TTR - Cast resin
TTR cast resin transformers are distribution, industrial and power transformers with ratings up to 30 MVA. Medium voltage windings are vacuum casted with epoxy resin and they are suitable for indoor or outdoor applications.
Outdoor solutions can be realized with a wide range of boxes; for lower ratings there is the new type TTR IP00 (without enclosure), validated according to ENEL regulation.
TTR transformer can be used in substations for public buildings, hospitals, airports, and in places where usage of liquid immersed transformers is restricted for fire risk or enviroment protection, e.g. tunnels, marine, cranes, offshore platforms, wind turbines, groundwater catchment areas and food processing plants.
