Tubos Trans Electric launches the High Temperature Transformer (TAT, for its Spanish acronym), thus becoming the first regional manufacturer of this type of transformers.

Year after year, the world's needs tend to value losses in an ever more demanding manner and to have greater space limitations. The available space at existing facilities and the weight limitations at special facilities call for the development of even smaller transformers. In response to these needs and based on IEC 60076-14 standard - Design and application of liquid-immersed power transformers using high-temperature insulation materials - of 2004 and its latest revision (2009), TTE has developed a High Temperature Transformer (TAT), a small-sized transformer with efficiency levels higher than those currently existing on the market which meets the temperature requirements established by the standard.

The project, jointly undertaken with DuPont, included the development of the calculation and fabrication methods, and the selection of unconventional materials. The result was a 1000 kVA transformer, with a 13.2/0.4 kV transformer ratio, 5% impedance, Class 200° C Nomex® solid insulation, and silicone fluids (fire point: 300° C), which can have a volumetric saving of 75% and reduce no-load losses up to 30% as compared with transformers under IRAM 2250 standard. The transformer has been duly and satisfactorily tested at the High Voltage Lab of the National University of Córdoba (UNC).

Thus, TTE has launched the TAT: An alternative to dry type transformers which, in addition to having a smaller total size and generating lower losses - something that given the increase in energy costs will turn it into an ever more economical option -, features fewer civil work requirements.

As a result of its commitment with permanent technological innovation, TTE has become the first regional manufacturer of this type of transformers successfully used for wind power generation, railroad applications and underground facilities, thus paving the way for new business opportunities for both the company and its suppliers.
