Super Heavy Duty Capacitors are designed and developed to meet reactive power requirements of modern day industries having higher harmonics. These metalized polypropylene capacitors ranges from 1.2-33.3 kVAr with cylindrical type construction. They can withstand peak inrush current of 350 times the rated and an overload withstand capacity of 2.5 times rated current. They have better harmonic withstand capability and long life along with necessary safety features like over pressure disconnector and self-healing technology.
