Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, stands as a pinnacle of engineering for use on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This switch is expertly crafted to open and close single-phase or three-phase circuits without load while maintaining voltage presence, ensuring reliability and safety in your power networks.

Engineered with simplicity and functionality in mind, this switch is ideal for single-phase operations within three-phase line systems. It boasts a straightforward structure, making it both economical and user-friendly. With available rated currents ranging from 200 to a robust 1250 amps, these switches include a base, post insulators, conductive parts, and a mechanical section. The innovative gate knife structure facilitates seamless opening and closing of circuits. Each gate knife phase is equipped with two conductive blades, complemented by external compression springs on both sides. Fine-tuning the spring height ensures optimal contact pressure for the switch's gate knife, while an insulated hook stick enables effortless operation. The inclusion of a self-locking device enhances operational security.

Working Environment:

Ideal for altitudes not exceeding 1000 meters;

Designed to withstand ambient temperatures with a maximum of +40°C and a minimum as low as -30°C;

Capable of enduring outdoor wind speeds up to 35 meters/second;

Seismic intensity up to 8 degrees is permissible, provided the installation site is free from frequent severe vibrations.

Installation sites should be devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that can seriously impact the switch's insulation and conductivity.

Note:

FOR CONDITIONS BEYOND THE STATED USAGE PARAMETERS, USERS ARE ENCOURAGED TO NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Meticulously remove dust and dirt from all parts, ensuring the insulating porcelain bottle surfaces are spotless.
2. Carefully scrub the wiring surface of the ground screw for optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to guarantee smooth operation.
4. Inspect the contact surface diligently, adjusting the compression spring height to meet the specified contact pressure as outlined in Table II.
5. This switch is specifically designed for hoisting applications and is intended for use alongside transformers on the line.
6. The switch accommodates a rated current of 200-400 ampere hours, utilizing typically three mounting holes, with 600-1000A versions also using three mounting holes for installation.

Annual maintenance checklist for the switch:
Thoroughly remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottle exterior to maintain optimal performance.

Conduct a comprehensive inspection for damage across all parts, placing special emphasis on checking the insulating porcelain bottle for any damage or cracks.

Ensure the contact surfaces of conductive parts maintain excellent condition for reliable operation.
