Product Description

Product Description

Introducing the (H)GWBEB type, an outdoor high-voltage isolation disconnect switch meticulously engineered to enhance your power transmission and distribution infrastructure. Ideal for operation on 10(12, 15, 24)kV high voltage lines, it effortlessly manages the opening and closing of single-phase or three-phase circuits without experiencing load fluctuations, while voltage remains steady. This innovative product is a staple for efficient, safe, and reliable power management.

Tailored for single-phase use within three-phase systems, this switch shines with its straightforward design, affordability, and user-friendly nature. With multiple rated currents to choose from, including 200, 400, 600, 800, 1000, and 1250 amps, it caters to various needs. Its construction features a sturdy base, robust post insulators, conductive components, and a sophisticated mechanical section. The gate knife structure, a hallmark of its design, ensures precise circuit control, with each phase incorporating dual conductive blades and external compression springs to maintain optimal contact pressure. Operating this switch is seamless with an insulated hook stick, further enhanced by a self-locking mechanism to uphold safety and reliability.

Working Environment:

Designed to perform optimally at altitudes not exceeding 1000 meters;

Engineered for environments with ambient temperatures peaking at +40°C and dipping no lower than -30°C;

Resilient to outdoor wind speeds up to 35 meters per second;

Capable of withstanding seismic intensities up to 8 degrees, provided the installation site remains free from frequent severe vibrations.

Ensure the installation site is devoid of gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive mediums that could compromise the switch’s insulation and conductivity.

Note:

WHEN STANDARD OPERATING CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS ALTERNATIVE SOLUTIONS WITH OUR COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Perform a thorough cleaning to remove dust and impurities from all components, meticulously wiping the insulating porcelain bottle surfaces for optimal performance.
2. Meticulously clean the wiring surface of the ground screw to ensure reliable connectivity.
3. Apply a protective layer of industrial Vaseline to rotating parts and contact areas to enhance durability and performance.
4. Inspect the contact surfaces; adjust the compression spring height to assure the contact pressure aligns perfectly with Table II specifications.
5. This switch is designed exclusively for hoisting applications and should be used in synergy with the transformer on the line for optimal efficiency.
6. For rated currents of 200-400 ampere hours, generally, three mounting holes are utilized, while for 600-1000A, the same applies to ensure secure installation.

Annual Maintenance Checklist:
Regularly cleanse dirt and grime from conductive parts, contact surfaces, and insulating porcelain bottle surfaces to maintain optimum performance.

Conduct thorough inspections for any damage, with particular attention to the insulating porcelain bottle, checking meticulously for damage or cracks.

Assess the quality of the conductive parts' contact surfaces to ensure they remain in pristine condition.
