TTR Transformers are dry transformers with englobed MV resin windings, which represent a valid alternative to the traditional oil immersed transformers.
Since 1975, SEA has been designing and producing this type of transformers positioning itself as one of the leading firms in the sector thanks to construction solutions adopted, unification of details and to modern technologically advanced production facilities .
SEA TTR transformers have been designed to satisfy our Customers’ needs, from the single user to the large industrial groups, assuring:
Health protection and maximum safety
The materials used are auto-estinguishing and do not release toxic gases in case of fire.
Installation economy
They do not require the construction of oil collection tank
Exercise economy
They minimize maintenance interventions and extend transformer’s life
Versatility and Performances
They can support overloads and perturbations which can be found in every installation
Maximum reliability
Control and quality are guaranteed at every single stage of the design and manufacturing process

The absence of inflammable fluid makes easier plant engineer’s work, who can carry on the project more freely.
This advantage is spefically appreciated for the installations where exercise safety is fundamental, for instance in hospitals, public premises, airports, subway lines, mines, oil platforms, nuclear plants, ships, etc…
