The Shaoshan 4 modified (SS4G) electric locomotive is composed of two independent and interconnected locomotive, each locomotive is a complete system.
The main circuit uses four economic half-control bridges and phase-controlled voltage regulation. Traction characteristics with constant voltage or constant current control and resistance braking characteristics with constant speed or constant excitation control.
Air brake adopts dk-1 electric air brake. Each locomotive has two two-axle bogies. Traction motor adopts axle suspension type. The vertical force transmission system consists of two sections of suspension devices, of which the second series uses rubber-metal laminated springs, which has good wave performance. The traction force transmission system adopts a diagonally-pulling low-position tow bar, which has high adhesion performance. The car body widely uses high-strength low-alloy structural steel.
