The capacitors are designed for power factor correction and harmonics filtration at medium voltage. They are all-film dielectric - polypropylene foil impregnated with an environmentally friendly, non-toxic biodegradable insulating oil. There is the aluminium foil as the electrodes. This construction assures minimal looses of the capacitors. Three-phase units are in star - Y connection, single-phase units are in I connection. The capacitors have internal discharge resistors.
