Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also recognized as an isolation disconnect switch, is meticulously crafted for deployment within 10(12, 15, 24)kV high voltage power transmission and distribution circuits. Engineered to open and close single-phase or three-phase circuits seamlessly, it performs these tasks without any load, but with voltage presence.

This advanced switch is tailored for single-phase use within three-phase line systems, celebrated for its uncomplicated design, affordability, and user-friendly operation. We offer rated currents of 200, 400, 600, 800, 1000, and 1250 amps, catering to diverse operational needs. The switch's architecture includes a base, post insulators, conductive components, and a mechanical section, leveraging a gate knife mechanism for circuit operations. Each phase's gate knife is composed of dual conductive blades, supplemented by external compression springs on either side. Adjusting these springs ensures optimal contact pressure for flawless switch operations. The switch operation is facilitated by an insulated hook stick and is equipped with a self-locking device for safety and reliability.

Working Environment:

Maximum altitude for operation: 1000 meters above sea level;

Ambient temperature range: Maximum of +40°C; Minimum of -30°C;

Permissible outdoor wind speed: up to 35 meters/second;

Seismic resistance: up to 8 degrees; The installation site should remain free from frequent intense vibrations.

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

Note:

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

 

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove dust and debris from all components, ensuring the insulating porcelain bottle's surface is gently wiped clean.
2. Clean the wiring surface of the grounding screw with care.
3. Apply a protective layer of industrial Vaseline to all rotating components and contact surfaces to ensure smooth operation.
4. Inspect the contact surfaces and adjust the compression spring's height to meet the specifications outlined in Table II, ensuring optimal contact pressure.
5. This switch is exclusively designed for hoisting applications, intended for use in conjunction with transformers on power lines.
6. The switch's rated current ranges from 200 to 400 amperes, with typical installation requiring three mounting holes. For 600-1000A, three mounting holes are similarly utilized.

Annual Maintenance: Please conduct a thorough inspection of the following components:
Clean conductive parts, contact surfaces, and the insulating porcelain bottle's surface to ensure optimal performance.

Examine all parts for any signs of damage, particularly inspecting the insulating porcelain bottle for cracks or other impairments.

Ensure that the conductive part's contact surfaces maintain excellent condition.
