Key Performance Features
Engineered for Long Service Life
Advanced Winding Technology
Capacitor elements are wound using modern automatic winding machines in a controlled clean-room environment to ensure consistency and precision.
Robust Element Design
Edge folding and foil folding techniques are applied to reduce partial discharge inception voltage and enhance electrical endurance.
Vacuum Impregnation Process
After drying and heating in PLC-controlled autoclaves, capacitors are vacuum impregnated with highly purified and degassed non-toxic, non-PCB impregnant.
Sealed Metal Enclosure
Dry packs are wrapped in multiple layers of high-quality insulating paper and housed in pre-treated, degreased CRCA containers. Porcelain bushings of required BIL are fitted for leak-proof sealing.
