Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is meticulously engineered for seamless operation on 10(12, 15, 24)kV high-voltage power transmission and distribution lines. It proficiently opens and closes single-phase or three-phase circuits without load but with voltage present, ensuring safe and reliable isolation.

Ideal for single-phase applications in three-phase line systems, this switch stands out for its straightforward design, cost-efficiency, and user-friendly operation. It caters to various rated currents, available in 200, 400, 600, 800, 1000, and 1250 amps. The switch comprises a robust base, post insulators, highly conductive parts, and a mechanical section for reliability. A sophisticated gate knife structure enables efficient circuit control. Each phase's gate knife is equipped with dual conductive blades and external compression springs on both sides. Spring height adjustments ensure optimal contact pressure. Operations are conducted using an insulated hook stick, featuring a self-locking device for added safety.

Working Environment:

Altitude should not exceed 1000 meters;

Ambient temperature: maximum should not surpass +40°C; minimum should not drop below -30°C;

Outdoor wind speed should not exceed 35 meters/second;

Seismic intensity not exceeding 8 degrees; the installation site must be free from frequent severe vibrations.

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

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO NEGOTIATE WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Diligently remove dust and dirt from all components, ensuring the surface of the insulating porcelain bottle is meticulously cleaned.
2. Thoroughly scrub the wiring surface of the ground screw to ensure optimal conductivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surface and carefully adjust the height of the compression spring to meet the specifications outlined in Table II.
5. This switch is exclusively designed for hoisting applications and is intended for use with transformers on the line.
6. The switch's rated current is between 200-400 ampere hours, typically requiring only three mounting holes. For 600-1000A, three mounting holes are also used.

Conduct a thorough annual inspection of the following switch components:
Remove any accumulated dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to maintain peak performance.

Inspect all parts for damage, with a focus on checking the insulating porcelain bottle for any damage or cracks.

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