Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is meticulously designed for impeccable performance on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It skillfully opens and closes single-phase or three-phase circuits without load, yet while voltage is present, ensuring seamless operation.

Engineered for single-phase use within three-phase line systems, this switch stands out for its streamlined structure, incredible cost-efficiency, and effortless usability. With an array of rated currents including 200, 400, 600, 800, 1000, and 1250 amps, this switch is versatile and adaptable. It is composed of a robust base, high-quality post insulators, reliable conductive parts, and an efficient mechanical section. The circuit is precisely controlled using a gate knife structure, where each phase's gate knife is crafted with two conductive blades and reinforced with external compression springs on both sides. Adjusting the spring height ensures the precise contact pressure needed for optimal performance. Operators can effortlessly open and close the switch using an insulated hook stick, benefiting from a dependable self-locking device for enhanced safety.

Working Environment:

Operational altitude should not exceed 1000 meters, ensuring optimal performance and reliability;

Ambient temperature: withstanding a maximum of +40°C and a minimum of -30°C, offering versatility in diverse climates;

Outdoor wind speeds should remain below 35 meters/second, guaranteeing stability against harsh winds;

Designed to withstand seismic intensity not to exceed 8 degrees, ensuring resilience during tremors. The installation site must remain stable without experiencing frequent severe vibrations.

The installation site should be free of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could severely compromise the switch's insulation and conductivity, preserving its longevity and functionality.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Ensure to thoroughly remove dust and dirt from all components and carefully clean the surface of the insulating porcelain bottle for optimal performance.
2. Scrub the wiring surface of the ground screw meticulously to ensure a solid, reliable connection.
3. Generously apply a layer of industrial Vaseline to rotating parts and contact areas to ensure smooth operation and longevity.
4. Inspect the contact surface diligently and adjust the height of the compression spring to ensure the contact pressure is in strict accordance with Table II specifications for peak performance.
5. This switch is exclusively designed for hoisting use and is intended to be used in conjunction with the transformer on the line, ensuring seamless integration.
6. With a rated current of 200-400 ampere-hours, typically, only three mounting holes are utilized, while 600-1000A configurations also utilize three mounting holes for secure, efficient installation.

Make it a priority to regularly check the following parts of the switch annually:
Meticulously remove dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to maintain optimal conductivity and performance.

Carefully inspect all parts for any signs of damage, with special attention to the insulating porcelain bottle, checking for damage and cracks to ensure reliability and safety.

Verify the quality of the contact surface of the conductive parts to ensure it remains in optimal condition for superior performance.
