3. Metallization
a. Aluminum : Conventional type metallization with Aluminum layer.
b. Bi layer with Heavy/Reindorced edges (Aluminium/Zinc Alloy) to provide excellent bonding to end spray.
Slope / Taper / Ramp
Linear slope is maintained while metallization by maintaining the resistance value of 2 Ohm per sq. at heavy edge and gradually achieving 20 ohms per sq. towards free margin side.
4. Advantages of Slope/Taper/Ramp
a. Since there is no sudden transition in resistance value between heavy edge to the active area, this feature makes the film electrically stronger & it can sustain more voltage surges as compared to the traditional MPP films.
b. During thr process of winding the surface to surface bonding in case of slop / taper MPP is extremely superior & this quality imparts NO AIRGAP between the dielectrics during winding. This helps in elimination of sparks near the heavy edge.
c. When the voltage is applied to the capacitor the current and heat distribution is absolutely uniform in case of slop / taper MPP Film.

I. Double Dielectric Power Factor Improvement (Shunt) Capacitors
In order to build the correct degree of protection, a capacitor needs to be given a higher current and higher voltage withstanding capacity. This dual consideration has been taken into account to evolve a different construction of capacitors.
Sereis construction is adapted instead of parallel design to achieve the effect of Double Dielectric.
Over and above the normal features of a Mpp capacitor, this desgin provides excellent overcurrent & surge voltage protection.
"Burst proof design in Industrial (Cylindrical with terminal tops) on customers request can also be made available."

Burst proof construction:
Pressure relieving bellows are provided in the case to act as over pressure disconnectors. In case of very high peak voltages this safety bellow activates and disconnects the capacitor elements from the energy sources.
To safeguard from abnormal pressures by internal or external heat and resulting gas formation the bellow expands vertically and breaks the notch allowing safe escape of gas and prevents explosion. The capacitor element is then safely disconnected.
