Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a sophisticated yet economical solution also recognized as an isolation disconnect switch. Tailored for seamless performance on 10(12, 15, 24)kV high voltage power transmission and distribution lines, it excels in opening and closing single-phase or three-phase circuits effortlessly, maintaining voltage presence without load.

Designed explicitly for single-phase operations within three-phase line systems, this switch boasts a streamlined structure, exceptional cost-efficiency, and user-friendly functionality. Available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps, these switches are comprised of a robust base, reliable post insulators, high-quality conductive parts, and a well-engineered mechanical section. Featuring a gate knife mechanism for circuit operations, each phase's gate knife is equipped with two conductive blades and external compression springs on both sides. To ensure optimal contact pressure, simply adjust the spring height. Operating the switch is effortless with an insulated hook stick, and it includes a self-locking device for added security.

Working Environment:

Altitude: Restrictions apply up to 1000 meters;

Ambient temperature: Peaks at +40°C and falls to a minimum of -30°C;

Outdoor conditions: Designed to withstand wind speeds up to 35 meters/second;

Seismic durability: Withstands seismic intensity up to 8 degrees; the installation site should maintain stability, free from severe vibrations.

Ensure the installation site is free from gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive mediums that might compromise the switch's insulation and conductivity.

Note:

IN CASE OF OPERATING BEYOND THE SPECIFIED CONDITIONS, USERS ARE ADVISED TO DISCUSS OPTIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly cleanse all parts of dust and dirt, ensuring the insulating porcelain bottle's surface is meticulously wiped clean.
2. Scrub the ground screw's wiring surface to ensure optimal connectivity.
3. Apply industrial Vaseline to all rotating parts and contact areas for smooth operation.
4. Inspect contact surfaces and adjust the compression spring height to meet the standards outlined in Table II, ensuring adequate contact pressure.
5. This switch is primed only for hoisting applications and is intended to be used in conjunction with transformers along the line.
6. Rated for currents of 200-400 ampere hours, typically requiring only three mounting holes, while the 600-1000A version likewise utilizes three mounting holes.

Annually inspect the following switch components:
Clean all dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' surfaces.

Examine each part for any damage, paying special attention to the insulating porcelain bottle for signs of damage or cracks.

Ensure the contact surfaces of the conductive parts maintain pristine conditions.
