  • SF6 Gas Transformers | Transmission Distribution - Toshiba

    Toshiba GITs are insulated with SF 6 gas rather than traditionally hazardous oil which risks fire, explosions, and contaminating leaks. Additional advantages include reduced footprint and minimal long-term maintenance requirements. Toshiba has installed a base of more than 1400 units since delivering the first GIT in 1967.
