The University of Shanghai for Science and Technology harvested two first prizes and four second prizes at the 2019 Shanghai Science and Technology Awards which were announced on Tuesday. Five were led by the university and one second-prize program involved its teachers.
In one of its first-prize programs, a team led by Professor Liu Ping developed a high-performance copper alloy for the production of overhead wires that provide power for high-speed trains.
Team member Zhou Honglei said China had been using German wires in high-speed railways but from 2008 it began to use products developed by the team. With their high electrical conductivity, mechanical strength, thermostability and anti-friction capacity, the wires have enabled China’s high-speed trains to increase their speed from 100 to 400 kilometers per hour. They have also helped produce new output value of over 3 billion yuan in the past three years and saved at least 1 billion yuan in electricity costs each year in the operation of high-speed trains.
Currently, about 70 percent of the railway systems that run at 350 kilometers per hour are equipped with its products.
Professor Liu Ping from USST won the top individual prize at the 2019 Shanghai Science and Technology Awards
