  • SF6 gas handling - DILO

    Why is the SF 6 quality in the GIS circuit breaker of great importance?. The gas quality is the decisive factor for the correct and reliable function of the switchgear. Moisture or toxic and corrosive decomposition products in circuit breakers might have a negative impact on the insulation properties and switching ca

  • Frequently asked questions on SF6 gas | DILO GmbH, Germany

    What criteria must the SF6 gas meet to be sent to DILO? The gas values for moisture, decomposition products and percentage of SF 6 must be known. The SO 2 value of the gas must be < 250 ppm v. For SO 2 values of ≥ 250 ppm v the customer must carry out partial purification on site before shipping of the gas. DILO can also carry out this purification at the customer’s premises.

  • SF Maintenance Equipment Fundamentals

    publications have surfaced that resolve many questions as to the viability of used gas. As the volumes of SF 6 gas within insulated equipment (GIE) are reduced, a larger proportion of SF 6 inventories are distributed in smaller equipment. And, as larger, older equipment is replaced, many users are finding themselves with excess inventory of “used” SF 6.
