Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation disconnect switch is an engineering marvel, meticulously crafted for optimal use in 10(12, 15, 24)kV high voltage power transmission and distribution lines. This robust and reliable switch excels in opening and closing single-phase or three-phase circuits without load while the voltage is present, ensuring seamless operation and unwavering performance.

This exceptional switch is tailored for single-phase applications within three-phase line systems, boasting simplicity, affordability, and user-friendliness. Choose from a variety of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. Each switch is a harmonious assembly of a sturdy base, reliable post insulators, efficient conductive parts, and an adept mechanical section. Its innovative gate knife structure facilitates smooth circuit operations. Each phase's gate knife embodies dual conductive blades complemented by external compression springs on both sides. By adjusting the spring height, the essential contact pressure for the switch's gate knife is achieved. The switch is effortlessly operated with an insulated hook stick for opening and closing maneuvers and includes a dependable self-locking device to ensure stability.

Working Environment:

Altitude: ceiling height of 1000 meters;

Ambient temperature: cap at +40°C; dip at -30°C;

Outdoor wind velocity capped at a robust 35 meters/second;

Seismic intensity: no more than 8 degrees; installation zones should be free from frequent and severe vibrations.

The installation site must be devoid of gases, chemical deposits, salt mist, dust, dirt, and any explosive or corrosive mediums that may severely compromise the insulation and conductivity of the switch.

Note:

WHEN CONDITIONS SURPASS NORMAL PARAMETERS, THE USER HAS THE OPTION TO NEGOTIATE WITH THE COMPANY.

 

Installation, Use and Adjustment

Pre-installation work

1. Eliminate any dust and dirt from the components, ensuring the insulating porcelain bottle is meticulously wiped clean.
2. Thoroughly clean the wiring surface of the ground screw.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas, ensuring seamless movement.
4. Inspect the contact surface and fine-tune the height of the compression spring to ensure the contact pressure aligns with Table II specifications.
5. This switch is exclusively designed for hoisting applications and is ideally paired with a transformer on the line.
6. For rated currents of 200-400 ampere hours, three mounting holes are generally utilized. The 600-1000A range also employs three mounting holes for optimal installation.

Annual Inspection Checklist:
Remove accumulated dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's surface.

Conduct a meticulous examination of all components for damage, with particular focus on the insulating porcelain bottle for any signs of damage or cracks.

Ensure the contact surface of the conductive part maintains optimal condition.
