Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also revered as an isolation disconnect switch, is a pinnacle of engineering excellence. Crafted for 10(12, 15, 24)kV high voltage power transmission and distribution lines, this switch effortlessly opens and closes single-phase or three-phase circuits even when voltage is present, but load is absent. Its application in both single-phase and three-phase line systems highlights its versatility and efficiency.

This switch boasts a streamlined design, making it an epitome of simplicity, affordability, and user-friendliness. With available rated currents ranging from 200 to 1250 amps, it embodies flexibility. The switch consists of a robust base, durable post insulators, efficient conductive parts, and a precise mechanical section. A gate knife structure ensures seamless opening and closing of circuits, with each phase featuring dual conductive blades and external compression springs to guarantee optimal contact pressure. Operating the switch is effortlessly achieved using an insulated hook stick, complemented by a self-locking feature for added security.

Working Environment:

Altitude: Operation feasible up to 1000 meters above sea level.

Ambient Temperature: Thrives in climates up to +40°C and as low as -30°C.

Wind Resilience: Withstands outdoor wind speeds up to 35 meters/second.

Seismic Tolerance: Designed for regions with seismic intensity up to 8 degrees, excluding areas prone to severe vibrations.

Environmental Suitability: Ideal for sites devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive and corrosive mediums that could hinder insulation and conductivity.

Note:

FOR CONDITIONS EXCEEDING THE NORMAL PARAMETERS, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY FOR CUSTOM SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Ensure all components are free of dust and dirt; meticulously clean the insulating porcelain bottle's surface.
2. Thoroughly clean the grounding screw's wiring surface.
3. Apply a protective layer of industrial Vaseline on all rotating parts and contact areas to enhance durability.
4. Inspect the contact surface and adjust the compression spring's height to meet the specifications detailed in Table II.
5. Exclusively designed for hoisting applications, this switch partners seamlessly with line transformers.
6. For rated currents between 200-400 amperes, utilize three mounting holes. Similarly, 600-1000A applications also require three mounting holes for optimal stability.

Annual Maintenance Checklist:
Regularly clean all dirt from conductive parts, contact surfaces, and insulating porcelain bottles to maintain peak performance.

Inspect all components for damage, with particular focus on identifying any cracks or damage to the insulating porcelain bottle.

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