VPI (Vacuum Pressure Impregnated)

ABC Make dry type transformers are manufactured using F (Fiber) or H (NOMEX) class insulation with or without enclosure as per the site / client requirement.Our transformers can help you save space because we design our units so that they work more efficiently and generate less heat. Sturdily constructed using the best quality components, these transformers are also custom made as per the specifications provided by the clients. These are mainly used at Indoor locations or areas which are densely populated.
