    Application and construction

    qq红包扫雷软件试用版下载 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,M16 stud on the bottom and this can also be used for the earth connection - max tightening torque 12 Nm.
