Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, expertly engineered for optimal performance on 10(12, 15, 24)kV high-voltage power transmission and distribution lines. This isolation disconnect switch is adeptly crafted to open and close single-phase or three-phase circuits where voltage is present, yet requires no load handling. Experience unparalleled reliability and precision with this cutting-edge device.

Designed specifically for single-phase applications within three-phase line systems, this switch stands out with its straightforward architecture, cost-effectiveness, and user-friendly operation. It is available in a range of rated currents, including 200, 400, 600, 800, 1000, and 1250 amps, catering to diverse power needs. The switch's composition includes a robust base, dependable post insulators, conductive components, and a sophisticated mechanical section. Employing an innovative gate knife structure for circuit operations, each phase's gate knife features twin conductive blades, complemented by external compression springs for optimal contact pressure, adjustable via spring height. For seamless operation, an insulated hook stick is used, along with a self-locking mechanism that ensures secure handling.

Working Environment:

Suitable for installations at altitudes not exceeding 1000 meters;

Operates efficiently within an ambient temperature range: maximum +40°C; minimum -30°C;

Withstands outdoor wind speeds up to 35 meters/second;

Engineered to endure seismic intensity levels up to 8 degrees; ideal for locations free from frequent severe vibrations.

Designed for environments devoid of gases, chemical deposits, salt mist, dust, dirt, and any explosive or corrosive substances that could compromise the switch's insulation and conductivity.

Installation, Use and Adjustment

Pre-installation work

1. Initiate by removing dust and dirt from all components, meticulously cleaning the insulating porcelain bottle's surface for optimal performance.
2. Thoroughly scrub the wiring surface of the ground screw to ensure flawless electrical connections.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to enhance longevity and performance stability.
4. Inspect the contact surfaces diligently, adjusting the compression spring height to meet the precise contact pressure specifications detailed in Table II.
5. This switch is designed exclusively for hoisting applications and is intended for use in conjunction with transformers along the line.
6. The switch accommodates a rated current of 200-400 ampere hours, utilizing three mounting holes for standard installations. For 600-1000A applications, three mounting holes are implemented.

Annual Routine Inspection: Ensure optimal switch performance by conducting regular checks every year.
Meticulously clean dirt from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain peak efficiency.

Assess all components for potential damage, with a particular focus on inspecting the insulating porcelain bottle for any signs of damage or cracks.

Verify that the contact surfaces of the conductive parts remain in excellent condition.
