High Voltage Ceramic Break Insulators

Vacuum insulators (also known as vacuum breaks and isolators) are used to electrically isolate one component or system from another. Nor-Cal uses a ceramic insulator with 95% minimum aluminum oxide content, which is silver brazed to two Kovar sleeves, creating a UHV compatible insulator. The insulator is then welded to the appropriate vacuum flange..

High Voltage Ceramic Break Insulators Features

  • 304 stainless steel flanges
  • Elastomer seal to 200°C
  • Kovar sleeve and ceramic insulator
  • Maximum voltage 3KV015KV depending on size
  • Metal seal to 450°C
Standard vacuum insulators are available in two tube diameters, .75 and 1.5 inches (19.05 and 38.1mm).  The .75 inch (19.05mm) size is rated up to 10KV, while the 1.5 inch (38.1mm) size is offered in two voltage ratings (3KV and 15KV).  All three voltage ratings are available with either two NW (ISO-KF) flanges for high vacuum applications or with one non-rotatable and rotatable CF (Conflat) flange for ultra-high vacuum applications. Other sizes, current ratings and flange combinations are available on request
