Isolators

Electrical isolators, sometimes referred to as 'breaks' or 'envelopes', consist of metal sleeves brazed to each end of an insulating ceramic tube. These assemblies provide electrical isolation of system components that operate within a common environment. They can also be used to act as a conduit to introduce gases or liquids into hermetic systems.

• Cryogenic isolators are used to introduce cryogenic fluids into a system and to provide electrical isolation of line components.
• Water isolators are used to introduce water or other fluids into a system and to provide electrical isolation of line components.
• Vacuum isolators are used to provide an electrical break between the vacuum system and other external components.
