(H)GWBEB type outdoor high-voltage isolation switch is a pinnacle of engineering, specifically tailored for 10(12, 15, 24)kV power transmission. This isolation disconnect switch excels at safely opening and closing circuits in high voltage environments, maintaining voltage presence without load. Its robust design assures reliability for both single-phase and three-phase applications.
Designed for simplicity and efficiency, this switch is optimized for single-phase usage within three-phase systems. Offering an impressive range of rated currents from 200 to 1250 amps, it combines cost-efficiency with user-friendly operation. The switch comprises essential components: a sturdy base, durable post insulators, conductive elements, and a refined mechanical section. The innovative gate knife structure ensures precise circuit control, featuring dual conductive blades enhanced by external compression springs for optimal pressure. An insulated hook stick guarantees safe operation, complemented by a secure self-locking mechanism.
Working Environment: Tailored for diverse installation contexts, ensuring adaptability and resilience.
Altitude not exceeding 1000 meters: Engineered to perform flawlessly even in elevated terrains.
Ambient temperature: Reliably operates in a broad range from a maximum of +40°C to a minimum of -30°C.
Outdoor wind speed not exceeding 35 meters/second: Built to withstand challenging wind conditions.
Seismic intensity not exceeding 8 degrees: Designed to endure seismic activity, ensuring stability.
The installation site should be free from harmful gases, chemical deposits, salt mist, dust, and dirt. Guaranteeing the switch's peak insulation and conductivity, free from explosive or corrosive elements.
Note: Important considerations for exceptional cases.
WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN NEGOTIATE WITH THE COMPANY: Flexible solutions for unique circumstances.
Installation, Use and Adjustment: Step-by-step guidance for effective deployment and maintenance.
Pre-installation work: Essential preparations for optimal performance.
Regularly perform annual inspections on the following switch components to maintain peak performance.
Remove accumulated dirt from conductive parts, contact surfaces, and insulating porcelain bottles to preserve operational integrity.
Inspect all parts for signs of damage, with particular attention to the insulating porcelain bottle for any cracks or imperfections.
Verify the integrity of the conductive part's contact surface to ensure uninterrupted functionality.
