The one-minute in-flight operation on a live wire -- a stunning feat previously reigned by the US, Canada, Australia and Israel -- marks a quantum leap in China's electric power overhaul technology. The live-wire maintenance, to ensure uninterrupted power transmission, helps save electricity worth 2.5 million yuan per hour, Xinhua reported.
