High Voltage Power Capacitors
Features of High Voltage Capacitors
  1. Internal fuse types or standard type (fuseless) available upon request.
  2. Low dissipation factor, low-temperature rise, long service life.
  3. Stable capacitance with little variation due to temperature.
  4. Impregnated with high insulation strength and non-PCB biodegradable fluid in the vacuum tank.
  5. Internal fuse capacitor mainly has more safety, higher reliability, less installation space, lower installation, and maintenance costs.
