Vacuum capacitors are employed in a huge variety of applications that require the generation and management of high power radio frequency power. They’re very dependable, long lasting components. While sturdy, these components can be unforgiving if managed incorrectly.
Vacuum capacitors are really a complex system of individual parts manufactured with tight tolerances. Every one these capacitors, whether ceramic or glass, must be handled with care. If dented in some specific locations, the inner plates that are created out of tolerances as close as 0.010 inches may be emptied out and the device cannot be repaired. But with appropriate maintenance during installation, vacuum capacitors are highly reliable and will have a very long life. High voltage ceramic capacitor should care in the same way.
Some of the things not to do with these units is to knock, shed, or dent them at all. They are generally around and have a inclination to roll off horizontal tables. Vacuum capacitors should be abandoned in the container they have been shipped in, if at all possible, till they are ready to be set up. The units are usually packaged to prevent damage. Do not place capacitors in containers with other capacitors or other areas where they can bang or rub against other substances as they may crack. If the capacitor you’ve is gasoline filled, then removing the protective sleeve may cause injury if dropped, as the contents are under pressure.
