Distribution Power Transformers

Servokon is a prominent manufacturer of distribution transformers that are specifically used for converting and distributing electrical energy with high voltage to lower voltages. Basically, high voltage ranges from 11-22-33 KV while low voltage from 250 to 433 V range. However, the frequency remains same before and after the transformer of the electric current.

Backed with a fully furnished manufacturing unit, we are consistently manufacturing high quality power distribution transformer at affordable prices. Maintaining highest standard of quality is our prime goal; that is why the distribution transformers we manufacture are approved by renowned and reputed National Inspecting Agencies like Engineers India Limited (EIL), Department of Industries, Haryana, RITES, CIL, CPWD, SGS, NIT and many other bodies.

Distribution and power transformer manufactured by Servokon have been widely demanded in power supply authorities, suburban areas and other allied industries. Varieties of tests we perform for quality assurance of the product.
