Crompton Greaves develops 800 kV transformer

Mumbai, Oct 3 (UNI) Crompton Greaves Ltd (CG), an Indian multinational with manufacturing bases in 8 countries, has become the first company to indigenously manufacture 800 kV class power transformer.

The company developed it on behalf of National Thermal Power Corporation (NTPC) for its Sipat STTP Project Stage-1 at Chhattisgarh.

The high power transformer was manufactured by the company in a technical collaboration with Japanese company Toshiba at its manufacturing plant at Mandideep in Madhya Pradesh.

''With this achievment, the company has entered in the domain of a very few global companies having such capability,'' the company said here today in a release.

Commenting on the development, CG's Managing Director Sudhir M Trehan said ''As India's transmission system converts from the existing 400 kV levels to global standards of efficient Extra High Voltage 765 kV systems with improved power quality and grid reliability, Crompton shall be at the forefront to usher in the change.'' According to the company sources, presently an 800 kV power transformer is the highest grade system voltage for transmission worldwide and results in fewer transmission and distribution (T&D) losses in addition to lesser maintenance and other overheads. The per unit power cost thus goes down substantially in such transformers.

The company has an installed base of 120 million kVA in transformers and boasts of the world's largest fully-shielded Ultra High Voltage (UHV) laboratory attached to a power transformer manufacturing unit, the release added.
