Since 1972, our segment has been assigned to ND2 diesel locomotives imported from Romania. There have been new car approvals over the years and nearly 100 locomotives have been built so far. In this ten years of operation and overhaul practice, according to actual needs, we carried out some necessary retrofitting on this type of locomotive and obtained the more ideal benefit. In particular, some of the electrical transformation projects are more, such as: field rheostat, voltage regulator, counter-current diode circuit, sanding circuit, electrical instrumentation, locomotive Kai, shutdown circuit, and some major contactors, relays Dengjun conducted varying degrees Installation renovation. The transformation of the reasons are as follows: ① imported locomotive accessories
