Capacity Available Upto 15 MVA

Power Transformer

Power transformers play an important role in the transmission of electricity from one part of electrical circuit to the other. With an average life-span of 30 years, these serve the best in step-up and step-down of the voltages as necessary.

Servomax is engaged to manufacture and service small and medium power transformers.Weenable greater efficiency and high-quality transformerswithcapacities up to 16 MVA. Our products are subjected to strict and stringent quality controls at every stage of the manufacturing process. We follow specific manufacturing and safety guidelines maintaining the best standards of IS, BIS, ANSI, IEC, DIN, BS, etc. Furthermore, these are tested for quality, efficiency, and safety at Central Power Research Institute labs.
