Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, an engineering marvel in the realm of power transmission and distribution. Designed specifically for high voltage lines ranging from 10 to 24kV, this isolation disconnect switch is an essential tool for controlling single-phase or three-phase circuits under voltage without load. Its robust design ensures seamless operation and reliable performance.

Crafted with precision, this switch is optimized for single-phase application within three-phase systems, showcasing a blend of simplicity and economic efficiency. Available in rated currents from 200 up to 1250 amps, its construction comprises a sturdy base, durable post insulators, efficient conductive parts, and a mechanical section. The ingenious gate knife structure facilitates smooth circuit operations, supported by external compression springs for optimal contact pressure. With an insulated hook stick, users can effortlessly operate the switch, which also boasts a self-locking mechanism for added safety and reliability.

Working Environment:

Designed to excel at altitudes not exceeding 1000 meters;

Capable of withstanding ambient temperatures from a scorching +40°C to a chilly -30°C;

Resilient against outdoor wind speeds up to 35 meters/second, ensuring stability in windy conditions;

Built to withstand seismic intensities up to 8 degrees, ideally suited for sites without frequent severe vibrations.

The installation environment must be free from harmful gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive substances that could compromise the switch's insulation and conductivity.

Note:

WHEN CONDITIONS EXCEED NORMAL PARAMETERS, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly cleanse all parts, especially the surfaces of insulating porcelain bottles, ensuring they are free from dust and dirt.
2. Meticulously scrub the wiring surface of the ground screw to ensure pristine connectivity.
3. Apply a premium layer of industrial Vaseline to all rotating parts and contact areas for smooth operation and longevity.
4. Inspect the contact surfaces and fine-tune the compression spring height to meet the specifications outlined in Table II, ensuring optimal contact pressure.
5. This switch is specifically designed for hoisting applications and is perfectly compatible with transformers on the line.
6. For currents of 200-400 ampere hours, typically, three mounting holes are utilized. Similarly, for 600-1000A applications, three mounting holes are employed to ensure secure installation.

Annual maintenance checklist for optimal performance:
Regularly remove any accumulated dirt from conductive parts, contact surfaces, and the surfaces of insulating porcelain bottles.

Conduct thorough inspections for any damage, with particular attention to the integrity of the insulating porcelain bottle, checking for any cracks or damage.

Ensure that the contact surfaces of all conductive parts maintain optimal condition and connectivity.
