Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, truly a marvel of engineering, is expertly crafted for seamless use on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It offers the capability to efficiently open and close single-phase or three-phase circuits without load, yet with voltage present, ensuring reliable performance.

Designed for single-phase utilization within three-phase line systems, this switch stands out with its elegantly simple structure, unparalleled cost-effectiveness, and user-friendly operation. It is available in an impressive range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. The switch is composed of a sturdy base, reliable post insulators, conductive parts, and a robust mechanical section. Its gate knife structure facilitates smooth circuit operations. Each phase is equipped with a gate knife consisting of two conductive blades, complemented by external compression springs on either side. By adjusting the spring height, optimal contact pressure for the gate knife is achieved. Operating the switch is a breeze, thanks to the insulated hook stick used for opening and closing actions, and it boasts a convenient self-locking device.

Working Environment:

Altitude: Safely operates at heights not exceeding 1000 meters.

Ambient Temperature: Capable of withstanding a maximum of +40°C and a minimum of -30°C, ensuring functionality across diverse climates.

Wind Speed: Designed to function smoothly in conditions where outdoor wind speeds do not exceed 35 meters/second.

Seismic Intensity: Built to endure seismic activities up to 8 degrees, provided the installation site is free from frequent severe vibrations.

The installation site must remain free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that could compromise the switch's insulation and conductivity efficiency.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN NEGOTIATE WITH THE COMPANY to tailor solutions that meet specific needs.

 

Installation, Use and Adjustment

Pre-installation Work

1. Ensure all parts are pristine by removing dust and dirt, meticulously wiping the insulating porcelain bottle surface for optimum performance.
2. Thoroughly scrub the wiring surface of the ground screw to ensure perfect conductivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to maintain smooth operation.
4. Inspect the contact surface and precisely adjust the compression spring height to align with the specifications in Table II, ensuring flawless contact pressure.
5. This switch is intended exclusively for hoisting applications, designed for seamless integration with transformers on the line.
6. With a rated current of 200-400 ampere hours, typically only three mounting holes are used. For 600-1000A applications, three mounting holes are standard.

Conduct Regular Annual Checks on the following switch components:
Diligently remove dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain optimal operation.

Examine all parts for any signs of damage, focusing especially on detecting damage or cracks in the insulating porcelain bottle.

Ensure the contact surfaces of the conductive parts remain in excellent condition.
