Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, often referred to as an isolation disconnect switch, is meticulously crafted for optimal performance on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This switch enables you to seamlessly open and close single-phase or three-phase circuits while maintaining voltage presence, ensuring reliability and safety.

This switch is expertly engineered for single-phase applications within three-phase line systems and stands out due to its straightforward design, cost-efficiency, and user-friendly operation. The switches accommodate rated currents of 200, 400, 600, 800, 1000, and 1250 amps. Each switch is composed of a robust base, durable post insulators, conductive components, and a sophisticated mechanical section. The advanced gate knife structure facilitates precise circuit opening and closing. Each phase's gate knife incorporates two conductive blades, flanked by external compression springs on both sides. By adjusting the spring height, you can attain the precise contact pressure necessary for optimal performance. Operation is executed using an insulated hook stick for seamless opening and closing actions, complemented by a self-locking device for enhanced safety.

Optimal Working Environment:

Altitude shall not surpass 1000 meters;

Ambient temperature shall remain below +40°C maximum and above -30°C minimum;

Outdoor wind velocity shall not exceed 35 meters per second;

Seismic intensity shall not surpass 8 degrees; installation sites should be free from frequent severe vibrations for maximum safety and reliability.

Installation sites must be devoid of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive substances that could severely impact the switch's insulation and conductivity.

Important Note:

WHEN CONDITIONS EXCEED NORMAL USE PARAMETERS, USERS MAY NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

 

Seamless Installation, Usage, and Adjustment

Essential Pre-installation Steps

1. Thoroughly remove any dust or dirt from all components and meticulously clean the surface of the insulating porcelain bottle for optimal performance.
2. Carefully scrub the wiring surface of the ground screw to ensure flawless connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas for smooth operation.
4. Inspect the contact surface and adjust the height of the compression spring to ensure contact pressure is in accordance with Table II specifications.
5. This switch is exclusively suitable for hoisting applications and is designed to be used in conjunction with the transformer on the line for unparalleled efficiency.
6. The switch's rated current spans 200-400 amperes hours, with typically three mounting holes utilized. Higher currents of 600-1000A similarly require three mounting holes for secure installation.

Conduct an Annual Inspection of the Following Switch Components:
Eliminate any dirt from conductive parts, contact surfaces, and the surfaces of insulating porcelain bottles for optimal conductivity and performance.

Examine all components for any signs of damage, paying special attention to the insulating porcelain bottle for any potential damage or cracks.

Verify the quality of the contact surface on all conductive parts to ensure consistent performance.
