Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is masterfully engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is adept at opening and closing single-phase or three-phase circuits where there is no load, yet voltage is present.

This switch is meticulously designed for single-phase application within three-phase line systems, and stands out with its straightforward structure, economic viability, and effortless operation. It offers a range of rated currents including 200, 400, 600, 800, 1000, and 1250 amps. Comprising a base, post insulators, conductive components, and a mechanical assembly, it uses a gate knife configuration for circuit operations. Each phase's gate knife consists of two conductive blades, complemented by external compression springs on both sides. By adjusting the spring height, optimal contact pressure for the switch's gate knife is ensured. Operations are conducted with an insulated hook stick for seamless opening and closing, further enhanced by a self-locking mechanism.

Working Environment:

Designed for altitudes not exceeding an impressive 1000 meters;

Capable of withstanding ambient temperatures with a maximum of +40°C and a minimum of -30°C;

Built to endure outdoor wind speeds not surpassing 35 meters per second;

Engineered to withstand seismic intensity up to 8 degrees with the installation site being free from frequent and severe vibrations.

The installation site must be devoid of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive elements that could significantly impact the switch’s insulation and conductivity.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN ENTER INTO DISCUSSIONS WITH THE COMPANY TO EXPLORE POSSIBLE SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Initiate by meticulously removing dust and dirt from all components, while carefully wiping the insulating porcelain bottle's surface to ensure optimal performance.
2. Thoroughly scrub the wiring surface of the ground screw to maintain excellent conductivity.
3. Apply a protective layer of industrial Vaseline on rotating parts and contact areas to enhance smooth operations and prevent wear.
4. Inspect the contact surface and adjust the compression spring height accordingly to ensure it meets the standards detailed in Table II.
5. This switch is exclusively designed for hoisting applications and is intended for use in tandem with the transformer on the line.
6. The rated current of this switch covers 200-400 amperes, facilitating the use of three mounting holes, while the 600-1000A range also utilizes three mounting holes for secure installation.

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

Examine all parts for potential damage, with particular attention to the insulating porcelain bottle to detect any cracks or structural weaknesses.

Ensure that the contact surface of the conductive part remains in pristine condition.
