Electric heating capacitor (RFM)

Application: Electric heating capacitor is mainly used in controlled or adjustable A. C. voltage system with nominal voltage not more than 4kV and frequency 200 kHz and under, specifically used to improve the power factor or circuit characteristic of equipments for induction heating, melting, mixing, casting, and similar applications. Electric heating capacitor is composed of core and trunk cover, between which is filled with high quality infiltration. The core is welded with cooling water pipes, which are used for cooling capacitor. PP film roughening dipped in high performance liquid is used as composite dielectric and high-purity aluminum foil as battery lead plate. The enclosure is rectangle aluminum alloy fuel tank equipped with water-cooled tube. Main technical characteristics1. The Electric heating capacitor is accordance with GB/T3984.1< Electric heat capacitors for induction heating installations> Part 1: General (equivalent to IEC60110.1).2.
