The advanced AC drive technology is adopted. The asynchronous traction motor is suspended rigidly to the bogie frame. Each wheelset is driven by traction motor via floating toothed coupling. The traction effort is transmitted via center pivot.

Dual power supply system, i.e.DC 1500V catenary power supply and DC 800V traction battery power supply which is maintenance free, is applied to the main circuit, to ensure the battery traction is available in the case there is no power supply in the catenary. The locomotive itself is also equipped with traction battery charging system.

Micro-computer control technology is adopted. Advanced foreign MICAS control system improved the control accuracy and reliability of locomotive.

Direct torque control which is of VVVF mode and constant torque starting are introduced to the locomotive traction.

Multiple control function is available which means the control of two locomotives can be realized by one locomotive.

Type DK-1 electro-pneumatic brake is mounted to locomotive air braking system.
