Special Type Transformers are designed and manufactured for special areas of use in line with the customer demand and international standard powers and voltages. It operates under extreme currents and reactive loads under special operating conditions for special purposes. Due to the special working conditions required on this kind of transformers, their designs are handled specially and are considered as the highest point of the transformer sector due to the knowledge required by design and production technology, workmanship experience, care and sensitivity. Roza Transformers can produce this transformer up to 7.5MVA as power and high voltage up to 36kv, three phase or single phase, Oil expansion tank or hermetically sealed, 50Hz or 60 Hz Frequency, ONAN, ONAF or Customized Cooling Type, Yzn, Dyn or Customized Vector Group, with Off-Load or On-Load Tap Changer, used both external and internal, IS, IEC, ANSI, JIS, DIN, BS Etc…as applicable standards and Geographical Conditions: Concerned country’s conditions (Altitude, Humidity, Temperature values etc.).

The main fields of use for such transformers include; Solar Power, Wind Power, Railway Systems, Mining Operations, Cruise Ships, Pump Stations, Paper Mills, Nuclear Power Stations, Oil Refineries, Crane Applications; and, all industrial facilities requiring DC systems that why these transformers; should be durable due to heavy duty operating conditions, should be designed with special technical solutions since harmonic frequencies increase thermal, mechanical and dielectric stresses, must have multiple secondary coils based on differing phase angles, must have reactive durability, must have low malfunction rate; and, provide consistent operation.
