Induction heating furnace capacitor, 3000kvar
Application:
Electric heating capacitor provide solutions in a wide variety of induction heating applications, from forging to melting, heat treating and annealing, to billet heating and hardening, also for tune special furnace circuits.
The capacitor is designed and manufactured in according with the latest revision to IEC 60110-1.
They are constructed from the Polypropylene and/or Paper with Foil. The impregnate is non-PCB ( non-polluting and non-toxic) Dielectric oil. External case is generally aluminium.
After wingding the exrended foil capacitor elements, one edge or both edges are soldered to tinned copper tube, through which water is passed to dissipate the heat generated in the capacitor.
The non magnetic container is used to assure minimum heat generation when operating at high frequencies, the insulation ceramics terminal bushings which comprise one pole are hermetically fixed to the capacitor container and equipped with a heavy copper stud having a suitable current carrying capacity for the rating. The other pole of all sections is common to the cooling coil.
Specially developed techniques are employed to ensure high electrical connectivity, thermal conductivity and mechanical strength between the foil and copper tube.
