KEPCO SF6 Equipment Replacement testing

Jul 12, 2018 · During the replacement of expired facilities, waste SF 6 gas is produced. And some facilities are refilled with SF 6 . Since SF 6 is one of the most potent greenhouse gases, KEPCO is developing technologies to recover and separate/refine SF 6 from expired power distribution facilities and reuse it to reduce SF 6 release and maintenance cost.
