Line protection measurement and control device is simply illustrated that is the device used for the line cabinets and outlet cabinets for protection and measurement .our Company with strong technical research and development strength and a good business management system, already had the very perfect 110KV and the below voltage grade microcomputer product line of the line protection, The main circuit protection products contain 9411 economic type line protection and control device, 9511 standard line protection, and control device, 971 high-end line protection, and control device, 994 line differential protection and control device, 997 line optical fiber longitudinal difference protection and control device, 987 line distance protection and control device. Since the company was founded in 8 years, by dint of the down-to-earth style of work, a good sense of service and reliable product quality, rapidly increased business, now the related computer line protection device annual sales have exceeded 3000, the products have been widely used in electric power, hydraulic, State Grid, China Southern power grid and so on many national key projects.
