Film capacitor PTR series

cylindricalthree-phase

CONSTRUCTION TECHNOLOGY The self-healing capacitors in the PRT series consist of three single-phase elements made of metallized polypropylene film at high gradient with a delta connection and in a cylindrical casing of extruded aluminium, with a fixing spigot M12 x 12 mm used to earth the capacitor. The capacitor is closed with the beading of the steel disc on the aluminium casing, ensuring perfect air and water tightness. The fiberglass-reinforced nylon strip is dielectrically assembled on the steel disc with an airtight fit. The strip accommodates the three terminals. PRT capacitor series can also be realized in a dry version. Dry capacitors are not standard stock items but production is on request. In case of request the purchase order code must be completed with the letter “D” before product code. If lower discharge times are required, it is necessary to use fast discharge resistors (supplied on request) that enable the capacitor to discharge in just a few seconds.
