High-speed rail cable Jiangsu build   Breaking foreign technological blockade with independent innovation

In the past, the construction of high-speed railway in China is the French UM71 railway signal cable; nowadays, Wang Zichun, the chairman of the Jiangsu Dong Qiang Co., Ltd, who leads the team to innovate indenpently. The research and development of high performance railway digital signal cables not only breaks technological monopoly of the foreign enterprises, but also saves hundreds of millions of yuan for national railway construction every year.

Wang Zichun said that the staff work for two-thirds hours a day to reduce the media constant, the capacitance and the attenuation. Thus, the requirement of the long-distance transmission is achieved..

In that year, Wang zichun won “the second prize of national science and technology progress”. Getting such a heavyweight award alsomakes him more aware of the significance of scientific and technological innovation for businesses. Since 2013, the company has invested 150 million yuan to develop special cable projects of aluminum alloy. This October, a high-performance data cable developed by Dong Qiang company has spent two years. The transmission frequency has exceeded the high frequency 2G Hertz, which has increased the original transmission speed by nearly 7 times. The product not only fills the domestic gap, but also its core technology is at world leading level. Now, under his leadership, the company has formed an innovative mechanism and culture.And it has developed into a state key high-tech enterprise.

Wang Zichun said, every year, there are more than 6 new products through the provincial appraised. Each national railway has Dong Qiang railway signal cable. And 12 meters per 100 meters is the product of this company.
