Features. Large variety of electrical feedthroughs with wide range of electrical ratings to cover most requirements. Voltage ratings are conservative DC flashover with clean ceramics. Special feedthroughs can be constructed for your application.

Electrical Feedthroughs.

Electrical feedthroughs are used to transfer electrical power through the vacuum system wall. There are many different types of feedthrough but they can be roughly divided into two categories,Power & Instrumentation.Power feedthroughs are used to carry either high current, or high voltage, or both. Instrumentation feedthroughs are used to carry electrical signals (including thermocouples) which are normally low in current & voltage.

Important

Adequate safety precautions must always be taken by the user when feedthroughs are operated at high voltages or currents. Remember that many of the external ends of the feedthroughs can be exposed. Please note that the ceramics can absorb moisture under certain atmospheric conditions which may reduce stated breakdown voltages, this may be improved by bakeout.
Electrical ratings specified apply in clean vacuum or dry atmospheric conditions.
