Power-Electronic-Capacitors

 

Applicable:

These Capacitors are for use on dc supplies and are intended to protect the network from momentary voltage spikes and surges and for filtering out ac ripple.

 

Construction:

The self healing, dry type, capacitor elements are produced using specially profiled, wave cut metalized PP film which ensures low  self-inductance, high rupture resistance and high reliability. These elements are enclosed in a cylindrical al case, which is filled with vegetable-oil based, non-toxic, biodegradable, environmentally friendly, solid matter. Overpressure disconnection is not considered necessary. The capacitor top is sealed with self extinguishing PU resin Ul-94 VO. Special design ensures very low self inductance.

Features:

Capacitor life will be shortened by excess temperatures. Capacitors can be mounted in any position. Max torques are mentioned in table below.
