Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also referred to as an isolation disconnect switch, is meticulously engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is adept at managing the opening and closing of single-phase or three-phase circuits under voltage without load, ensuring seamless operation in demanding environments.

Crafted for single-phase application within three-phase systems, this switch stands out due to its simplistic architecture, affordability, and remarkable user-friendliness. It offers a range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps, tailored for diverse needs. Each switch comprises a robust base, reliable post insulators, efficient conductive parts, and a well-engineered mechanical section. The gate knife structure facilitates efficient circuit management, with each phase's knife featuring two conductive blades and compression springs on either side. The height of these springs can be adjusted to secure optimal contact pressure. For operational efficiency, an insulated hook stick enables easy opening and closing, complemented by a reliable self-locking mechanism.

Working Environment:

Altitude: Not exceeding 1000 meters, ensuring reliable performance at elevated locations.

Ambient Temperature: Maximum +40°C; Minimum -30°C, capable of withstanding extreme temperature variations.

Wind Speed: Designed to operate effectively in outdoor conditions with wind speeds up to 35 meters/second.

Seismic Intensity: Suitable for areas with seismic activity not exceeding 8 degrees; the installation site must be relatively stable with minimal vibrations.

Environmental Conditions: The switch is robust against gases, chemical deposits, salt mist, dust, dirt, and other potentially explosive or corrosive elements that could impair its insulation and conductivity.

Note:

WHEN NORMAL USE CONDITIONS ARE SURPASSED, USERS SHOULD ENGAGE IN DISCUSSIONS WITH THE COMPANY FOR A CUSTOM SOLUTION.

 

Installation, Use and Adjustment

Pre-installation Work

1. Meticulously remove dust and impurities from all parts, ensuring the insulating porcelain bottle surfaces are immaculately cleaned.
2. Thoroughly scrub and clean the wiring surface of the ground screw to ensure a seamless connection.
3. Apply a protective layer of industrial Vaseline strategically on rotating parts and contact areas to enhance durability and function.
4. Inspect the contact surface rigorously, adjusting the compression spring height to comply with the standards outlined in Table II.
5. This switch is exclusively designed for hoisting applications and is optimized for use alongside transformers on the line.
6. Rated at 200-400 ampere hours, it typically requires three mounting holes. For 600-1000A applications, it similarly utilizes three mounting holes for secure installation.

Annual Maintenance Checklist:
Regularly clean conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain optimal performance.

Conduct thorough inspections for any damage, with heightened attention to the insulating porcelain bottle to detect potential damage or cracks.

Assess the contact surface of the conductive part to ensure excellent connectivity and operation.
