Vacuum Solutions and Systems for Power Capacitor Production from Leybold
High-performance power capacitors demand pristine oil quality, moisture-free insulation, and precise vacuum processes. Leybold, a global leader in vacuum technology, delivers complete solutions for every production stage—from impregnation to final degassing.
Why Vacuum Is Crucial in Capacitor Manufacturing
Vacuum enables deep oil impregnation, removes trapped air and moisture, and ensures hermetic integrity—enhancing dielectric strength and reliability.
Key Vacuum Processes
1. Vacuum Impregnation & Drying
Working pressure down to 0.1 mbar allows air evacuation and full resin/oil penetration. Subsequent drying under 0.01 mbar removes remaining moisture and volatiles.
2. Oil Degassing
Leybold systems extract dissolved gases from materials and oil, preventing partial discharges and ensuring stable insulation performance.
3. Leak-Tight Vacuum Chambers
High-integrity chambers with rotary and booster pumps maintain low leakage rates (as low as 10 Pa·L/s), enabling consistent vacuum during cycles.
Vacuum Equipment from Leybold
SOGEVAC / TRIVAC — oil-sealed pumps for drying and impregnation
RUVAC — Roots boosters for faster pump-down
DRYVAC / VARODRY / LEYVAC — dry, oil-free vacuum pumps
COOLVAC — cryopumps for ultra-high vacuum (to 10⁻¹¹ mbar)
