SF6 gas Mixtures Electrical Equipment plant

If the equipment is filled with SF 6 gas mixtures, such as SF 6 /N 2 or SF 6 /CF 4, both instruments can be configured by the customer. The continuous monitoring of SF 6 from the control room gives the foundation for condition-based, and thus cost-optimised, equipment maintenance.

    Ideally the gas mixtures should be suitable for use in the existing equipment as well as in the equipment that will be designed and manufactured in future. Extensive research work done in SF 6 and its mixtures with N 2 , air and CO 2 has given breakdown values which are 80-90% of the pure SF 6 values as shown in Table 2.1.

  • SF6 GAS - DILO

    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 as an arc quenching and insulating gas due to its properties. Unfortunately, the same properties that make SF 6 an excellent insulating gas for GIE also make it a potent greenhouse gas.
