Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is meticulously crafted for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It facilitates seamless opening and closing of single-phase or three-phase circuits without altering the load, while maintaining voltage presence, ensuring reliability and safety in power management.

This innovative switch is tailored for single-phase application within three-phase line systems, renowned for its streamlined structure, cost-effectiveness, and user-friendly design. It is available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps. The switch is composed of a robust base, sturdy post insulators, efficient conductive parts, and a durable mechanical section. Featuring a sophisticated gate knife structure for circuit operations, each phase's gate knife comprises two conductive blades, with strategically placed external compression springs enhancing contact pressure. Height adjustments of these springs ensure optimal contact pressure. The switch is adeptly operated with an insulated hook stick for both opening and closing functions, and includes a reliable self-locking device for added security.

Working Environment:

Altitude should not exceed 1000 meters;

Ambient temperature: maximum should not surpass +40°C; minimum should not drop below -30°C;

Outdoor wind speed should remain below 35 meters/second;

Seismic intensity should not exceed 8 degrees; the installation location must be free from frequent severe vibrations.

The installation site must be devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive elements that could severely impact the switch's insulation and conductivity.

Note:

IF THE ABOVE NORMAL USAGE CONDITIONS ARE EXCEEDED, CUSTOMERS ARE ENCOURAGED TO DISCUSS ALTERNATIVE ARRANGEMENTS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove dust and dirt from all components, ensuring the surface of the insulating porcelain bottle is meticulously wiped clean.
2. Clean the wiring surface of the ground screw with precision.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surface and adjust the compression spring height to ensure the contact pressure is in alignment with Table II specifications.
5. This switch is specifically designed for hoisting applications and is intended to be used in tandem with the transformer on the line.
6. The switch's rated current ranges from 200-400 ampere hours, typically utilizing three mounting holes, while 600-1000A configurations also use three mounting holes for secure installation.

Conduct an annual inspection of the following switch components:
Eliminate dirt from conductive parts, contact surfaces, and the insulating porcelain bottle surface to maintain optimal performance.

Examine all parts for any damage, with particular focus on inspecting the insulating porcelain bottle for any signs of damage or cracks.

Ensure the contact surface of the conductive parts is in excellent condition.
