sf6 emissions tanks for 400kv

By following the present international guidelines for use of SF6 in electrical equipment (Mauthe et al., 1997), the contribution of SF6 to global warming can be kept to less than 0.1% over a 100-year horizon. The emission rate from use in electrical equipment has been reduced over the last three years.
