【Cable Net News】Academician Lei Qingquan of the Chinese Academy of Engineering predicts that rare earth high-speed rail aluminum alloy cables will inevitably replace copper-core cables.
Global countries are vigorously developing rail transit construction. As high-speed trains step out of China's borders, the country's wire and cable enterprises are poised to embrace endless business opportunities.
Traditional copper-core cables in our country are increasingly unable to meet the construction requirements of high-speed rail in terms of power transmission, safety, and installation costs. Rare earth high-speed rail aluminum alloy cables have a higher single fiber elongation rate, 32% higher than that of copper single fibers, 25%. Replacing copper-core cables is an inevitable trend.
Shanghai Hufei Cable Co., Ltd.'s aluminum alloy overhead cable, developed in 2015, has been tested by a third-party inspection center and all indicators meet national standards.
