Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, an engineering marvel also known as an isolation disconnect switch, is meticulously crafted for optimal deployment on 10(12, 15, 24)kV high-voltage power transmission and distribution lines. It is designed to efficiently open and close single-phase or three-phase circuits seamlessly without load, while voltage remains present.

This ingenious switch, tailored for single-phase application in three-phase line systems, boasts a straightforward design, unparalleled cost-effectiveness, and user-friendly operation. The diverse range of available rated currents includes 200, 400, 600, 800, 1000, and 1250 amps, making it versatile for various applications. The switch comprises a robust base, sturdy post insulators, conductive components, and a precision-engineered mechanical section. Employing an innovative gate knife structure for effective circuit management, each phase's gate knife includes two conductive blades flanked by external compression springs. Precise adjustment of spring height ensures the switch's gate knife maintains optimal contact pressure. Operation is effortlessly executed with an insulated hook stick, complemented by a reliable self-locking mechanism.

Working Environment:

Operative at altitudes not exceeding 1000 meters, ensuring reliability in diverse terrains;

Capable of enduring ambient temperatures, with a maximum not above +40°C and a minimum not below -30°C, maintaining functionality in extreme climates;

Designed to withstand outdoor wind speeds of up to 35 meters/second, assuring steadfast performance in windy conditions;

Tested for seismic intensity not exceeding 8 degrees; the installation site should remain untroubled by frequent severe vibrations, ensuring stability and durability.

The installation venue must be free from gases, chemical residues, salt mist, dust, dirt, or any other explosive or corrosive substances that could impair the switch's insulation and conductivity, safeguarding its performance.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO NEGOTIATE WITH THE COMPANY TO DISCUSS SUITABLE ALTERNATIVES.

 

Installation, Use and Adjustment

Pre-installation work

1. Ensure all components are pristine by removing dust and grime, and meticulously wiping the insulating porcelain bottle's surface for optimal performance.
2. Thoroughly clean the wiring surface of the ground screw to guarantee secure electrical connectivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to minimize wear and enhance longevity.
4. Meticulously inspect contact surfaces and adjust the compression spring's height, ensuring contact pressure aligns with Table II specifications for impeccable operation.
5. This switch is specially designed for hoisting applications, seamlessly integrating with the transformer on the line for enhanced utility.
6. With a rated current of 200-400 ampere hours, it typically employs three mounting holes; for 600-1000A, three mounting holes are utilized for secure installation.

Conduct an annual inspection of the following switch components to ensure continued reliability:
Diligently remove any dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' exterior to maintain pristine condition.

Examine all components for potential damage, placing special emphasis on inspecting the insulating porcelain bottle for any signs of damage or cracks.

Verify that the contact surface of the conductive part remains in excellent condition for uninterrupted functionality.
