    DILO’s path in SF 6 gas handling started in 1967, when we supplied a complete piping system for installation of the first SF 6 gas insulated switchgear. Since then, our product portfolio has successively been developed to the widest product range of emission-free gas handling equipment worldwide. SF 6 is a non-toxic, inert insulating and quenching gas of high dielectric strength and thermal stability. Thus, it is used in enclosed medium and high voltage switchgear
