Our film capacitors use oil impregnation technology which is a homegrown technology and perfected for mass manufacture. Our film capacitors have a lot of advantages over metallized capacitors which have been listed below. 1) Higher dvdt rating, higher peak current capacity, higher insulation resistance over metallized capacitors. 2) Oil impregnation of film capacitors acts as a coolant at higher temperatures and prevents breakdown. 3) Mode of failure in film capacitors is in short circuit mode versus open circuit mode for metallized capacitors
