NEW 25 KV-50 HZ 5400 KW CC ELECTRIC LOCOMOTIVES FOR THE CHINESE RAILWAYS

In 1960 the Alsthom and MTE Companies delivered 25 standard gauge CC locomotives, of the 6Y2 series, to the Chinese Railways. These locomotives are supplied at 25 kV 50 Hz single phase and the conventional series-motors take undulating current supplied from the line at variable voltage through a transformer and SW Ignitron type rectifiers. These locomotives are still giving excellent service and the Chinese Railways again demonstrated their confidence in French equipment by ordering, in 1970, 40 additional locomotives of the same design. However, these are substantially more powerful, being rated at 5400 kW at the rim instead of 4000 kW. Like their predecessors they can be multipled in pairs. Of course they incorporate the latest progress in electrotechnology and the traction current for the motors--one per axle--will this time be rectified by thyristors. For trial purposes two of the locomotives will be equipped with regenerative braking, a natural consequence of the thyristor rectifiers.
