知識コラム

問

This article introduces the principle of capacitors with insulating media and their role in practical applications. Explored different types of insulated dielectric capacitors and their characteristics, and demonstrated their excellent performance through practical cases.

問

There are usually multiple options for the insulation medium of high-voltage standard capacitors. Common ones include oil paper insulation, polyimide film, etc. Oil paper insulation is a relatively traditional type, which is composed of insulation paper and insulation oil. Insulation paper has high mechanical strength and insulation performance, and can withstand the action of electric fields to a certain extent without being broken down. Insulation oil can be filled in the gaps of insulation paper to enhance its strength
