Substation / Power Transformers

---

Substation/Power Transformer is the heart of a substation. Our transformer is designed, manufactured and tested to high standards of practice as per specification with quality and reliability. We manufacture both on load & off circuit tap switch transformer for domestic and international customers. This Transformer is generally used for stepping up & down voltage in  transmission network. Transformer tank is suitably designed to allow safe lifting and transportation, effectively sealed for any oil leakage. Transformers are designed & manufactured with due care on health & safety aspects as per respective standards like IEEE, CSA, ANSI, IEC, NEMA.
