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.
