What are the developments in the power automation industry?
Since the late 1990s, China's power automation market has experienced rapid growth. Chinese research institutes and universities have successively developed power automation technologies entirely on their own, and power automation equipment with independent intellectual property rights has also been successfully developed. Domestic power automation enterprises have thus achieved relatively fast development, with an increasingly diverse product lineup, continuously improving service quality, and steadily expanding production scales, marking the entry of the power automation industry into an era of domestic self-reliance.
