Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is meticulously engineered for unparalleled performance on high voltage power transmission and distribution lines of 10(12, 15, 24)kV. This essential device serves to seamlessly open and close single-phase or three-phase circuits under the presence of voltage yet without load. Its robust and reliable design makes it an ideal choice for diverse power network applications.

Tailored for single-phase utilization within three-phase line systems, this switch is distinguished by its simple yet effective structure, affordability, and user-friendly operation. Offered in a range of rated currents, including 200, 400, 600, 800, 1000, and 1250 amps, it is constructed with a durable base, strong post insulators, integral conductive parts, and a precision-engineered mechanical section. The innovative gate knife mechanism, featuring dual conductive blades and external compression springs, ensures optimal contact pressure through adjustable spring height. Operable via an insulated hook stick, this switch also incorporates a self-locking device for enhanced safety and functionality.

Working Environment:

Altitude must not surpass 1000 meters;

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

Outdoor wind speeds must remain below 35 meters per second;

The seismic intensity should not exceed 8 degrees, and the installation site must be free of frequent severe vibrations.

The installation area must be devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that may severely impact the switch's insulation and conductivity, ensuring optimal performance and longevity.

Note:

WHEN THE NORMAL OPERATING CONDITIONS MENTIONED ABOVE ARE EXCEEDED, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY FOR POSSIBLE SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly cleanse the switch components of dust and dirt, and meticulously wipe the surfaces of the insulating porcelain bottles to maintain their insulating integrity.
2. Clean the wiring surface of the ground screw to ensure optimal conductivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to enhance their longevity and performance.
4. Inspect the contact surface meticulously and adjust the compression spring height to ensure the contact pressure adheres to the specifications outlined in Table II.
5. This switch is specifically designed for hoisting applications and is intended to be used in conjunction with transformers on the line for efficient power distribution.
6. With a rated current range of 200-400 amperes, the switch typically utilizes three mounting holes, while the 600-1000 ampere variants also adopt three mounting holes for secure and stable installation.

Ensure regular annual inspections of the following switch components:
Diligently remove any accumulated dirt from the conductive components, contact surfaces, and insulating porcelain bottle surfaces to maintain optimal electrical performance.

Examine all components carefully for any signs of damage, giving special attention to the insulating porcelain bottles for potential damage or cracking.

Verify the condition of the contact surfaces within the conductive parts to ensure excellent connectivity and performance.
