ALL POLYPROPYLENE FILM FOIL, LOW LOSS Capacitors are manufactured by using Hazy polypropylene film, which is placed between two layers of metal foil and windings.
For use in Improvements of Power Factor of System consisting of Inductive Loads.
Specially recommended in critical applications when loads impose arduous service condition.
Such load consists of :
- Large D.C. drives / Inverters.
- Fluctuating loads such as Steel Rolling Mills.
- Inching loads such as Lifts; Cranes; Variable Speed Motors.
- Heavy duty Spot Welding Machine operation.
- Induction Furnaces.
- Arc Furnaces (To be used along with Series Reactors).
"Capco" brand All PP-Aluminium Foil Power Capacitors are manufactured in
controlled atmosphere using modern machinery & latest manufacturing techniques.

Design Features
- Hazy Polypropylene film used so as to achieve best impregnation.
- Very low losses in the Capacitor unit. As such no internal hot spot.
- With Oil impregnation, better cooling as such temperature rise of Capacitor is low in turn
enhancing life of Capacitor.
- Provision of internal element fuses.
- Non Toxic Ecofriendly impregnants used.
- High Voltage & Current Surges handling capacity.
- Rugged Mild Steel containers externally painted with Synthetic Enamel paint.
Benefits of Non-Self Healing Capacitors:
- Operates at very low current density
- Can comfortably withstand heavy inrush currents
- Withstand high current variations as in the case of Arc Welding equipments and other such loads of a fluctuating type
- Withstands heavy and varying currents associated with parallel switching such as those occurring in automatic power factor correction
- Operates at low dielectric stress
- Withstands frequent and high voltage fluctuations prevalent in the industrial segment power supply system
- Sustains over voltages occurring due to the presence of harmonics to a reasonable level
