Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, affectionately known as an isolation disconnect switch, is expertly crafted for seamless operation on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It serves the purpose of opening and closing both single-phase and three-phase circuits without load but with voltage present, ensuring a robust and reliable system.

This remarkable switch is meticulously designed for single-phase applications within three-phase line systems, boasting a simple yet ingenious structure, making it both cost-effective and user-friendly. It offers a range of rated currents including 200, 400, 600, 800, 1000, and 1250 amps, catering to various demands. The switch is composed of a sturdy base, durable post insulators, high-quality conductive parts, and a precise mechanical section. It utilizes an innovative gate knife structure to facilitate circuit operations. The gate knife of each phase elegantly consists of two conductive blades, reinforced by external compression springs on both sides. By adjusting the spring height, the necessary contact pressure is effortlessly achieved for the switch's gate knife. The switch operation is elegantly managed with an insulated hook stick for seamless opening and closing actions, further enhanced by a reliable self-locking device.

Working Environment:

Altitude not exceeding 1000 meters; ensuring functionality in elevated terrains.

Ambient temperature: maximum not above +40°C; minimum not below -30°C; suitable for diverse climatic conditions.

Outdoor wind speed not exceeding 35 meters/second; designed to withstand strong winds.

Seismic intensity not exceeding 8 degrees; installations should be in areas free from frequent severe vibrations, ensuring sustained stability.

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

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Meticulously remove dust and dirt from all components, and carefully cleanse the surface of the insulating porcelain bottle to ensure pristine conditions.
2. Thoroughly 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 maintain smooth operation.
4. Inspect contact surfaces and adjust the height of the compression spring to meet the specified contact pressure in Table II, ensuring optimal performance.
5. This switch is intended exclusively for hoisting applications and works in perfect harmony with the transformer on the line, delivering exceptional functionality.
6. The rated current of this switch ranges from 200-400 ampere hours, typically requiring only three mounting holes. For 600-1000A applications, three mounting holes are employed for robust support.

Conduct a meticulous annual check of the following switch components:
Thoroughly remove dirt from the conductive parts, contact surfaces, and the surface of insulating porcelain bottles, maintaining their integrity.

Inspect all parts for any damage, giving special attention to the insulating porcelain bottle to detect any damage or cracks promptly.

Verify that the contact surface of the conductive part is in excellent condition, ensuring seamless performance.
