Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also famously recognized as an isolation disconnect switch, is engineered with precision for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It excels in safely opening and closing single-phase or three-phase circuits without carrying the load, yet maintaining voltage presence.

This switch is meticulously crafted for single-phase applications within three-phase line systems, distinguished by its streamlined structure, affordability, and operational simplicity. Offered in an array of rated currents-200, 400, 600, 800, 1000, and 1250 amps-these switches are composed of a robust base, sturdy post insulators, conductive elements, and a mechanical section. Featuring a gate knife structure for circuit manipulation, each phase's gate knife is equipped with dual conductive blades, complemented by external compression springs on both sides. The necessary contact pressure is achieved by adjusting the spring height. An insulated hook stick facilitates operation, with a built-in self-locking mechanism ensuring secure action.

Working Environment:

Altitude not exceeding 1000 meters;

Ambient temperature: maximum not above +40°C; minimum not below -30°C;

Outdoor wind speed not exceeding 35 meters/second;

Seismic intensity not exceeding 8 degrees; the installation site should remain free from frequent severe vibrations.

The installation site should be devoid of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could significantly compromise the switch's insulation and conductivity.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN NEGOTIATE WITH THE COMPANY.

 

Installation, Use and Adjustment

Pre-installation work

1. Meticulously remove dust and dirt from all parts, ensuring the insulating porcelain bottle's surface is carefully wiped clean.
2. Thoroughly scrub the wiring surface of the ground screw.
3. Generously apply a layer of industrial Vaseline to the rotating parts and contact areas for optimal performance.
4. Inspect the contact surface and adjust the compression spring's height to ensure the contact pressure aligns with the specifications in Table II.
5. This switch is exclusively designed for hoisting use, intended for seamless integration with the transformer on the line.
6. The switch's rated current ranges from 200-400 ampere hours, typically employing three mounting holes, while the 600-1000A range also utilizes three mounting holes.

Perform an annual check-up on the following switch components:
Thoroughly clear dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' surface.

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

Ensure the contact surface of the conductive part is in impeccable condition.
