Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a pinnacle in electrical engineering excellence. Familiarly known as an isolation disconnect switch, this product is meticulously crafted for seamless operation on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It ensures flawless opening and closing of single-phase or three-phase circuits, maintaining voltage presence while effortlessly managing power flow without load.

Engineered for optimal performance in single-phase applications within three-phase line systems, this switch is the epitome of simplicity, economic design, and unparalleled usability. With rated currents from 200 to 1250 amps, it boasts components such as a robust base, durable post insulators, efficient conductive parts, and a precision mechanical section. The innovative gate knife structure facilitates smooth circuit engagement, with each phase featuring dual conductive blades enhanced by external compression springs. By fine-tuning the spring height, you achieve optimal contact pressure for the switch's gate knife. The switch’s operations are streamlined with an insulated hook stick, complemented by a reliable self-locking device for safety.

Working Environment:

Designed for altitudes not exceeding 1000 meters, ensuring optimal performance in diverse terrains;

Ambient temperature range maintained for reliability: maximum of +40°C and minimum of -30°C;

Resilient against outdoor wind speeds up to 35 meters/second, offering unwavering stability;

Engineered to withstand seismic intensities up to 8 degrees, with installation sites ideally free from frequent severe vibrations.

Installation sites must be devoid of harmful gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive mediums that could compromise the switch’s insulation and conductivity.

Note:

FOR CONDITIONS BEYOND THE NORMAL USE SPECIFICATIONS, USERS ARE ENCOURAGED TO DISCUSS ADAPTATIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Meticulously remove all dust and dirt from components, ensuring the insulating porcelain bottle surfaces are immaculate.
2. Thoroughly clean the wiring surface of the ground screw for optimal connectivity.
3. Apply industrial Vaseline generously to rotating parts and contact areas to enhance durability and performance.
4. Inspect the contact surface meticulously and adjust the compression spring height to meet the standards outlined in Table II, ensuring perfect contact pressure.
5. This switch is purpose-built for hoisting applications, designed to work harmoniously in conjunction with transformers on the line.
6. For rated currents of 200-400 ampere hours, the switch utilizes three mounting holes, with the same configuration applied to 600-1000A deployments.

Annually conduct a thorough inspection of the following switch components:
Diligently remove any accumulated dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to ensure pristine condition.

Examine all components meticulously for any signs of wear or damage, with a focused inspection on the insulating porcelain bottle to detect any potential damage or cracks.

Verify the integrity of the contact surface of all conductive parts to guarantee continual optimal performance.
