Product Introduction
This 12.5 MVA transformer was delivered to the Philippines in 2017. the rated power of the transformer is 12500 KVA. This is step down transformer, the primary voltage of the transformer is 66 KV and secondary is 33 KV. We use copper as winding material. Compared with other metals, copper is characterized by high conductivity, high thermal conductivity and corrosion resistance. Our 12.5 MVA power transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.
SCOTECH ensure each one of our delivered transformers had passed the full acceptance test and we remains 0 fault rate record for more than 10 years so far, our oil immersed power transformer is designed in accordance with IEC, ANSI and other major international standards.
