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.
