4.Real-World Applications
Be used in a wide range of industries.

Industrial Plants
Eliminate power factor penalties in CNC machines and assembly lines while handling surge currents up to 100x rated capacity.

Substation
Stabilizes substation voltage against harmonics and intermittent generation from renewable inverters.

Commercial Buildings
Retrofit aging systems in hospitals or malls with silent (<45dB), flame-retardant capacitors that meet NFPA 70 fire codes.
5.How It Works?
The capacitor’s metallized polypropylene film layers vaporize localized defects during voltage spikes, creating an insulating barrier within milliseconds. This self-recovery mechanism, combined with a pressure-sensitive disconnector, ensures fail-safe operation even during overloads.
