Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, also renowned as an isolation disconnect switch, is meticulously crafted to function seamlessly on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It flawlessly opens and closes single-phase or three-phase circuits while maintaining voltage presence, though without load.

Engineered for single-phase deployment within three-phase line systems, this switch boasts a straightforward design, offering both cost-efficiency and user-friendly operation. Its rated current options include 200, 400, 600, 800, 1000, and 1250 amps. Comprising a robust base, high-quality post insulators, conductive components, and a mechanical section, it employs a gate knife structure to effectively open and close circuits. Each phase's gate knife features dual conductive blades with external compression springs on each side to ensure optimal contact pressure, adjustable via spring height. The switch is effortlessly maneuvered with an insulated hook stick for operational actions, complemented by a reliable self-locking mechanism.

Working Environment:

Ideal for altitudes not exceeding 1000 meters;

Capable of withstanding ambient temperatures up to a maximum of +40°C and a minimum of -30°C;

Resilient to outdoor wind speeds not surpassing 35 meters/second;

Designed to endure seismic intensities not beyond 8 degrees, ensuring stable installation in sites free from frequent severe vibrations.

The ideal installation site should be devoid of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could severely impact the switch’s insulation and conductivity.

Note:

WHEN THE SPECIFIED NORMAL USE CONDITIONS ARE SURPASSED, USERS ARE ENCOURAGED TO NEGOTIATE WITH THE COMPANY FOR CUSTOM SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove dust and dirt from all components and meticulously wipe the insulating porcelain bottle's surface to ensure cleanliness.
2. Carefully scrub the wiring surface of the ground screw to ensure optimal conductivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas for enhanced durability and performance.
4. Inspect the contact surfaces and adjust the compression spring's height to ensure the contact pressure meets the standards outlined in Table II.
5. This switch is exclusively suitable for hoisting use and is ingeniously designed for complementing the transformer on the line.
6. The switch is rated for a current of 200-400 ampere hours, typically employing three mounting holes. For 600-1000A, three mounting holes are utilized.

Conduct an annual inspection of the following switch components:
Thoroughly clean dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' surface to maintain excellent performance.

Inspect all components for damage, particularly focusing on identifying any damage or cracks in the insulating porcelain bottle.

Verify that the contact surface of the conductive part remains in optimal condition.
