Supplying 60% of the Beijing–Shanghai High-Speed Rail's Fiber Optic Network, ZTT is Powering Global Railways

As the world embraces rapid technological advancements, the demand for reliable, safe, and efficient transportation systems has never been greater. Railways, in particular, play a crucial role in connecting cities, fostering economic growth, and improving the quality of life for millions. At the forefront of this transformative journey is Zhongtian Technology (ZTT), a company committed to powering the railways of today and tomorrow with innovative solutions.

?

One of the most iconic examples of ZTT’s contribution to modern rail infrastructure is the Beijing–Shanghai High-speed Railway. This rail line, among the longest and highest-standard high-speed railways globally, has revolutionized travel between these two major cities. As one of China's most significant infrastructure projects, it has not only made travel faster, more convenient, and comfortable but has also catalyzed economic and social development along its route.

ZTT played a crucial ?role in this monumental project by supplying 2,583 kilometers of fiber optic cable, which accounts for about 60%?of the total used in the railway. This contribution provided critical technical support for the railway's communication safety.

ZTT’s offerings extend far beyond the Beijing–Shanghai High-speed Railway. The company has supplied an array of products, including power cables, optical cables, and power conductors, to support the rapid development of railway electrification and urban rail transit across China. ZTT’s comprehensive railway cable solutions have been successfully implemented in numerous projects, including the Qinghai-Tibet Railway, Beijing-Guangzhou Railway, Zhejiang-Jiangxi Railway, Harbin-Dalian High-speed?Railway, Shanghai-Kunming High-speed?Railway, and over 100 metro lines nationwide. These products are also making an impact globally, with exports reaching countries like Thailand, Argentina, South Africa, and Qatar.

So, what makes ZTT’s railway cable products stand out in the market? The answer lies in our meticulous design, which prioritizes the highest safety standards. For instance, ZTT’s railway ground wires utilize seamless forming technology and are equipped with highly corrosion-resistant outer sheaths, ensuring unified grounding for signal equipment and facilities. This design safeguards both equipment and personal safety. In areas with strong electromagnetic interference, ZTT’s railway digital signal cables, created using a physical foaming process, significantly reduce line attenuation and meet the new demands of high-speed railway signal control. The high-purity copper tape developed by ZTT enhances the shielding performance of railway digital signal cables, reduces crosstalk interference, and ensures the accuracy of railway signal transmission.

Moreover, the safe operation of trains relies heavily on the power and signal transmission of various onboard electrical equipment. ZTT’s power and control cables for railway vehicles are heat-resistant, frost-resistant, and capable of withstanding exposure to various acids, alkalis, and oils. Their exceptional flame-retardant and fire-resistant properties meet the stringent standards set by European, German, and American regulations.

As the digital age progresses, there is an increasing demand for not only ensuring train safety but also for providing seamless mobile communication during travel. ZTT is dedicated to offering specialized solutions for railway communication signal coverage, allowing passengers to enjoy a stable mobile communication experience, even at high speeds. ZTT’s LTE-M leaky coaxial cable, which combines feeder transmission and antenna transceiver functions, effectively addresses the challenge of wireless field strength coverage in long, narrow, enclosed spaces. Additionally, ZTT’s flexible radiation-type leaky coaxial cables, designed with precise simulation, ensure stable electromagnetic radiation and a significant increase in MIMO bandwidth, providing a smooth and stable data transmission channel for the next generation of mobile communication networks.
