As renewable capacity grows, pumped storage power plants (PSPP) offer the grid-scale energy storage needed to keep power systems reliable. Building new PSPPs in wind- and solar-dense regions significantly improves grid resilience, making high plant availability a key performance advantage.
Choose a generator circuit-breaker built for high electrical and mechanical endurance to lower operating expenses, extend maintenance intervals, and keep lifecycle costs down.
Use a GCB designed to handle frequent daily operations and high-current interruptions, ensuring reliable performance in PSPPs and reducing unplanned outages.
Select a durable, PSPP-optimized GCB that maximizes return on investment by maintaining high availability, lowering service needs and supporting consistent power delivery.
Maintenance-free vacuum technology delivers up to 10,000 CO cycles at full rated current, supported by a sealed vacuum interrupter. A full-spring operating mechanism extends operating life to as many as 20,000 CO cycles.
A complete set of equipment — GCB, PRDS, back-to-back, starting switch and braking — comes from one manufacturer for maximum compatibility and reliability, including one common local control cabinet for all functions.
A compact footprint and reduced space needs make installation easier. Horizontal or vertical configurations and optional disassembled delivery provide flexibility for challenging sites and demanding project conditions.
