sf6 insulated switchgear Network Monitor for Maintenance

Because SF6 has a global warming potential that is almost 24,000 times greater than CO2, it gets a lot of attention. And since the electric power industry is responsible for nearly 80% of the world's usage, our industry has taken significant steps to reduce or eliminate the emissions from gas insulated switchgear.
