With the speed increase of Fuxing EMUs, the upgrading of cable fixing auxiliary materials has been accelerated. Recently, the high-modulus glass fiber tape developed by Jiangsu Changhai Co., Ltd. has passed the testing of China Railway Science & Industry Group, with its shock resistance rating increased from 10G (of traditional materials) to 15G, enabling it to withstand continuous vibration at a speed of 350 km/h.

Made of alkali-free glass fiber through weaving and combined with a special resin coating, this material has a tensile strength of 800MPa and also features flame retardancy and aging resistance. Currently, it has been applied in the Beijing-Xiongan High-Speed Railway and Shanghai-Nanjing Intercity Railway, extending the cable maintenance cycle from 2 years to 5 years.
