Technical Specifications and Options:

• Standards: IEC 60076 series, EcoDesign/EU efficiency requirements, IEC 60076-11 (dry type option)
• Power range: 250 kVA – 10 MVA (project-based) (higher powers)
• Voltage levels: 0.69 kV – 35 kV typical; compliance with country-specific MV levels
• Cooling: Hermetically sealed ONAN/ONAF; dry-type (class F/H resin)
• Insulating oil: Mineral, ester (natural/FR3) optional for environmental and product safety
• Connection groups: Dyn11, YNd1, etc. depending on turbine-inverter/topology
• Loss classes: Low load and no-load losses; noise-reduced design
• Terminal/busbar connector: Cable gland, external bushing, plug-in or busbar solutions
• Accessories: Temperature sensors (PT100), oil level/temperature regime, Buchholz, pressure values, fan values
• Protection classes: IP23–IP55 enclosure; salt mist, humidity, and UV-resistant paint/coating
