How is SF6 medium-voltage electrical equipment recycled.
The equipment is first collected from the customer's site and delivered to a Schneider Electric Centre where it is dismantled. The various ferrous metals (scrap iron, sheet metal, etc.) and non-ferrous metals (copper, aluminium, etc.) are separated and sent to appropriate recycling centres.
The enclosure containing the SF6 gas is evacuated at up to a residual pressure of less than 20 mbar in conformance with the IEC 62271-4 standard, using special equipment. The gas is bottled before being sent to a gas specialist.
If the equipment has an epoxy enclosure, this is crushed for recovery purposes.
