Product Description

Product Description

Introducing the cutting-edge (H)GWBEB type outdoor high-voltage isolation switch, a paramount tool in modern electrical infrastructure. Familiarly known as an isolation disconnect switch, this marvel is tailor-made for seamless operation on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is engineered to efficiently open and close single-phase or three-phase circuits, gracefully handling the presence of voltage without load. Its design optimizes operational safety and reliability, ensuring the utmost in performance excellence.

This exceptional switch is perfectly crafted for single-phase utilization within three-phase line systems. It stands out for its simplicity, economic efficiency, and user-friendly operation, making it a top choice for diverse applications. Offering an impressive range of rated currents at 200, 400, 600, 800, 1000, and 1250 amps, these switches are built with precision. Each unit encompasses a robust base, post insulators, conductive components, and a sophisticated mechanical assembly. The ingenious gate knife design allows for seamless circuit operations, with each phase's gate knife featuring dual conductive blades and external compression springs for optimal pressure adjustment. An insulated hook stick facilitates effortless opening and closing operations, complemented by a reliable self-locking mechanism to ensure safety and stability.

Working Environment:

Efficiently designed for altitudes not exceeding 1000 meters;

Engineered to withstand ambient temperature extremes: a maximum of +40°C and a minimum of -30°C;

Built to endure outdoor wind speeds up to 35 meters/second;

A masterpiece of engineering, designed for seismic intensities not exceeding 8 degrees, ensuring stability even in regions prone to vibrations.

The integrity of the installation site is crucial; the environment must be free of gases, chemical deposits, salt mist, dust, dirt, and other hazardous or corrosive elements that could compromise the switch's insulation and conductivity.

Note:

SHOULD YOUR REQUIREMENTS EXCEED THE NORMAL USE CONDITIONS OUTLINED ABOVE, A DISCUSSION WITH BEIERBIAN GROUP CO., LTD IS ENCOURAGED TO EXPLORE CUSTOMIZED SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly cleanse all parts to remove dust and dirt, and delicately wipe the surface of the insulating porcelain bottle to ensure pristine condition.
2. Meticulously scrub the wiring surface of the ground screw to ensure optimal conductivity.
3. Coat the rotating parts and contact areas with a protective layer of industrial Vaseline to enhance durability and performance.
4. Ensure the contact pressure aligns with Table II by checking the contact surface and adjusting the compression spring height accordingly.
5. Exclusively designed for hoisting applications, this switch operates in harmony with the transformer on the line, ensuring seamless integration and functionality.
6. With a rated current capacity of 200-400 ampere hours, this switch typically requires only three mounting holes. For higher currents of 600-1000A, three mounting holes are still utilized, optimizing installation efficiency.

Annual maintenance protocol - regularly inspect the following components of the switch:
Diligently remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottle to maintain peak performance.

Conduct a thorough examination of all parts for potential damage, with particular attention to inspecting the insulating porcelain bottle for any signs of cracks or deterioration.

Vigilantly check the condition of the conductive part's contact surface to ensure flawless connectivity and operation.
