or three-phase circuits under voltage, even in demanding environmental conditions.

This switch, tailored for single-phase applications in three-phase line systems, stands out with its minimalist design, affordability, and user-friendly operation. It comes with a choice of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. The switch is composed of a robust base, durable post insulators, conductive components, and a mechanical section. It employs an innovative gate knife structure for circuit interruption, with each phase featuring dual conductive blades and external compression springs to ensure optimal contact pressure. The switch is manipulated using an insulated hook stick, complemented by a reliable self-locking mechanism.

Working Environment: Ideal Conditions for Optimal Performance

The Altitude should not exceed 1000 meters to maintain optimal efficiency.

Ambient temperature parameters: Maximum of +40°C; Minimum of -30°C, supporting a wide range of climatic zones.

Outdoor wind speed must not exceed 35 meters/second, ensuring stability and reliability in gusty conditions.

Seismic intensity threshold: not exceeding 8 degrees. The installation site should remain free from frequent severe vibrations, safeguarding the integrity of the switch.

Installation sites should be devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive substances that could compromise the switch's insulation and conductivity.

Note: Essential Considerations

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN NEGOTIATE WITH THE COMPANY to explore bespoke solutions or adjustments.

Installation, Use, and Adjustment: Ensuring Seamless Operation

Pre-installation work: Essential Preparations

1. Begin by meticulously removing dust and dirt from the components, ensuring the insulating porcelain bottle's surface is pristine.
2. Thoroughly scrub the wiring surface of the ground screw to ensure flawless connectivity.
3. Apply a generous layer of industrial Vaseline to the rotating parts and contact areas to facilitate smooth operations.
4. Check the contact surface and adjust the compression spring height to ensure the contact pressure aligns with Table II specifications.
5. This switch is exclusively designed for hoisting use, intended to work seamlessly with the transformer on the line.
6. The switch's rated current is 200-400 ampere hours, typically requiring three mounting holes, while 600-1000A configurations also utilize three mounting holes for secure installation.

Perform annual checks on the following switch components to maintain peak performance:
Regularly remove any dirt accumulation from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain efficiency.

Inspect all components for potential damage. Special attention should be given to the insulating porcelain bottle for any signs of damage or cracks.

Ensure the conductive part's contact surface is intact and functioning optimally.
