Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a marvel of engineering often referred to as an isolation disconnect switch. Specifically crafted for 10(12, 15, 24)kV high voltage power transmission and distribution lines, this switch performs the critical function of safely opening and closing single-phase or three-phase circuits. It is engineered to handle voltage with finesse, even as it operates without load. This state-of-the-art switch ensures seamless operation on complex electrical systems, with unmatched reliability and precision.

Designed for excellence in single-phase use within three-phase line systems, this switch stands out for its simplicity, cost-effectiveness, and user-friendliness. It offers a versatile range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps, catering to diverse operational needs. The switch comprises a robust base, high-quality post insulators, conductive components, and a sophisticated mechanical section. The innovative gate knife structure ensures flawless circuit engagement and disengagement. Each phase's gate knife is equipped with dual conductive blades and external compression springs, allowing precise adjustment of spring height for optimal contact pressure. The switch's operation is facilitated by an insulated hook stick, complemented by a secure self-locking device for enhanced safety and efficiency.

Working Environment

Ideal operating conditions at altitudes not exceeding 1000 meters;

Thrives within an ambient temperature range: a maximum of +40°C and a minimum of -30°C;

Designed to withstand outdoor wind speeds of up to 35 meters per second;

Built to endure seismic intensity levels up to 8 degrees, ensuring stability even in less-than-ideal conditions; installation sites should be free from frequent severe vibrations.

For optimal performance, ensure the installation site is free from gases, chemical deposits, salt mist, dust, dirt, and other explosive or corrosive elements that could compromise the switch's insulation and conductivity.

Note:

In circumstances where conditions exceed the normal parameters, we encourage users to engage in discussions with our company for bespoke solutions.

Installation, Use, and Adjustment

Pre-installation Preparations

1. Meticulously eliminate dust and dirt from components and ensure the insulating porcelain bottle's surface is impeccably clean.
2. Diligently clean the grounding screw's wiring surface to promote optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation and longevity.
4. Examine the contact surface meticulously and adjust the compression spring's height to maintain the contact pressure as specified in Table II.
5. This switch is exclusively designed for hoisting applications, ideally used in conjunction with transformers within the line.
6. With a rated current spanning 200-400 ampere hours, the design typically utilizes three mounting holes, which is consistent for currents up to 1000A.

Annual Maintenance Checklist: Ensure Optimal Functionality
Regularly remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottle to ensure optimal conductivity and performance.

Thoroughly inspect all components for potential damage, paying particular attention to the insulating porcelain bottle for any signs of damage or cracks.

Verify the integrity of the conductive part's contact surface to ensure smooth operation.
