high-voltage insulated load switch for High Speed Rail

high-voltage insulated load switch for High Speed Rail

High-speed rail (HSR) is a type of passenger rail transport that operates significantly faster than the normal speed of rail traffic. In China, high-speed conventional rail lines operate at top speeds of 350 km/h (220 mph). Advanced switches using very low entry and frog angles are also often used.
