Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, an ingenious solution also known as the isolation disconnect switch. This marvel is engineered to serve on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It's adept at seamlessly opening and closing single-phase or three-phase circuits without load, yet with voltage present, ensuring reliability and precision.

Crafted for excellence in single-phase use within three-phase line systems, this switch boasts a simple structure, affordability, and user-friendliness. With rated currents spanning 200, 400, 600, 800, 1000, and 1250 amps, it is versatile in its applications. Constructed from a foundational base, post insulators, conductive components, and a mechanical section, it employs a sophisticated gate knife structure for circuit transitions. Each phase's gate knife consists of two conductive blades, enhanced by external compression springs on either side. These springs can be adjusted in height to secure the ideal contact pressure for optimal function. The switch is operated effortlessly with an insulated hook stick, complemented by a self-locking device for secure handling.

Working Environment:

Ideal for altitudes not exceeding 1000 meters; ensuring top performance at high elevations.

Designed for ambient temperatures with a maximum of +40°C and a minimum of -30°C, adapting to extreme weather conditions.

Efficiently handles outdoor wind speeds up to 35 meters/second, maintaining stability in windy conditions.

Built to withstand seismic activities up to 8 degrees, this switch should be installed in locations free from frequent intense vibrations.

The installation environment should be free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that could adversely affect the switch's insulation and conductivity, ensuring durability and safety.

Note:

IF THE ABOVE NORMAL USE CONDITIONS ARE SURPASSED, USERS ARE ENCOURAGED TO NEGOTIATE WITH THE COMPANY FOR FURTHER ASSISTANCE.

Installation, Use and Adjustment

Pre-installation work

1. Ensure all components are pristine by removing any dust and dirt. Carefully clean the surfaces of the insulating porcelain bottles for optimal performance.
2. Diligently scrub the wiring surface of the ground screw to ensure flawless connectivity.
3. Apply a generous layer of industrial Vaseline to the rotating parts and contact areas to guarantee smooth operation and longevity.
4. Thoroughly inspect the contact surfaces and adjust the compression spring heights to meet the specifications outlined in Table II.
5. This switch is designed exclusively for hoisting applications and is intended for seamless integration with transformers on the line.
6. With a rated current of 200-400 ampere hours, the switch typically utilizes three mounting holes. For 600-1000A applications, three mounting holes are standard.

Annually inspect the switch to maintain its peak performance and safety.
Meticulously clean the conductive parts, contact surfaces, and insulating porcelain bottles, removing any accumulation of dirt and debris.

Conduct a comprehensive review of all components for any signs of damage, paying special attention to the insulating porcelain bottles for any cracks or defects.

Verify that the contact surfaces of the conductive parts remain in excellent condition, ensuring seamless conductivity.
