Over 30 Years of Experience

RTE is a consolidated corporation with a clear objetive in mind: to deliver the highest quality and reliability, taking care in every manufacturing detail, presentation and functionality in each one of our transformers.

Distributing energy in Mexico

We manufacture pole type, substation, pad mounted, dry type and submersible electrical transformers from 3000 kVAs, for voltages from 13,200V to 34,500V.

RTE Transformers got started in a car garage manufacturing arc soldering machines. After sometime equipment repair was undertaken and by 1989 manufacturing of distribution electrical transformers got started.

After 30 years of formal operations  we are a consolidated corporation with a clear objetive in mind, to deliver the highest quality and reliability, taking care in every manufacturing detail and presentation in each one  of our transformers.

We have made important efforts to ensure quality, among them in 2001 we installed a testing lab to test all of the production of the equipment and was structured in a way that in 2002 it got it’s acreditation by the Entidad Mexicana de Acreditación (EMA) (Mexican Acreditation Entity). In 2017 CONUEE (National Comission for the Efficient Use of Energy) Evaluated our laboratory certifing it’s  compilance to the current NOM-002-SEDE standard.

We offer functional and robust equipment, manufactured with the best materials and backed up with  a 36  month warranty. Our equipment has the Asociación de Normalización y Certificación (ANCE) certification. In 2015 ANCE granted us with the Excellence Recognition Award, due to our commitment to conformity and in 2018 we were the first corporation to be certified by ANCE for the use of the “Made in México” label.
