Why Nitrogen Gas insulation?
While the winding of any single-phase or three-phase capacitor is made with a metallised polypropylene film, there are three different possible types of filling.
Viscous resin/oil and bimetallised paper are the “classic” filling systems for single-phase and three-phase capacitors. The aforementioned filling systems do not guarantee against:
Nitrogen gas (N2) filling, used in our Three-phase Capacitors, has been for the past 20 years been the most reliable, safe and long-lasting technology
Nitrogen gas (N2) capacitors have been tested and approved by renowned ertification bodies and are currently marketed and sold successfully all over the world
It should however be noted that technical competence and know-how are the only key factors to guaranteeing a safe and reliable product.
