CRRC Zhuzhou Electric Locomotive Co Ltd, China's biggest manufacturer of electric locomotives by market share, will invest 100 million yuan ($14.45 million) to build six production lines in Zhuzhou, Hunan province, to manufacture high-end rail transit parts by 2020, said its top executive.

Insulated-gate bipolar transistor or IGBT semiconductors will be their key product. The idea is to promote global sales from a long-term perspective.

IGBT semiconductors find applications in a number of areas: bullet trains, smart grids, electric vehicles, new energy products, aerocraft and aviation.
