. This locomotive was the first Chinese electric main line locomotive, built by the Zhuzhou Electric Locomotive Works with the assistance of the Soviet Union and following the design of the Soviet-H60 electric locomotive (SŽD VL60). The power supply was industrial-frequency single-phase AC, and the axle arrangement Co-Co.

History

The first prototype locomotive, 6Y1-001, which used an ignitron-controlled

rectifier A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The reverse operation (converting DC to AC) is performed by an inve ...

, was produced in 1958. A further 6 prototypes (002 to 007) were produced between 1962 and 1966. A silicon semiconductor-controlled rectifier was used from No. 004 onwards. In response to technology of the French-made 6Y2 locomotive, Zhuzhou Plant made major modification in the design of the 6Y1 locomotive, improving the reliability of the rectifier, traction motors and rheostatic braking system. The eighth locomotive, No. 008, was produced in 1968. The series was also renamed from 6Y1 to SS1 (SS stands for Shaoshan, birthplace of Chinese leader
