Transformers - Ujaas Energy Ltd

Through continuous research and development, UJAAS^TM has successfully extended its product range to manufacture transformers upto 25,000 KVA at 132 KV class and includes special duty transformers as follows:

The transformers are manufactured in conformance to Indian Standards Specification IS:2026 and IS:1180, International Specification IEC:76 and / or equivalent. However transformers can be supplied conforming to any other standard if / as specifically required by the customer. We regularly manufacture ratings prevalent in India. However, any other rating can also be supplied on request.

UJAAS^TM is equipped to meet the special requirements of both domestic and foreign markets. Transformers can be designed and manufactured according to our standard specification or customer’s specifications in terms of rating, no load loss, impedance, flux density of core, current density, overall tank dimension or any other technical parameters.

Convertor And Special Purpose Transformers

Converter duty transformers are used as set up transformer from generator to line voltage. Converter duty transformers have range up to 10 MVA with the voltage capacity of up to 33 KV. Converter transformers and heavy duty transformers are very durable and hassle free to be used by desired clients. It comes with an automatic on/off cooling option. We offer these converter duty transformers and heavy duty transformers at a competitive price.

One of the main differences from other types of converter transformers is that the load currents contain higher harmonics due to the distorted waveform. The converter duty transformer causes the distorted current waveform. This current leads to higher losses in temperatures in the transformer. Network regulations also require reduction of harmonic distortion.

The most common use for converter transformers are found in applications such as:

Variable speed drives (VSD)
Aluminium electrolysis
DC arc furnace
Graphitizing furnaces
Traction substations
Copper refining

Power Transformers

We offer power transformer which is known for accepting energy at one voltage and passing it to other voltage. We made power transformer using premium quality materials which are rugged and reliable. The high quality standards adapted by M & B Transformers are appreciated throughout the country. Power transformers upto 25 MVA and 132 KV class are regularly manufactured and supplied to the domestic/international markets as per various standards.
