Product Description

Product Description

Introducing the (H)GWBEB outdoor high-voltage isolation switch – the pinnacle of reliability for 10(12, 15, 24)kV power transmission. This essential tool, known as an isolation disconnect switch, masterfully manages the flow of power by opening and closing circuits with voltage present but no load. Perfect for both single-phase and three-phase systems, it stands as a guardian of power distribution.

This switch is meticulously crafted for single-phase applications within three-phase line systems, offering unparalleled simplicity, cost-efficiency, and effortless operation. With rated currents available in 200, 400, 600, 800, 1000, and 1250 amps, the switch is a robust assembly of a base, post insulators, conductive components, and a precision-engineered mechanical section. The gate knife design ensures seamless circuit engagement, with each gate knife featuring dual conductive blades and external compression springs. Adjusting spring height secures optimal contact pressure. Operated with an insulated hook stick, the switch also boasts a self-locking mechanism, enhancing safety and reliability.

Working Environment:

Perfectly suited for altitudes up to 1000 meters;

Operates efficiently in ambient temperatures ranging from a brisk -30°C to a warm +40°C;

Durable against outdoor winds up to 35 meters/second;

Engineered to withstand seismic intensities up to 8 degrees, ensuring stability even in tremor-prone areas with minimal vibrations.

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

Note:

WHEN EXTREME CONDITIONS ARISE BEYOND THESE SPECIFICATIONS, USERS ARE ENCOURAGED TO DISCUSS CUSTOM SOLUTIONS DIRECTLY WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Meticulously remove dust and debris from all components, ensuring the insulating porcelain bottle is clean and pristine.
2. Thoroughly scrub the ground screw's wiring surface for optimal conductivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas, ensuring smooth operation.
4. Inspect the contact surfaces meticulously and adjust the compression spring height to meet the specified contact pressure in Table II.
5. Designed exclusively for hoisting applications, this switch pairs seamlessly with transformers along the line.
6. For rated currents of 200-400 amps, typically three mounting holes are sufficient. For 600-1000 amps, the same three holes are utilized.

Annual Maintenance Checklist:
Thoroughly clean dirt from all conductive parts, contact surfaces, and insulating porcelain bottles ensuring optimal performance.

Inspect all components for damage; pay particular attention to the insulating porcelain bottle for any signs of damage or cracks.

Ensure the conductive part's contact surface remains in excellent condition.
