Brief Instructions of Ceramic Vacuum Switches Ceramic vacuum switches use vacuum as dielectric with ceramic envelope, which have the following features:
- high operating volzage - high carrying current - small size - high capability of arc-extinguishing
- lower electric abrasion - long life - easier installation and maintenance
The vacuum tubes are widely used in power, metallurgists, mine and other electricity transmitting systems, as controlling and protecting components, especially for the site of high frequency operation.
