For many years, we have manufactured and supplied a variety of railway traction power feeder facilities, power supply equipment for railway stations, and traction power system monitoring facilities to Japanese and overseas railway business operators. Recently, our catenary inspection system began to be used for the inspection of railway facilities other than trolley wires. Further, regarding traction power feeding system, we have developed and supplied rectifier units that apply thyristors to the rectifying elements.
This special issue introduces our products contributing to railway infrastructures at home and abroad and our new technologies that support these products.
