oem SF6 room LeakSpy for transformers

Toshiba's Gas Insulated Transformer (GIT) is the most technologically advanced solution for hydro-power and underground substations, densely populated cities, mission critical substations, and offshore substations. Toshiba GITs are insulated with SF 6 gas rather than traditionally hazardous oil which risks fire, explosions, and contaminating leaks.
