Permanent innovation is the base for adapting us to new market demands and for continuing to be a leading company in our field.  In this context we are continuously improving our product range and developing new products that offer new solutions to our customers.

 The more and more important issue of harmonic problems in the electrical networks has inspired us to develop a unique range of harmonic filters named ‘Compensators’. The Compensator harmonic filters are based on a new concept and offer several advantages with respect to other filters in the market.

We have developed a new range of control transformers with very innovating features, unique characteristics and a very attractive design. The ‘P’ transformer ‘The ultimate transformer design’ has been developed to meet today’s market demands.

Many innovation projects have been carried out and many more are yet to come as we will continue to introduce new products and solutions in the future.
