Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, or isolation disconnect switch, is meticulously engineered for effortless integration on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is adept at safely opening and closing single-phase or three-phase circuits under voltage but without load, ensuring reliable and efficient operation.

This switch is expertly crafted for single-phase applications within three-phase line systems, boasting a straightforward design that emphasizes cost-effectiveness and user-friendliness. Featuring a range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps, each switch is composed of a sturdy base, durable post insulators, robust conductive parts, and a precision mechanical section. Employing a gate knife structure, it simplifies circuit management, with each phase's gate knife incorporating two conductive blades aided by external compression springs. Adjusting the springs finely tunes the contact pressure to optimal levels. This switch is operated via an insulated hook stick and includes a self-locking mechanism for secure operations.

Working Environment:

Ideal for altitudes not surpassing 1000 meters;

Capable of withstanding ambient temperatures: maximum +40°C; minimum -30°C;

Designed for environments where outdoor wind speeds do not exceed 35 meters/second;

Resilient to seismic intensities up to 8 degrees, suitable for sites with minimal severe vibration occurrences.

The installation site must be free from gases, chemical deposits, salt mist, and other contaminants that could compromise the switch's insulation and conductivity.

Note:

IF NORMAL USE CONDITIONS ARE EXCEEDED, USERS MAY ENGAGE IN DISCUSSIONS WITH THE COMPANY TO EXPLORE CUSTOMIZED SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Ensure all parts are free from dust and dirt, and meticulously clean the exterior of the insulating porcelain bottle.
2. Thoroughly scrub the ground screw's wiring surface to maintain optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating components and contact areas to enhance longevity.
4. Examine the contact surfaces and adjust the compression spring height to meet the specifications outlined in Table II, ensuring proper contact pressure.
5. This switch is exclusively designed for hoisting use, seamlessly integrating with the transformer on the line for enhanced functionality.
6. The switch accommodates a rated current of 200-400 ampere hours with three mounting holes; for 600-1000A applications, three mounting holes are typically used for secure installation.

Conduct an annual inspection of the switch, focusing on the following parts:
Remove any accumulated dirt from conductive parts, contact surfaces, and the insulating porcelain bottles.

Inspect all components for damage, paying particular attention to the insulating porcelain bottle for any signs of damage or cracking.

Verify the integrity of the conductive part's contact surface to ensure seamless connectivity.
