Sulfr hexafluoride CIRCUIT BREAKER DEAD TANK TYPE - Mitsubishi Electric

open contacts is insulated only by SF 6 gas: solid insulation that can degrade over time has been eliminated. • Increased interrupting capability: the interrupter is tested and verified to interrupt 90% short line faults. • Less mechanical deterioration:there are no check valves, seals or screens to wear,fail or maintain.

insulating gas valves couplings – Synergy Power Systems

When using the DILO coupling system a leak rate of better than 1 x 10-8 mbar l/sec. is achieved corresponding to less than 1 cm³ in 3 years. The DILO seal principle prevents the loss of insulating gas gas and moisture from penetrating the Sulfr hexafluoride gas system. DILO couplings will eliminate the loss of Sulfr hexafluoride gas by incorrect gas handling.
