Siemens air-cooled generators SGen-100A-4P series are Siemens' solution for turbine generators in industrial plants. They are characterized by high efficiency, low noise emissions, low installation and commissioning costs, high serviceability, and long service life.
The SGen-100A-4P series are four‑pole, three‑phase synchronous air‑cooled generators designed for industrial plants. They offer high efficiency, low noise emissions, low installation and commissioning costs, high serviceability and long service life. Each unit is built with a modular block system that can be customized in diameter, length and optional gearbox.
Technical data include frequencies of 50 Hz and 60 Hz, power factors of 0.80‑0.90, apparent power from 25 MVA up to 70 MVA, efficiencies up to 98.5 % and terminal voltages between 6.3 kV and 15.0 kV. The generators use brushless excitation as standard, with optional static excitation via slip rings, and are available with several air‑cooling methods (TEWAC, CACA, DAC). Reference projects show the series in waste incineration, cogeneration and paper‑mill applications.
