Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a marvel of engineering also known as an isolation disconnect switch. Perfectly crafted for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines, this switch is adept at opening and closing single-phase or three-phase circuits under voltage, ensuring superior performance without load interruption.

Designed for single-phase application within three-phase line systems, this switch shines with its straightforward structure, affordability, and unmatched user-friendliness. Choose from rated currents of 200, 400, 600, 800, 1000, and 1250 amps. Each switch is a composite of a robust base, durable post insulators, efficient conductive parts, and a reliable mechanical section. Employing a gate knife structure for seamless circuit operations, each phase features a dual conductive blade system, enhanced by external compression springs on either side. By adjusting these springs, users can fine-tune the contact pressure for optimal operation. Experience ease-of-use with an insulated hook stick for precise opening and closing, complemented by a secure self-locking device for heightened safety.

Working Environment:

Altitude: Capable of performing at heights not exceeding 1000 meters;

Temperature Range: Unwavering performance between +40°C to -30°C, ensuring adaptability in various climates;

Wind Resistance: Withstands outdoor wind speeds up to 35 meters/second;

Seismic Resilience: Engineered to endure seismic intensities up to 8 degrees, making it suitable for areas without frequent severe vibrations.

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

Note:

WHEN OPERATING BEYOND NORMAL CONDITIONS, USERS ARE ENCOURAGED TO CONSULT WITH OUR COMPANY TO EXPLORE CUSTOMIZED SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Ensure all components are free of dust and dirt by cleaning thoroughly, and gently polish the insulating porcelain bottle's surface to perfection.
2. Meticulously clean the wiring surface of the ground screw to ensure optimal connectivity.
3. Enhance the longevity of rotating parts and contact areas by applying a protective layer of industrial Vaseline.
4. Inspect the contact surface and adjust the compression spring height to meet the contact pressure specifications outlined in Table II.
5. This switch is exclusively designed for hoisting applications and is intended for seamless synergy with line transformers.
6. With a rated current range of 200-400 ampere hours, the switch is typically mounted using three holes. For currents between 600-1000A, three mounting holes are standard.

Annual Inspection Checklist: Ensure longevity and optimal performance by regularly checking the following components:
Thoroughly remove any accumulations of dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces.

Inspect every component for damage, focusing especially on identifying any cracks or damage in the insulating porcelain bottle.

Verify the integrity of the conductive part contact surfaces to ensure optimal performance.
