  • 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.

  • Myth About SF6 Gas In Electrical Equipment

    Where is SF6 used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is SF6 a health hazard? Pure SF6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of SF6 used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).

  • Oxygen in Transformer oil - Electric power transmission

    Additionally, O2 occurs as a result of the aging and degradation of paper insulation. If the transformer is of relatively recent manufacture (6-10 yrs.) your oil may contain an O2 inhibitor which in effect "absorbs" oxygen and keeps the numbers relatively low. As the inhibitor saturates the O2 numbers will elevate.
