Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, often acclaimed as the isolation disconnect switch, is expertly engineered for seamless operation on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It adeptly opens and closes single-phase or three-phase circuits while sustaining voltage presence, ensuring uninterrupted operational efficiency.

This switch is meticulously crafted for single-phase use within three-phase line systems, lauded for its straightforward design, exceptional cost-effectiveness, and user-friendly functionality. Offered with a versatile range of rated currents—200, 400, 600, 800, 1000, and 1250 amps—these switches are an integration of a robust base, durable post insulators, high-quality conductive components, and a precision mechanical section. The innovative gate knife structure facilitates circuit operation, with each phase's gate knife incorporating dual conductive blades and external compression springs on both sides. By adjusting the spring height, the optimal contact pressure for the switch's gate knife is effortlessly achieved. Operation is simplified with an insulated hook stick for opening and closing actions, complemented by a secure self-locking device for enhanced safety.

Working Environment:

Altitude not exceeding 1000 meters;

Ambient temperature: maximum not above +40°C; minimum not below -30°C;

Outdoor wind speed not exceeding 35 meters/second;

Seismic intensity not exceeding 8 degrees; the installation site should not experience frequent severe vibrations.

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

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN NEGOTIATE WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Meticulously remove dust and dirt from all components, ensuring the insulating porcelain bottle's surface is impeccably clean.
2. Thoroughly scrub the wiring surface of the ground screw to ensure optimal contact.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to enhance performance and longevity.
4. Inspect the contact surface and make necessary adjustments to the compression spring height to ensure the contact pressure complies with Table II specifications.
5. This switch is exclusively designed for hoisting use in conjunction with transformers on the line, ensuring precise and efficient performance.
6. The rated current of this switch spans 200-400 ampere hours, generally utilizing three mounting holes for installation. For 600-1000A, three mounting holes are also used, ensuring stability and reliability.

Conduct a thorough annual check of the following switch components:
Carefully remove any dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' surface, maintaining optimal functionality.

Examine all parts for potential damage, giving particular attention to the integrity of the insulating porcelain bottle to detect any damage or cracks.

Ensure the contact surfaces of all conductive parts maintain excellent condition, preserving efficiency.
