Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a pivotal component also identified as an isolation disconnect switch. Specifically engineered for 10(12, 15, 24)kV high voltage power transmission and distribution lines, this switch adeptly manages the opening and closing of single-phase or three-phase circuits. While it handles circuits that are not loaded, it operates seamlessly under the presence of voltage, ensuring efficient system control.

This switch is innovatively crafted for single-phase operation within three-phase line systems. It stands out with its straightforward design, cost-efficiency, and user-friendly nature. The switch offers a range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps, ensuring adaptability to diverse needs. Composed of a robust base, reliable post insulators, conductive components, and a precise mechanical section, it utilizes a gate knife structure for optimal circuit maneuvering. Each phase's gate knife features two effective conductive blades, supported by external compression springs on either side. By adjusting the spring height, the essential contact pressure for the gate knife is maintained. The switch's operation is simplified with an insulated hook stick for executing opening and closing actions, complemented by a self-locking device for increased safety and stability.

Working Environment:

Perfect for altitudes not exceeding 1000 meters;

Temperature resilience: operational in ambient temperatures with a maximum of +40°C; and can withstand cold climates with a minimum of -30°C;

Engineered to withstand outdoor wind speeds up to 35 meters/second;

Designed for seismic environments, with a tolerance for seismic intensity not exceeding 8 degrees; ideal for sites that do not experience frequent severe vibrations.

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

Note:

IF THE NORMAL USE CONDITIONS EXCEED THE SPECIFIED PARAMETERS, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY FOR CUSTOMIZED SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Prior to installation, ensure all components are free of dust and dirt, and meticulously clean the surface of the insulating porcelain bottle.
2. Thoroughly scrub the wiring surface of the ground screw for optimal conductivity.
3. Enhance the longevity and functionality of the rotating parts and contact areas by applying a layer of industrial Vaseline.
4. Inspect the contact surface diligently and adjust the compression spring height to ensure the contact pressure meets the specifications outlined in Table II.
5. This switch is meticulously designed for hoisting applications, ensuring seamless integration with transformers on the line.
6. The switch's rated current ranges from 200 to 400 ampere hours, generally utilizing three mounting holes. For 600-1000A applications, three mounting holes are standard for secure installation.

Conduct an annual check-up to ensure optimal performance of the switch. Focus on the following aspects:
Regularly remove any dirt from conductive parts, contact surfaces, and the insulating porcelain bottle surface to maintain efficiency.

Inspect all parts for potential damage, with a particular focus on detecting any damage or cracks in the insulating porcelain bottle.

Verify the integrity and quality of the contact surface of the conductive parts to ensure consistent performance.
