Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also elegantly referred to as an isolation disconnect switch, is meticulously engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It offers the precision of opening and closing single-phase or three-phase circuits under conditions where load is absent but voltage is present, ensuring safety and reliability.

This versatile switch is ideally crafted for single-phase application within three-phase line systems, boasting a straightforward design, affordability, and user-friendly operation. Its range of rated currents spans 200, 400, 600, 800, 1000, and 1250 amps, allowing for diverse electrical needs. The switch's architecture includes a robust base, durable post insulators, efficient conductive parts, and a precise mechanical section. A sophisticated gate knife configuration facilitates circuit engagement and disengagement, with each phase’s gate knife comprised of dual conductive blades flanked by external compression springs. The strategic adjustment of spring height ensures optimal contact pressure. Operational actions are performed with an insulated hook stick, supported by a self-locking mechanism for added security.

Working Environment:

Suitable for altitudes not exceeding 1000 meters;

Ideal ambient temperature ranges with a maximum of +40°C and a minimum of -30°C;

Capable of withstanding outdoor wind speeds up to 35 meters/second;

Designed to endure seismic intensities up to 8 degrees, with installation sites free from frequent severe vibrations.

The installation environment must be devoid of gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive mediums, to maintain the switch's insulation and conductivity integrity.

Note:

WHEN NORMAL USE CONDITIONS AS DESCRIBED ARE EXCEEDED, USERS ARE ENCOURAGED TO ENGAGE IN DIALOGUE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use, and Adjustment

Pre-installation work

1. Begin by meticulously removing dust and dirt from components, and gently cleaning the surface of the insulating porcelain bottle for optimal clarity and function.
2. Carefully scrub the wiring surface of the ground screw for perfect conductivity.
3. Apply a protective layer of industrial Vaseline to the rotating components and contact areas to ensure smooth operation.
4. Thoroughly inspect contact surfaces, adjusting the compression spring height as necessary to ensure contact pressure meets the standards outlined in Table II.
5. This switch is exclusively designed for hoisting use and complements transformer installations on the line seamlessly.
6. With a rated current capacity from 200 to 400 ampere hours, it typically requires three mounting holes, whereas, for 600-1000A, three mounting holes are also employed.

Conduct an annual inspection to ensure peak performance, focusing on the following components:
Diligently remove any dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to ensure seamless conductivity.

Examine all components for damage, with heightened attention to inspecting the insulating porcelain bottle for any signs of damage or cracks.

Verify that the contact surface of the conductive part remains impeccable.
