  • Western Power Distribution - SF6 Alternatives

    As there is a high volume of SF6 11kV RMUs on most DNOs’ networks, the project will focus on these devices and specifically the retrofitting of an alternative interrupting medium to replace SF6. It is recognised that most 11kV primary switchgear does contain SF6 with most being air insulated with vacuum interrupters.

  • An alternative to SF6 in electrical switchgear - EE Publishers

    After many years of research, scientists identified an environmentally friendly alternative to SF 6 that matches all the required properties. The gas mixture is based on a product from 3M called Novec 5110 Dielectric Fluid – a perfluorinated ketone with five carbon atoms (C 5 PFK) (see Fig. 1) [1, 6].

  • Frozen Pipes in Winter Weather - Utilities | seattle.gov

    As you treat the frozen pipe and the frozen area begins to melt, water will begin to flow through the frozen area. Running water through the pipe will help melt more ice in the pipe. Apply heat to the section of pipe using towels soaked in hot water wrapped around the pipe, an electric heating pad wrapped around the pipe, or an electric hair dryer.
