Power Transformers


    Special features of Power Transformers includes

  • Power Transformers are tailor made to each & every requirement of customers conforming to National & international Standards
  • Transformer is designed by experienced expert engineers using most modern software programmes
  • The process blueprints for each transformer is prepared advanced technologies like AutoCAD & ProE to ensure adherence to the design parameters
  • Highly skilled Transformer Production wing with state-of-the-art manufacturing facilities
  • Transformer losses are minimized by the usage of high quality & high grade CRGO laminations & Copper Conductors like PCC,CTC or Bunched PCC
  • Step lap core with multiple sheets per bag is used in the core lamination jointing
  • Reduced stray loss & transformer noise by means of proper clamping using lean structures
  • Transformer windings are made with new state of the art conductors with high quality paper insulation manufactured under stringent quality norms
  • Transformer oil is directed to the winding to ensure efficient heat dissipation
  • Electrical stress analysis of coil assembly & insulation assembly design is done with advanced software
  • Transformers are designed & manufactured for overloading during service span as per relevant standards
  • Uniform and rigid clamping of the coil is ensured for withstanding forces during short circuits as well as in transportation & service
  • Efficient cooler design to operate under maximum stringent service conditions
  • Specially designed tanks using 3D software and manufactured with best quality steel & modern welding techniques are used to reduce oil volume and to withstand pressure during fault conditions
  • Tank stray losses are much reduced by CRGO & copper Shields
  • High Quality reliable Transformers are manufactured under stringent quality checks at all stages
  • Incoming material quality is ensured by stringent vendor approval procedures
