At Red Phase, we maintain the highest levels of customer satisfaction by offering effective customer specific a products at uncompromising quality levels. We offer a widest range of Power & Distribution Transformers that is appreciated all over the world for its strict quality measures and testing standards in all respect.

Our transformers are designed and developed using latest technologies and can be provided with a variety of terminations so as to suit the requirements for new installation or replacement. Optimum efficiency is ensured by delicate proportioning of core and winding losses using CRGO M3 to MS MOH lamination, Electrolyte Grade 99.9% pure copper, with transposition in L.V. coil for current sharing in parallel conductors, electric grade press paper, board and mineral oil. Also, these have cooling systems with on load and off load tap changing facility. Thus better regulation is achieved resulting in higher efficiency and longer life.

The Power & Distribution Transformers offered by Red Phase find extensive usage in multiple sectors like State electricity boards and housing complexes. Our transformers are available in different ratings and voltages according to the requirements of the client.
