Description

WL–Series Capacitors

NWL’s WL-Series are high energy capacitors used in pulse power and power conditioning applications. With welded metal cases of stainless steel, mild steel, aluminum, or brass, these robust oil-filled capacitors offer the highest energy stored per unit, typically 3-100 kJ. Large diameter, low profile bushings provide minimum inductance for fast discharge and high frequency response compared to Equivalent NWL WF-series capacitors with upright bushings. For maximum peak power, an available option is a 100 kVDC (under oil) bushing with a coaxial current return ring enabling the capacitor to have less than 40 nH of inductance and deliver up to a 250 kA repetitive peak pulse current.

Internal construction is customized for the application and both self-healing and non-self-healing versions are available.

Applications

  • High energy Marx generators
  • Pulsed magnetic field generators
  • EM forming and impact welding
  • Electromagnetic launchers and accelerators
  • EMP simulators
  • Pulsed X-ray generators
  • Lightning simulators
  • High energy physics experiments
