Vacuum interrupter - Wikipedia

After the 1970s, vacuum switches began to replace the minimal-oil switches in medium-voltage switchgear. in the early 1980s, sf6 gas switches and breakers were also gradually replaced by vacuum technology in medium-voltage application. As of 2018, a vacuum circuit breaker had reached 145 kV and breaking current had reached 200 kA.
