常见问题

What is the primary function of a feedthrough insulator/seal?

To simultaneously provide electrical insulation and environmental sealing where conductors or mechanical elements pass through equipment barriers.

How do temperature variations affect insulator/seal performance?

Temperature changes cause material expansion/contraction, potentially compromising seal integrity and dielectric properties if not properly designed with compatible CTE materials.
