Comet's Service Bulletins: your key to the Vacuum Capacitors knowledge.

May 31, 2023

Our Service Bulletins contain a wealth of technical know-how related to our Vacuum Capacitors.

The idea
behind Comet's Service Bulletins

Service Bulletins (SB) contain recommendations and in-depth information related to selecting, testing, installing, operating and maintaining Vacuum Capacitors.

Comet uses Service Bulletins as a format to simplify communication about our Vacuum Capacitors with customers worldwide. The Service Bulletins are published to provide a flow of information between our customers, subsidiaries, representatives, our most important partners, and Comet Plasma Control Technologies.

Increase your Vacuum Capacitors efficiency and productivity by consulting our Service Bulletins.

For any open questions regarding Vacuum Capacitor, customers are trained to consult our online library of Service Bulletins. They provide a general overview but also very specific and easy accessible data about handling, mounting, maintenance, expected lifetimes and other valuable topics related to our Vacuum Capacitors. They are easy-to-read and help with everything from the design phase to the realization of building up a Matching Network. 

Easy-to-understand to help you with specific needs.
