The High Temperature Transformer (TAT, for its Spanish acronym), is a small-sized transformer with efficiency levels higher than those currently existing on the market, which meets the temperature requirements established by the standard.

By including Class 200°C Nomex® solid insulation, and silicon fluids (fire point 300°C) it is an alternative to dry transformers.

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; this transformer features fewer civil work requirements.
These transformers are specially designed to be used in wind power generators, railroad applications and underground facilities.
