voltageair-cooledwater-cooled

Overview
Comprehensive range of low- and high-voltage electric motors (400 V to 15 kV) from 37 kW to 35,000 kW and synchronous generators up to 15 kV and 65,000 kVA (65 MVA). ELIN Motoren supplies non-safety-classified and safety-classified machines in tailored configurations. Equipment can be qualified for accident conditions (LOCA, ANLE), seismic events, and degraded ambient conditions including radiation exposure, by calculation and/or testing to meet regulatory and reactor-specific requirements.
