where can I get so2 evacuation for high-voltage switchgear

Dec 02, 2020 · Either fuses or circuit breakers may be used to protect high-voltage power lines. High-voltage fuses (those used for over 600 volts) are made in several ways. An expulsion-type fuse has an element which will melt and vaporize when it is overloaded, causing the power line connected in series with it to open.
