sf6 Evacuation device for Substation

"This gas, known primarily for its insulation properties in utility substation circuit breakers, can leak at mechanical fittings and couplings. If too much SF6 gas leaks, a catastrophic failure of the breaker can occur, costing over $100,000 to repair and resulting in localized outages," said Marc Makely, president of Premier.
