MPP CAPACITORS:

      The MPP capacitors consists of low loss dielectric formed by pure polypropylene foil. A thin self healing mixture of zinc and aluminium is metallised directly  on one side of the PP - foil under  vacuum. This technology ensures a long operating life of the capacitors. In some cases additional unmetallised foils are added between the metallised ones. The capacitors elements are dried in a vacuum. After insertion into the capacitors case a patented viscous polyurethane resin , mainly containing castor oil or dried insulation gas , is introduced. This protects the winding from environmental influence  and provides an extended life - expectancy and stable capacitance.

Advantages:

  • As result of the comparably simple construction technology, MPP capacitors can be manufactured using less materials and consequently enjoy a competitive price level.

  • Although they have thicker dielectric , MPP capacitors usually have smaller dimensions.

  •  MPP capacitors have a high specific capacitance and high a.c load capacity.
