Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, often referred to as an isolation disconnect switch, is meticulously crafted for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This innovative switch is adept at opening and closing single-phase or three-phase circuits without load, yet with voltage present, ensuring seamless operation.

This switch is specially engineered for single-phase applications within three-phase line systems. It boasts a straightforward design, remarkable affordability, and intuitive operation. The switch is available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps. Key components include a robust base, durable post insulators, conductive segments, and a mechanical assembly. The circuit is opened and closed utilizing a reliable gate knife mechanism, where each phase is equipped with dual conductive blades and external compression springs on both sides. The spring height can be adjusted to deliver optimal contact pressure for the gate knife. The switch is manipulated with an insulated hook stick for efficient opening and closing, featuring a dependable self-locking device for added safety.

Working Environment:

Recommended installation at altitudes not exceeding 1000 meters.

Ambient temperature range: maximum of +40°C and minimum of -30°C.

Capable of withstanding outdoor wind speeds up to 35 meters/second.

Designed to endure seismic intensity levels up to 8 degrees, ensuring stability in areas with minimal frequent severe vibrations.

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

Note:

SHOULD EXCEEDING NORMAL USE CONDITIONS OCCUR, USERS ARE ENCOURAGED TO DISCUSS OPTIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove any dust and debris from all 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 to ensure a solid connection.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation and longevity.
4. Inspect the contact surfaces and adjust the height of the compression spring to ensure that the contact pressure aligns with the specifications outlined in Table II.
5. This switch is exclusively designed for hoisting applications and is compatible with transformers on the line, enhancing operational efficiency.
6. With a rated current spanning from 200 to 400 ampere hours, this switch typically employs three mounting holes. For currents between 600 and 1000A, three mounting holes are similarly utilized to ensure stability.

Conduct an annual inspection of the following switch components:
Efficiently remove dirt from all conductive parts, contact surfaces, and the insulating porcelain bottle surface to maintain superior performance.

Meticulously examine all parts for signs of damage, with particular attention to the insulating porcelain bottle for potential damage or cracks.

Ensure that the contact surface of the conductive part maintains optimal condition.
