Generator switchgear HB1

three-phasemedium-voltagevacuum

Increase power plant reliability and lower costs with the HB1 Generator Switchgear. Its vacuum technology delivers up to 75% OPEX savings and is maintenance-free. Why HB1? The 3-phase enclosed switchgear is compact, comprehensive and benefits from 30 years experience in vacuum technology. It incorporates the HB1-C generator circuit-breaker module as its central component. The HB1 is an advanced generator switchgear designed to protect generators and power transformers. It increases power plant reliability, simplifies operation, and lower costs. It handles currents up to 6,700 A and has a short-circuit rating of up to 72 kA. This system features an air-insulated, metal-enclosed design, integrating a vacuum generator circuit-breaker, main-disconnector, earthing switch, current and voltage transformers, surge arresters, and capacitors. Key benefits Enjoy high reliability The spring-operated mechanism was stated to be the most reliable way to operate a GCB, as per the final report number A3-00 from the CIGRE 2012 General Report SC A3. Reduce long-term costs Cut up to 75% of your OPEX costs thanks to vacuum technology. No maintenance needed for up to 10,000 operating cycles at rated continuous current. Prioritize safety All components and functions are type-tested and routine-tested. Equipped with a sealed-for-life vacuum interrupter.
