Vacuum pressure impregnated transformer

There are primarily two main manufacturing techniques for dry type transformers; Cast Resin and Vacuum Pressure Impregnated (VPI) with their own typical features. The main difference is their insulation class; Cast Resin is Class F (155°C) and VPI is Class H (180°C). The Vacuum Pressure Impregnated transformers not only offers in-build safety feature but there are many other advantages of using these transformers such as improved reliability, reduced losses, minimal maintenance, enhanced overloading capability etc.

PEL's Initiative for Technology Transfer
Considering these advantages of dry type transformers, Pak Elektron Limited (PEL) took the initiative and went into a Technology Transfer Agreement in March 2007 with DuPont Pakistan Limited (DPOL) for Designing and Manufacturing of Vacuum Pressure Impregnated dry transformers with Nomex® paper. PEL is now pleased to announce that PEL will be the first local company in the production of dry type transformers in Pakistan.
