Marsons manufactures power and distribution transformers ranging from 10 KVA to 100 MVA 132 KV class, furnace transformers, dry type transformers and various types of special application transformers. The company’s transformers of various rating have been successfully type-tested at CPRI in Bhopal and Bangalore.
In 1994, the company came out with a public issue to part finance the expansion of its facilities to manufacture power transformers up to 66 kV and 132 kV class, upto 20 MVA rating.
Marson’S constantly updates its products with the latest development and innovations in the industry. The company’s plant is located in Kolkata, spread over an area of 35,000 square feet with a built-up area of approximately 18,000 square meter. The plant is fully equipped to manufacture power transformers of up to 100 MVA 132 KV class. It recently upgraded the facilities to manufacture EHV power transformers up to 160 MVA 220 KV Class.
Marsons is among the first to set up Impulse Testing Laboratory and Autoclave (Vacuum Heating System) way back in 1995-96. The laboratory is equipped with 1600KV 80 KJ impulse generator imported from Haefely Trench of Switzerland. Its laboratory is also fully equipped to perform all required routine tests and temperature rise test for various ratings of power transformers up to the range of 160 MVA 220 KV class.
The testing departments with its hi-end equipment play a decisive role in the implementation of quality. It has two laboratories, both equipped with modern machineries and precision instruments; tests are conducted separately with one laboratory being alloted for high/ medium voltage transformers and the other one for medium/ low voltage transformers.
