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. |
