Properly engineered and highly reliable transformers are essential to distribute this emerging source of electricity. Whether Wind,Solar, Geothermal, or Biogen, each comes with its own challenges.

Transformers must be able withstand rapid thermo-cycling, inverter harmonics, and extreme environments. Offering circular coils, cruciform core in an engineered core frame and a proprietary cooling design, PCT has all of the tools. You can rely on PCT’s expertise to design and build the right transformer for the application.
