ZTT Accounted for 60% Telecom Cables Share of Beijing-Shanghai High Speed Railway


ZTT Group - leading global manufacturer of cable systems, accumulatively provided 2583km telecom cables accounting for 60% telecom cables share of Beijing-Shanghai High Speed Railway, which provided massive technical support for railway telecom security. As a high-speed railway constructed after the establishment of the People’s Republic of China with high standard, long mileage and large investment, Beijing-Shanghai High Speed Railway not only makes travelling easy and convenient for people, but also has positive effects for social economy along the railway.


ZTT supplied fire retardant and directly buried optical fiber cable to Beijing-Shanghai High Speed Railway. Besides the basic function of low smoke zero halogen, fire resistance, moisture resistance, anti-rodent and anti-termite, all these cables possess outstanding flame retardant and anti-pressure capability. The functions of optical and mechanical property were beyond customers’ requirement, making customers very pleased.


Mr. Bao Degui, general manager of ZTT Railway said, besides optical fiber cable, other products like OPGW, power cable, conductor from ZTT were also used in Beijing-Shanghai High Speed Railway. With the development of the railway construction, ZTT provided series of products like optical fiber cable, leaking cable, signal power cable, rail and vehicle use cable through the metro lines for railway cable solutions. ZTT optical fiber cables were also widely used on other high-speed railways like Qinghai-Tibet Railway, Beijing-Guangzhou Railway, Zhejiang-Jiangxi Railway, Harbin-Dalian Railway, and Shanghai-Kunming Railway and so on, and provided better service over one hundred metro lines for Chinese railway construction. ZTT optical fiber cables were also exported to a lot of foreign countries, such as Thailand, Argentina, South Africa, Iran and so forth.


Why ZTT cables are so popular? Mr. Liang Bin, CTO of ZTT railway industry chain responded: ZTT is adequately concerned about the safety for high-speed railway products during R&D activities. For example, the railway links up grounding wire provided by ZTT, adopts integral seamless forming technology with high antiseptic property, and the relevant outer sheath possesses strong anti-corrosion performance to make signal equipment unified grounding for protecting safety of equipment and personal safety. In electrified sections or strong electromagnetic interference regions, ZTT railway digital signal cable applies the sheath-foam-sheath physical foaming technology. It can greatly reduce the attenuation of cable line to meet the new requirements in the signal control range of high speed railway. ZTT highly purified electrician copper strips can greatly enhance internal shielded railway digital signal cable shielding performance, reduce the crosstalk interference, break the limitation of same frequency with different cable, so as to ensure the accuracy of railway signal transmission. Each electric equipment for power and signal transmission also has important influence on the train safety, ZTT innovated vehicles use power cable and control cable, which possess heat-resistant anti-freeze, and resistant to acid and alkali and erosion of grease, the excellent flame retardant, fire-resistant performance meet the strict request for European standard, German standard, American standard.


With the high speed development of internet, people not only pay attention to travelling safety, but also have higher demand for the railway mobile telecom. Mr. Liang Bin emphasizes, ZTT has been devoted to providing professional solutions for rail transit communication signal coverage, making more convenience and better experience on the internet for customers and make the train travellers convenient to use mobile communication equipment with no fidelity and connection loss, ensure good experience with network. And the LTE-M leaky cable, R & D by ZTT, set feeder line transmission and antenna transceiver function into an organic whole, and give the perfect solution about narrow and long confined space strongly covered by wireless field. ZTT Flexible Radial Coaxial Leakage Cables through accurate simulation design, and guarantee the stability of electromagnetic radiation, to realize the multiplied improvement of MIMO bandwidth, offering smooth and stable data transfer channels for the next generation of mobile communication networks.


ZTT is actively researching and developing higher speed auxiliary products for high-speed railway, for developing more new technology to promote the development of Chinese railway industry!
