Capacitors are made of a Metalised Polypropylene Dielectric Material (MPP). Capacitors deliver reactive current, which helps to improve the system Power Factor.

Types of Capacitors :

Features of the CONZERV Manufactured Capacitors:

  • Self-healing Capacitors.

  • Metalised Double Polypropylene Dielectric.

  • Built-in internal resistors for faster discharge when disconnected.

  • Very low dissipation factor and high insulation resistance.

  • Specially designed bushings having high mechanical strength and better electrical characteristics.

  • Capacitors are hermetically sealed with non- PCB polyurethane.

  • Destruction proof because it has a built-in Pressure Safety Disconnector (PSD)

  • IS marked (manufactured as per latest IS: 13340 specifications).

  • Suitable for floor or wall mounting.

  • Available in Cylindrical as well as Prismatic type.

  • Inductor coil to reduce the effect in-rush current for Capacitors.

Some of the unique features of the Imported MPP-H Cylindrical Capacitor:

  • Advanced Gel construction withstands higher temperatures when compared to dry types.

  • Special composition, metalisation consisting the best properties of Aluminum, Zinc and Silver .

  • 20% lower energy consumption compared to other Capacitors.

  • Compact and economical with upto 50KVAR in a single can.

  • Provides high performance equivalent to Special Heavy Duty, Double Dialectic Capacitor.


CONZERV's Capacitors can be used in all industry segments where the system Power Factor needs to be improved or maintained close to Unity Power Factor (UPF) to avoid PF penalty and avail incentives.

The need for maintaining UPF is heightened in the backdrop of KVAh billing for energy consumption in some states of India .

CONZERV offers the following type of Capacitors depending on the type of load and system voltage:

  • MPP-S (Standard Type ) Power Factor Improvement of steady loads with load variation below 10%.

  • MPP-H (Heavy duty) Double Dielectric : These Capacitors are used to improve the Power Factor where there is a 30-40% of load fluctuation and systems voltage variation is 10-15% of rated voltage.

  • MPP-SH (Special Heavy Duty) Double Dielectric: These Capacitors improve the systems Power Factor where there is dynamic fluctuation of load (0-100%) and system voltage variation, which is 20% and above.
