Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a pinnacle of engineering excellence in the realm of electrical power solutions. Also known as an isolation disconnect switch, it is meticulously crafted for seamless integration into 10(12, 15, 24)kV high voltage power transmission and distribution lines. This advanced switch facilitates the opening and closing of single-phase or three-phase circuits effortlessly, even in the presence of voltage, yet without load.

Engineered for optimal performance in single-phase applications within three-phase line systems, our switch stands out for its streamlined design, economic efficiency, and user-friendly operation. Choose from a range of rated currents including 200, 400, 600, 800, 1000, and 1250 amps to perfectly match your needs. Each switch is composed of a robust base, durable post insulators, conductive components, and a highly reliable mechanical section. The innovative gate knife structure ensures precision in circuit operations. Each phase's gate knife features dual conductive blades enhanced with external compression springs for superior performance. Fine-tune the spring height to secure adequate contact pressure. Operation is a breeze with an insulated hook stick, and a self-locking device ensures safety and reliability.

Working Environment:

Designed for installation in locations with an altitude not exceeding 1000 meters;

Capable of withstanding ambient temperatures, with a maximum threshold of +40°C and a minimum resilience of -30°C;

Efficiently operates in outdoor environments where wind speeds do not surpass 35 meters/second;

Engineered to endure seismic intensities up to 8 degrees, ensuring stability at sites free from frequent severe vibrations.

Positioned in safe environments, the installation site must be devoid of gases, chemical deposits, salt mist, dust, dirt, and any explosive or corrosive mediums that could compromise the switch's insulation and conductivity.

Note:

IN CASE THE STANDARD OPERATING CONDITIONS ARE SURPASSED, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly eliminate dust and debris from all components, paying special attention to cleansing the insulating porcelain bottle's surface to maintain immaculate standards.
2. Ensure the wiring surface of the ground screw is pristine by giving it a careful scrub.
3. Coat rotating parts and contact areas with a fine layer of industrial Vaseline to enhance longevity and performance.
4. Inspect contact surfaces meticulously and adjust the height of the compression spring to ensure contact pressure aligns with specifications in Table II.
5. This switch is ideally suited for hoisting applications and is designed to operate in conjunction with transformers along the line.
6. The switch, rated at 200-400 ampere hours, typically requires only three mounting holes, whereas models rated 600-1000A also utilize three mounting holes for optimal stability.

A comprehensive annual inspection checklist includes the following tasks:
Meticulously clean dirt from all conductive parts, contact surfaces, and the exterior of insulating porcelain bottles, ensuring optimal function.

Vigilantly assess all components for any signs of damage, particularly inspecting the insulating porcelain bottle for wear or cracks.

Verify the integrity of the contact surface within the conductive part to guarantee excellence in performance.
