Power Transformers

    Trafo Power manufactures wide range of power transformers up to 20 MVA with voltage class of 36 kV. These transformers are generally free breathing type. Oil filled in transformer is PCB free Mineral Oil / Midel 7131 / Silicon Oil / Nynas Nytro, etc. as per customer’s requirements.

    Applicable Standards: IEC / ANSI /BS / IS
    These are generally designed and manufactured to comply with below standards. Wide range of transformers in accordance to above standards with different combinations can be Manufactured. These transformers are generally designed and manufactured to comply with the IEC/ANSI/BS/IS/IEC publications 60076/IS 2026 and other standards.

    Power transformers are used in the high voltage transmission network to step up and step down the voltage. These transformers are used as a step up devices for transmission.
