Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is expertly engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It's crafted to efficiently open and close single-phase or three-phase circuits where voltage is present, yet load is absent, ensuring seamless operation.

Tailored for single-phase applications within three-phase systems, this switch boasts simplicity, cost-efficiency, and user-friendliness. It offers versatile rated currents of 200, 400, 600, 800, 1000, and 1250 amps. Comprising a sturdy base, robust post insulators, reliable conductive elements, and a mechanical section, this switch excels in performance. Its innovative gate knife structure facilitates precise circuit opening and closing. Each phase's gate knife features dual conductive blades with external compression springs. Adjusting the spring height ensures optimal contact pressure for the gate knife, enhancing reliability. Operated with an insulated hook stick, it integrates a self-locking device for secure usage.

Optimal Working Environment:

Operates flawlessly at altitudes up to 1000 meters;

Withstands ambient temperatures ranging from a brisk -30°C to a balmy +40°C;

Designed for wind speeds not surpassing 35 meters/second;

Built to endure seismic activities up to 8 degrees, ensuring stable installation in regions free from frequent severe vibrations.

Deployed in environments devoid of harmful gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive agents that might compromise the switch's insulation and conductivity.

Important Consideration:

SHOULD NORMAL USE CONDITIONS BE EXCEEDED, USERS ARE ENCOURAGED TO NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

 

Installation, Usage, and Fine-Tuning Guidelines

Preparatory Steps Before Installation

1. Diligently cleanse all components to remove dust and debris, meticulously wiping the surface of the insulating porcelain bottle to preserve its integrity.
2. Thoroughly scrub the wiring interface of the ground screw for optimal conductivity.
3. Apply a protective layer of industrial Vaseline to the rotating and contact segments to ensure smooth operation.
4. Inspect the contact surfaces and fine-tune the compression spring height to meet the specified contact pressure as indicated in Table II.
5. Exclusively designed for hoisting applications, this switch works harmoniously with transformers along the line.
6. Rated for 200-400 amperes, it typically utilizes three mounting holes, whereas 600-1000A configurations also employ three mounting holes for secure attachment.

Annual Maintenance Checklist:
Clear all conductive parts, contact surfaces, and the insulating porcelain bottle's exterior of any accumulated dirt.

Inspect all components for potential damage, ensuring particular attention to the insulating porcelain bottle for any signs of damage or cracks.

Verify the good condition of the conductive part's contact surface.
