Impregnant fluid replaces air pockets in the zinc spray and help in eliminating partial discharges at the end contacts. Oil impregnated capacitors have much higher partial discharge voltage as compared to DR TYPE. JAIVIC impregnated Oil filled Capacitors are hermetically sealed, hence do not have any atmospheric influence compared to DRY TYPE. Capacitor wound elements are encased in metal containers of adequate thickness. The containers are are hermetically sealed. To avoid rusting, metal containers are electroplated which also result in rust free attractive and durable painting.
