Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, also recognized as an isolation disconnect switch, has been specifically engineered for use in 10(12, 15, 24)kV high voltage power transmission and distribution lines. This innovative switch facilitates the opening and closing of single-phase or three-phase circuits safely and effectively without the need to handle the load, even when voltage is present. It’s an essential component for ensuring seamless power management across various infrastructures.

This switch, crafted for single-phase application in three-phase line systems, stands out due to its uncomplicated design, affordability, and user-friendly operation. Choose from an impressive range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. The robust construction includes a base, post insulators, conductive parts, and a mechanical segment. Utilizing a gate knife structure, it efficiently manages circuit operations. Each phase’s gate knife is comprised of dual conductive blades, with external compression springs ensuring optimal performance. By adjusting the spring height, the necessary contact pressure is meticulously maintained. The switch is activated using an insulated hook stick, ensuring safe and secure operations, and features a dependable self-locking mechanism.

Working Environment:

Suitable for altitudes not exceeding 1000 meters;

Operable in ambient temperatures with a maximum of +40°C and a minimum of -30°C;

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

Designed to endure seismic intensities of up to 8 degrees, ensuring reliability at sites with minimal severe vibrations.

The installation environment should be free from gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive substances that could adversely affect the switch’s insulation and conductivity.

Note:

IF THE ABOVE STANDARD USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS ALTERNATIVE OPTIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove any dust and dirt from the components, and gently clean the surface of the insulating porcelain bottle to ensure optimal performance.
2. Carefully scrub the wiring surface of the ground screw for a clean and secure connection.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surfaces and make necessary adjustments to the height of the compression spring, ensuring the contact pressure aligns with the specifications in Table II.
5. This switch is specially designed for hoisting applications and is intended for use in conjunction with transformers on the line, ensuring reliable performance.
6. The switch is available with a rated current of 200-400 ampere hours, typically utilizing three mounting holes. For 600-1000A applications, three mounting holes are also employed.

Annual Maintenance: Regularly inspect the following components to ensure continued reliability and performance:
Thoroughly clean dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to maintain optimal conductivity and performance.

Inspect all parts for damage, with a particular focus on the insulating porcelain bottle for any signs of damage or cracking.

Ensure that the contact surface of the conductive part is in excellent condition, maintaining reliable connectivity.
