QUALITY

We are ISO 9001:2008 and ISO 14001:2004 certified and we continuously invest in our internal quality control system. Our products are designed, manufactured and tested according IEC and IEEE/ANSI standards.

Specialtrasfo’s rigorous quality control policy covers every design and production stage, from the inspection of incoming materials and the checking of individual components to final performance testing and after-sales service.

The company’s goal is to provide its customers with the best quality products and services available on the market through continuous development of the individual skills of our human resources, improvement of design engineering and technology of our products and continuous investments in all our three production facilities.

Besides, when requested our transformers are subject to strict external control by independent certification bodies and are compliant to:

In Specialtrasfo quality goes beyond certifications programs, it is the way to obtain state-of-the-art reliability and conduct business successfully. And success for us consists in our customers’ satisfaction.




QUALITY CONTROL AND AFTER SALES

Specialtrasfo invests significant resources in its quality control process and its continuous improvement.
Specialtrasfo can mobilize its service engineering team within 24 hours anywhere in the world directly from its headquarters in Italy and/or through selected service partners.

In North America we have selected service partners which can quickly intervene in case of standard maintenance, diagnostics and all activities which involve action on accessible transformer components and fittings
(i. e.: cooling system, piping and gaskets, oil-treatment, marhalling box and auxiliary cables, accessories, protection relays, other ancillaries, painting, etc.). All these activities are conducted under strict supervision of our service engineers and technical department in Italy.

Our partners will also provide their local facilities and crews to assist our service engineering team which would be dispatched to site in the unlikely event of the need to un-tank the transformer active part.

We guarantee that our transformer most delicate and important parts (its core&coils) would be in any case inspected, re-engineered and repaired only by Specilatrasfo’s engineers.
