MPP capacitors are manufactured using high-quality, low-loss metallised polypropylene film and housed in robust cylindrical aluminium enclosures filled with soft, semi-solid, vegetable-oil-based jelly.

The self-healing dielectric technology ensures reliable operation, while the impregnant protects the internal windings and zinc-sprayed contacts against environmental influences, supporting long service life and stable electrical performance.

An integrated overpressure disconnector provides enhanced safety by disconnecting the capacitor from the supply in the event of internal failure.
