Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, commonly referred to as an isolation disconnect switch, is expertly engineered for utilization on high voltage power transmission and distribution lines ranging from 10(12, 15, 24)kV. It is ideal for safely opening and closing single-phase or three-phase circuits, even when voltage is present, but without load.

Crafted for single-phase use within three-phase line systems, this switch is distinguished by its straightforward design, affordability, and user-friendly operation. Available in various rated currents-200, 400, 600, 800, 1000, and 1250 amps-the switches incorporate a base, post insulators, conductive components, and a mechanical section. The gate knife structure ensures smooth circuit operations, with each phase's gate knife comprising dual conductive blades and external compression springs on both sides. By adjusting the spring height, optimal contact pressure is achieved. Operated with an insulated hook stick and featuring a self-locking mechanism, this switch is both efficient and reliable.

Working Environment:

Designed for altitudes not exceeding 1000 meters;

Capable of withstanding ambient temperatures, with a maximum of +40°C and a minimum of -30°C;

Engineered to endure outdoor wind speeds of up to 35 meters/second;

Built to operate under seismic conditions not exceeding 8 degrees, ensuring stability at sites free from frequent severe vibrations.

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

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

 

Installation, Use and Adjustment

Pre-installation work

1. Ensure all parts are free of dust and dirt, and meticulously clean the surface of the insulating porcelain bottle.
2. Thoroughly scrub the wiring surface of the ground screw to ensure optimal conductivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas for smooth operation.
4. Examine the contact surface and adjust the compression spring height to ensure contact pressure is in line with Table II specifications.
5. This switch is tailored for hoisting applications and is intended for use alongside transformers on main lines.
6. The switch is rated for currents from 200 to 400 ampere hours, typically using three mounting holes. For 600-1000A applications, three mounting holes are standard.

Annually, it's crucial to inspect the following switch components:
Clear dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's exterior.

Inspect all components for wear, with a focus on identifying any damage or cracks in the insulating porcelain bottle.

Verify the integrity of the conductive part's contact surfaces.
