Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, the reliable isolation disconnect switch, is expertly crafted for 10(12, 15, 24)kV high voltage power transmission and distribution lines, allowing seamless opening and closing of single-phase or three-phase circuits with voltage present.

This switch is designed specifically for single-phase applications in three-phase line systems and is lauded for its straightforward structure, affordability, and user-friendliness. Available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps, these switches comprise a robust base, durable post insulators, conductive components, and a mechanical section. The innovative gate knife design facilitates circuit opening and closing, with each phase's gate knife featuring dual conductive blades and external compression springs for optimal contact pressure adjustment. The switch can be operated using an insulated hook stick for reliable opening and closing and is equipped with a secure self-locking mechanism.

Working Environment:

Operates efficiently at altitudes not exceeding 1000 meters;

Thrives in ambient temperatures, with a maximum not exceeding +40°C and a minimum not dropping below -30°C;

Performs reliably in outdoor wind speeds up to 35 meters/second;

Designed to withstand seismic intensities not exceeding 8 degrees, with installation sites free from frequent severe vibrations.

Installation sites must be free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive elements that could significantly impact the switch's insulation and conductivity.

Note:

SHOULD THE ABOVE NORMAL USE CONDITIONS BE SURPASSED, USERS MAY ENGAGE IN NEGOTIATIONS WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Meticulously clear dust and debris from all parts, ensuring the insulating porcelain bottle surface is thoroughly cleaned.
2. Diligently scrub the wiring surface of the ground screw to ensure optimal contact.
3. Coat the rotating parts and contact areas with a protective layer of industrial Vaseline.
4. Examine the contact surface attentively and adjust the compression spring height to align with the precise contact pressure outlined in Table II.
5. Engineered exclusively for hoisting applications, this switch is effectively used in tandem with transformers along the line.
6. The switch's rated current ranges from 200-400 ampere hours, typically requiring three mounting holes, while 600-1000A configurations also utilize three mounting holes.

Conduct an annual inspection of the following switch components to ensure peak performance:
Diligently remove dirt from conductive parts, contact surfaces, and the insulating porcelain bottle's exterior.

Conduct a comprehensive inspection for any damage, particularly focusing on the insulating porcelain bottle to identify potential damages or cracks.

Assess the contact surface of conductive parts to ensure they maintain optimal condition.
