As the main product for railway contact network, composite post insulator is widely used in complex electrified railway tunnel. It can effectively prevent pollution flashover accidents, reduce the workload of cleaning and maintenance. Because of small size of composite post insulator, especially when the tunnel clearance is small, there is no substitute for porcelain and glass insulators.
