Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is expertly crafted for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is built to seamlessly open and close single-phase or three-phase circuits without load but with voltage present, ensuring reliable performance and safety.

Designed specifically for single-phase applications within three-phase line systems, this switch stands out with its straightforward structure, impeccable cost-effectiveness, and user-friendly operation. Available rated currents range from 200 to 1250 amps, catering to diverse energy needs. The switch is constructed with a base, post insulators, conductive components, and a mechanical section. A gate knife structure is pivotal for achieving circuit operation. Each phase comprises two conductive blades, enhanced with external compression springs on both sides. Adjusting the spring height fine-tunes the contact pressure, optimizing the switch's gate knife performance. The switch is operated with an insulated hook stick for precise opening and closing, and is equipped with a robust self-locking mechanism.

Working Environment:

Altitude should not exceed 1000 meters to ensure optimal switch operation.

Ambient temperature must range between +40°C maximum and -30°C minimum, accommodating diverse climatic conditions.

Outdoor wind speed should remain below 35 meters/second for stable operation.

Seismic intensity must not surpass 8 degrees; the installation site should be free from frequent severe vibrations.

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

Note:

WHEN NORMAL USE CONDITIONS EXCEED THE SPECIFICATIONS, USERS MAY NEGOTIATE CONDITIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove dust and dirt from all components, carefully cleaning the surface of the insulating porcelain bottle to ensure pristine condition.
2. Gently scrub the wiring surface of the ground screw to maintain optimal conductivity.
3. Apply a protective layer of industrial Vaseline on the rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surface and adjust the height of the compression spring, ensuring the contact pressure aligns with Table II for optimal performance.
5. This switch is designed exclusively for hoisting use and is intended to work in conjunction with transformers on the line, ensuring efficient energy management.
6. The switch is available with a rated current ranging from 200 to 400 ampere hours, utilizing three mounting holes typically. For 600-1000 ampere applications, three mounting holes are also used.

Regular annual maintenance is essential to ensure peak performance. Check the following components of the switch:
Remove accumulated dirt from the conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain optimal conductivity.

Conduct a thorough inspection of all components for any damage, with a focus on detecting any damage or cracks in the insulating porcelain bottle.

Ensure the contact surface of the conductive parts is in excellent condition, maintaining efficient electricity flow.
