Meidensha Salient 4 Pole Turbine Generators

Manufacturer: Meidensha Corporation
Model: Salient 4 Pole

Features

We have long years of experiences in turbine generators. We have our solid customer bases at home and abroad. Its prime movers are: steam turbine, gas turbine, furnace top pressure recovery turbine, etc. etc. It offers a stable operation as power supply for continuous, emergency and peak-shaving use for for general industry or power utility.
We realized high efficiency and high reliability by adopting solid casting salient pole rotor.
Due to the brushless design of a permanent magnet generator (PMG), it offers the easy maintenance.
Compact and lighter weight structure to meet the needs for integrated or divided transportation.
It secures the high reliability by adopting an integrated impregnation insulation method.
The adoption of the latest design technology has successfully enhanced its reliability
It offers the sophisticated control by combining the digital AVR (automatic voltage regulator)
