Use of recycled aluminium: challenges for metal enclosed parts in switchgears

Decarbonizing power systems is a critical global objective, with high-voltage switchgear playing a significant role due to its environmental footprint. As SF₆-free technologies emerge to reduce the climate impact of insulation gases, the focus shifts to the aluminium metal enclosures used in these systems. While SF₆-free switchgear diminishes the gas's contribution to climate change, the increased use of aluminium enhances its overall environmental footprint.
