  • FAQs - DILO

    What are Alternative Gases used for? By using SF 6 gas, switchgear can be made much more compact and material-saving, combined with a higher switching capacity and plant safety. Due to the very low GWP value and similar properties to SF 6, these gases are well suited for use in medium and high voltage switchgear.

  • What are the alternatives to SF6 gas? - ECA Today

    Mar 31, 2020Again, minimal maintenance requirements help to achieve low lifecycle costs, compared to current SF 6 switchgear. High voltage challenges. Finding suitable alternatives to SF 6 for high voltage operations is, however, more challenging and even when they are available, alternative technology to using SF 6 still tends to be more expensive overall.

  • An alternative to SF6 in electrical switchgear - EE Publishers

    For decades, the unique properties of sulfur hexafluoride (SF6) have made it popular as an insulation and switching medium for electrical switchgear. SF6 is a greenhouse gas and there are life-cycle management costs associated with its use. For some years, ABB has been conducting research into alternatives with lower environmental impact but with insulation […]

  • Gasket design for SF6 leakage - Switchgear Content

    Apr 13, 2019Leaks occur because the gaskets used in the equipment begin to leak as the gasket material deteriorates with age and use. 3 factors are important in gasket design: Hardening of the gaskets. High ambient temperatures and heat produced by the current passing through the circuit breaker in normal use affect the gaskets’ elasticity and harden

    SF 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.

  • Green Switching: A sustainable alternative for SF6 gas

    Aug 23, 2010But, while there is no economically viable alternative to SF6 gas for high voltage (HV) switchgear ( 52 kV) in the transmission network, application of SF6 is totally unnecessary for medium voltage (MV) switchgear (< 52 kV) in the distribution network. Fully equivalent alternatives are commercially available on the market (2).
