Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, commonly 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 cutting-edge switch enables the seamless opening and closing of single-phase or three-phase circuits, even under voltage, but without load.

Tailored for single-phase applications in three-phase line systems, this switch stands out with its streamlined design, affordability, and user-friendly operation. It is available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps. The switch integrates a robust base, post insulators, conductive elements, and a mechanical section. Utilizing a sophisticated gate knife mechanism, it ensures efficient circuit engagement and disengagement. Each phase's gate knife comprises dual conductive blades equipped with external compression springs. By adjusting the spring height, optimal contact pressure for the gate knife is achieved. Operation involves an insulated hook stick, and a self-locking device enhances security.

Working Environment:

Altitude should not exceed a majestic 1000 meters;

Ambient temperature range: a sweltering maximum of +40°C to a chilly minimum of -30°C;

Outdoor wind velocity: a maximum of 35 meters/second;

Seismic intensity must be kept under 8 degrees, and the installation site should be free from frequent intense vibrations.

The installation site must be devoid of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive substances that could severely impact the switch's insulation and conductivity.

Note:

WHEN THESE NORMAL USAGE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS WITH THE COMPANY FOR SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Carefully eliminate dust and dirt from all components, ensuring the insulating porcelain bottle shines brilliantly.
2. Meticulously scrub the wiring surface of the ground screw to guarantee immaculate contact.
3. Apply a fine layer of industrial Vaseline to all rotating parts and contact areas for smooth operation.
4. Examine the contact surface and finetune the compression spring height to ensure contact pressure aligns with Table II.
5. Specifically designed solely for hoisting, this switch is intended for use alongside transformers on the line.
6. With a rated current ranging between 200-400 ampere hours, three mounting holes are generally utilized. For 600-1000A applications, three mounting holes are employed.

Annually conduct thorough checks on the switch components:
Diligently remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottles.

Inspect every part for potential damage, placing special emphasis on detecting damage or cracks in the insulating porcelain bottle.

Verify the integrity of the conductive part's contact surface to maintain optimal conductivity.
