Power Transformer

Substation / Power Transformer

The substation / power transformer is a critical component of a substation. Our transformer is designed, manufactured, and tested to meet applicable specifications and industry standards, with quality and reliability. We manufacture both on-load & off-circuit tap switch transformers. This transformer is generally used for stepping up and stepping down voltage in the transmission network. The 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 in accordance with applicable standards, including IEEE, CSA, ANSI, IEC, and NEMA.
