SF6 End-of-life Recycling for Medium and High Voltage (MV & HV) Equipment
Sulphur Hexafluoride (SF6) is a greenhouse gas that is widely used as an insulator and breaker medium within switches, circuit-breakers, and other MV and HV electrical transmission and distribution equipment. During 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.
