Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, widely recognized as an isolation disconnect switch, is expertly crafted for seamless use on high voltage power transmission and distribution lines, specifically at 10(12, 15, 24)kV. It skillfully manages the opening and closing of single-phase or three-phase circuits, offering unmatched efficiency without carrying load, while maintaining a voltage presence.

This switch, meticulously designed for single-phase usage within three-phase line systems, is celebrated for its efficient simplicity, cost-effectiveness, and user-friendly operation. Available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps, the switches comprise a robust base, dependable post insulators, conductive parts, and a mechanical section. The innovative gate knife structure ensures flawless circuit control, utilizing two conductive blades per phase, complemented by external compression springs on both sides. Precision in contact pressure is achievable by adjusting the spring height. Operation is hassle-free with an insulated hook stick, and enhanced by a reliable self-locking device.

Working Environment:

Optimized for altitudes not exceeding 1000 meters;

Ambient temperature range: with a maximum not exceeding +40°C and a minimum not below -30°C;

Designed for outdoor installation with wind speeds not surpassing 35 meters/second;

Seismic resilience not exceeding 8 degrees; installation sites should remain free from frequent and severe vibrations.

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

Note:

WHEN NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS CUSTOM SOLUTIONS WITH THE COMPANY.

 

Installation, Use and Adjustment

Pre-installation work

1. Ensure all parts are free from dust and dirt, and gently wipe the insulating porcelain bottle surfaces to maintain pristine condition.
2. Thoroughly clean the wiring surfaces of the ground screw for optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surfaces and adjust the compression spring height to meet the specified contact pressure in Table II, ensuring optimal performance.
5. Designed exclusively for hoisting applications, this switch is perfectly paired with transformers along the line for efficient operation.
6. For optimal installation, this switch supports a rated current of 200-400 ampere hours with typically three mounting holes, while 600-1000A also employs three mounting holes, ensuring stability and adaptability.

Ensure yearly maintenance checks on the following switch components:
Meticulously clean dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain efficiency.

Thoroughly inspect all parts for any damage, with a keen focus on detecting cracks or damage in insulating porcelain bottles.

Verify the contact surface quality of the conductive part to ensure seamless operation.
