First Supercritical CO2 Circuit Breaker Debuts

Cars That Think

Such equipment is scattered widely throughout power grids as a way to stop the flow of electrical current in an emergency. Hundreds of thousands of circuit breakers dot power grids globally, and nearly all of the high voltage ones are insulated with SF 6. locationa gold standard certification facility.
