Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also known as an isolation disconnect switch, is an engineering marvel specifically crafted for use on 10(12, 15, 24)kV high voltage power transmission and distribution lines. This switch is able to seamlessly open and close single-phase or three-phase circuits under voltage conditions, providing a reliable solution without load.

Tailored for single-phase use within three-phase line systems, this switch boasts a remarkably simple structure, making it both cost-effective and user-friendly. With available rated currents of 200, 400, 600, 800, 1000, and 1250 amps, these switches comprise a robust base, durable post insulators, conductive parts, and an efficient mechanical section. The innovative gate knife structure ensures precise opening and closing of the circuit, utilizing two conductive blades per phase with external compression springs on both sides. Fine-tuning of the spring height ensures optimal contact pressure. The switch's operation is facilitated using an insulated hook stick, ensuring smooth opening and closing actions, complemented by a self-locking mechanism for enhanced safety.

Working Environment:

Installation perfection is achieved at altitudes not exceeding 1000 meters;

The ambient temperature range is meticulously controlled: maximum not above +40°C and minimum not below -30°C;

Stability is ensured with outdoor wind speeds not exceeding 35 meters/second;

The switch is designed to withstand seismic intensity up to 8 degrees, ensuring that the installation site remains free from frequent severe vibrations.

The installation site should remain pristine, devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that could adversely impact the switch's insulation and conductivity.

Note:

SHOULD THE ABOVE-MENTIONED NORMAL USE CONDITIONS BE EXCEEDED, USERS ARE ENCOURAGED TO CONSULT WITH THE COMPANY FOR TAILORED SOLUTIONS.

Installation, Use and Adjustment

Pre-installation work

1. Ensure a flawless start by removing dust and grime from all parts, and meticulously wiping the surface of the insulating porcelain bottle to perfection.
2. Assure excellent conductivity by scrubbing the wiring surface of the ground screw.
3. Protect the moving parts with a gentle layer of industrial Vaseline on the rotating components and contact areas.
4. Verify the contact surface and adjust the compression spring's height with precision, ensuring contact pressure is in strict adherence to Table II.
5. Engineered for hoisting applications, this switch is exclusively compatible with transformers on the line, offering seamless integration.
6. Configured for rated currents between 200-400 ampere hours, typically utilizing three mounting holes. The 600-1000A configuration similarly employs three mounting holes for steadfast installation.

Commit to excellence by conducting an annual inspection of the following switch components:
Meticulously clean the conductive parts, contact surfaces, and the insulating porcelain bottle surfaces to maintain peak performance.

Thoroughly inspect all components for any signs of damage, with special attention to the insulating porcelain bottle for cracks or breakage.

Ensure the conductive part contact surfaces are in impeccable condition for optimal functionality.
