Product Description

Product Description

Introducing the (H)GWBEB type, an outdoor high-voltage isolation switch, also called an isolation disconnect switch. Expertly crafted for 10(12, 15, 24)kV high voltage power transmission and distribution lines, it enables the seamless opening and closing of single-phase or three-phase circuits with voltage present, ensuring reliable performance without load.

Designed for single-phase use within three-phase line systems, this switch boasts a straightforward structure, making it cost-effective and user-friendly. Available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps, it comprises a base, post insulators, conductive parts, and a mechanical section. Its innovative gate knife structure facilitates smooth circuit operations. Each phase's gate knife features two conductive blades, enhanced by external compression springs, adjustable in height to ensure optimal contact pressure. Operated via an insulated hook stick, the switch includes a self-locking mechanism for secure open and close actions.

Working Environment:

Suitable for altitudes not exceeding 1000 meters;

Ambient temperature conditions: maximum of +40°C and a minimum of -30°C;

Withstands outdoor wind speeds up to 35 meters/second;

Engineered to endure seismic intensities up to 8 degrees; ideal installation sites are those free from frequent severe vibrations.

Installation areas must be free from gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive substances that could adversely impact the switch's insulation and conductivity.

Note:

FOR CONDITIONS EXCEEDING STANDARD USE, PLEASE DISCUSS WITH THE COMPANY FOR SPECIAL ARRANGEMENTS.

Installation, Use, and Adjustment

Pre-installation work

1. Ensure all parts are free from dust and dirt by thoroughly cleaning, and carefully wipe the surface of the insulating porcelain bottle.
2. Clean the wiring surface of the ground screw meticulously.
3. Safeguard all rotating parts and contact areas with a protective layer of industrial Vaseline.
4. Inspect the contact surface and adjust the compression spring height to make sure contact pressure aligns with Table II requirements.
5. This switch is exclusively designed for hoisting applications, working in harmony with transformers on the line.
6. The switch caters to a rated current range of 200-400 ampere hours, typically using three mounting holes. For 600-1000A, three mounting holes are also utilized.

Annual Maintenance Checklist:
Keep conductive parts, contact surfaces, and insulating porcelain bottle surfaces clear of dirt.

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

Regularly verify the integrity of the contact surface of the conductive part for optimal performance.
