  • SF6 End-of-life Recycling for Medium and High Voltage (MV

    Nov 17, 2014During the equipment life cycle, use of SF6 helps improve human safety, reliability, and ease of maintenance. However, at end-of-life, governments require strict adherence to equipment disposal regulations. This paper offers guidance on safe, legal methods for MV and HV equipment disposal and recycling.
