2.5 T electric locomotive CAY2.5 6.7.9 GB/smart explosionproof battery type electric locomotive is the company

 

developed second generation of the chopper speed controller electric locomotive (SM 202 smart electric locomotives).

 

Have used the most advanced IGBT chopper controller, adding the driver cab’s space without adding car body’s

 

length, reformed the power box’s lifting device, the locomotive has the characteristics of advancing circuits, simple

 

control, novel structure, simple operation, comfortable and high reliability, low maintenance cost, energy saving etc.
