Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is meticulously engineered for application on 10(12, 15, 24)kV high voltage power transmission and distribution lines. Specifically, it serves to efficiently open and close single-phase or three-phase circuits while ensuring voltage presence without load, maximizing safety and performance.

Our switch is designed primarily for single-phase use within three-phase line systems and stands out for its uncomplicated structure, cost-efficiency, and user-friendly operation. It offers a range of rated currents including 200, 400, 600, 800, 1000, and 1250 amps, tailored to meet diverse needs. The sophisticated construction consists of a robust base, reliable post insulators, conductive components, and a precise mechanical section. Utilizing a refined gate knife structure, the switch efficiently manages circuit operations. Each phase's gate knife features dual conductive blades, supported by external compression springs on either side. Precision in spring height adjustment ensures optimal contact pressure for the gate knife's seamless operation. The switch's opening and closing are conveniently executed with an insulated hook stick, complemented by an integrated self-locking device to enhance security and reliability.

Working Environment:

Installation is optimal at altitudes not exceeding 1000 meters;

Ambient temperature parameters: a maximum of +40°C, with a minimum threshold of -30°C;

Designed to withstand outdoor wind speeds of up to 35 meters per second;

Engineered to endure seismic intensity levels not surpassing 8 degrees, with the installation site ideally free from frequent severe vibrations.

The site of installation should remain clear of gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive elements that could significantly impair the switch's insulating and conductive capabilities.

Note:

WHEN STANDARD OPERATING CONDITIONS ARE EXCEEDED, THE USER IS ADVISED TO ENGAGE IN A DETAILED DISCUSSION WITH OUR COMPANY FOR CUSTOMIZED SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove dust and dirt from all components, and meticulously clean the surface of the insulating porcelain bottle to ensure optimal performance.
2. Meticulously scrub the wiring surface of the ground screw for enhanced connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation and longevity.
4. Inspect the contact surfaces and adjust the compression spring height meticulously so that the contact pressure aligns with the specifications outlined in Table II.
5. This switch is expertly designed for hoisting use and is intended to function seamlessly with the transformer on the line.
6. Offering a rated current between 200-400 ampere hours, this switch typically utilizes three mounting holes. For 600-1000A applications, three mounting holes remain standard.

Conduct an annual inspection of the following switch components:
Diligently clean dirt from conductive parts, contact surfaces, and the insulating porcelain bottles' surfaces to maintain optimal functionality.

Inspect all components for any signs of damage, with particular focus on the integrity of the insulating porcelain bottle to detect potential damage or cracks.

Verify the integrity of the conductive part's contact surface to ensure optimal performance.
