Oil Capacitors

Standard – IEC 831-1/2

“As capacitors are the major component of a Power Factor Correction System, many hours of testing and evaluation have been invested in their selection and physical mounting within the cubicle.”

Our capacitors are of the highest quality German Manufacture with mineral oil or dry or gel impregnated types available, all in cylindrical Aluminum cans complete with overpressure disconnection device and discharge resistors (to meet AS3000). Capacitors are self-healing polypropylene film with maximum 65°C case temperature rating. Rated current is 1.5 times maximum in the presence of 10% Over voltage and Harmonics. Power Loss is <0.25 Watts per kVAr
