Application and construction

Capacitors are intended for the improvement of Power Factor in low voltage power networks. Used MKP technology consists of metallized PP film with extremely low loss factor. The dielectric system is self-healing and has no liquid impregnant.

Capacitor elements enclosed in cylindrical aluminium cases are filled with a vegetable oil based gel which is non-toxic, biodegradable and environmentally friendly.

The capacitors have overpressure protection to disconnect it from the supply in the event of internal failure and at the end of its operational life.

The construction described above and the use of high quality materials ensure reliability and longevity.

Installation instructions

Capacitors can be installed in any position. Mounting is by M12 stud on the bottom and this can also be used for the earth connection - max tightening torque 5 Nm. Connection in terminal is done by M5 screws - max torque 2 Nm. Connecting cables must permit the capacitor top to rise by 20 mm to ensure correct operation of the overpressure disconnector. Expansion upper part of the capacitor must be free without any fixing clamp. If necessary, fixing clamps can be mounted on the lower capacitor part below the groove only.

Back up fuses should have gG characteristics and they should be rated at twice the nominal current of the capacitor(s).
