HERMETIC SEALS

Power Feedthroughs


Mainly targeted towards the needs of the AC & refrigeration industry, the Dietze Group’s power feedthrough products serve the high-ampere hermetic or semi-hermetic domain. Usually in the form of feed-through-plates, our glass-to-metal seals are available in single-pin or multi-pin configuration tailored to exact customer needs. Using optional silicone insulators around the bolts the leak-current can be reduced to an absolute minimum level.



Key features:

  • Hermetic high-ampere feedthroughs using glass-to-metal sealing technology
  • Geometry of the feedthrough plates can be up to 30 cm x 20 cm
  • Various surface plating options (e.g. for corrosion resistance)
  • Current carrying capacity up to 300A
  • Working temperature up to 250 °C
  • Optional Silicone encapsulation of bolts
  • Burst pressure of up to 100 bar
  • Low leakage rate up to 10^-9 mbar l s^-1 (Helium leak test)
  • Insulation Voltage up to 5.0 kV
  • Certified according to PED 97/23/EC as well as AD 2000
