dilo MV switchgear SF6-alternative gases units

Oct 15, 2020Current EU F-gas regulation prohibits the use of sf 6 in many non-electric applications, but not in MV switchgear. Today, about two thirds of the 15 million MV switchgear units installed in Europe (EU28) use sf6-gas.When the EU F-gas regulation was last revised in 2014, it was considered that no cost-effective and reliable alternatives to sf6 were available.

  • Technical report on alternative to SF6 gas in MV HV

    GIS (Gas Insulated Switchgear): MV or HV Switchgear in which the electrical insulation is mainly a gas within a gas-tight enclosure. SIS (Solid Insulated Switchgear): MV switchgear in which the electrical insulation is mainly in solid insulating materials. Ambient air or gas may be, however, part of main insulation and/or

  • 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).

  • 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
