  • Vacuum interrupter - Wikipedia

    In 1966, devices were developed with a rated voltage of 15 kV and short-circuit breaking currents of 25 and 31.5 kA. After the 1970s, vacuum switches began to replace the minimal-oil switches in medium-voltage switchgear. in the early 1980s, SF6 switches and breakers were also gradually replaced by vacuum technology in medium-voltage application.
