Medium voltage power capacitors

For more details please open our catalogue: Power factor correction.pdf

Application

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.

Installation instruction

Impregnant is free from PCB and is completely non-toxic. It is very stable over a wide operating temperature range
All three-phase and single-phase units are in dead case
Single-phase units are available with two bushings or connected with a single bushing and live case
Low voltage pressure sensor 230 V, 50 Hz available
Terminal cover IP42 available
Stainless steel case, paint finish. For indoor/outdoor installation
Max torque – hollow studs M12 - 10 Nm
Max torque - earth connection M10 - 7 Nm
