  • SF6 Gas-Insulated Transformer | Transformer | MEIDENSHA

    SF6 gas known for its non-flammabilit and coordinative ability with environmental conditions. Lt was widely used in underground substations and inddor substations at underground shopping areas, traffic systems, and public structures. SF6 Gas-Insulated transfomers are designed to reduce fire hazards and less risk on the environment. By directly coupling with gas-insulated Switchgear, substation space can be minimized as the result of compact facilities.
