This pantograph adopts light weight designing. Some parts use titanium material. Aerodynamic features in high speed service mode is optimized by adding diversion plate and wings. It is used in three domestic technical platform 200km/h “Harmony” EMUs. The satisfactory results have been achieved since business operation of speed raising on April 18.
