Shenxing Cable: Providing Reliable Arteries for High-Speed Trains

Project Background:

As an important part of modern transportation, high-speed trains have extremely strict requirements on cable performance. High-speed operation, high-frequency signal transmission, harsh environment and other factors have posed great challenges to the reliability of cables. Shenxing Cable, with years of technical accumulation and in-depth understanding of the high-speed rail industry, provides customized cable solutions for high-speed trains.

Shenxing Solution:

▶ High-frequency signal cable: Shenxing provides a dedicated high-frequency signal cable for the high-speed train signal system. The cable uses a new low-loss insulation material and shielding structure, and has the following outstanding features:

• Ultra-wideband: Covering the DC to 10GHz frequency band, it meets the needs of high-frequency signal transmission for 5G communication, on-board entertainment systems, etc. of high-speed trains.

• Low attenuation: Adopting foamed polyethylene insulation material, it effectively reduces signal transmission loss and ensures signal quality.

• Excellent anti-interference: Adopting multi-layer shielding structure and combining grounding technology, it effectively suppresses external electromagnetic interference and ensures the stability of signal transmission.

• Compliance with international standards: It meets relevant international standards of the railway industry (such as IEC 60227, IEC 60332, etc.) and has passed strict railway certification.

▶ High temperature and cold resistant cables: The operating environment of high-speed trains is complex and the temperature changes dramatically. Shenxing's high temperature and cold resistant cables use cross-linked polyethylene insulation materials, which have excellent heat resistance and cold resistance. They can operate stably for a long time in the extreme temperature range of -40°C to +120°C, and have passed the thermal aging and low temperature bending tests of relevant standards of the railway industry. In addition, we also use a special flame retardant formula to ensure that the cable can delay the spread of fire in the event of a fire and ensure the safety of the train.

▶ Vibration and fatigue resistant cables: The vibration generated by the high-speed operation of high-speed trains has a great impact on the life of the cable. Shenxing's vibration and fatigue resistant cables use high-strength aramid fiber reinforced materials with excellent tensile strength and fatigue resistance. In order to further improve the vibration resistance of the cable, we use a special damping layer in the cable structure design to effectively absorb vibration energy.

▶ Weather-resistant cables: High-speed trains are often exposed to harsh natural environments. Shenxing's weather-resistant cables use special sheath materials with excellent UV resistance, ozone resistance, oil resistance, water resistance and other properties, and can adapt to various harsh climate conditions.

Application cases:

• A high-speed railway: Shenxing provides a full set of cable solutions for the railway, including cables for traction transformers, cables for signal systems, cables for lighting, etc. By adopting Shenxing cables, the electrical system of the railway operates more stably and reliably, greatly reducing maintenance costs.

• A train set: Shenxing provides a customized cable solution for the train set, meeting its needs for lightweight, high performance, and high reliability. By adopting Shenxing cables, the operating efficiency of the train set has been significantly improved.

Technological innovation:

• Intelligent monitoring system: Shenxing is developing an intelligent monitoring system based on the Internet of Things technology. By embedding sensors in the cables, the operating status of the cables can be monitored in real time to achieve fault warning and remote maintenance.

• Application of new materials: We are actively exploring the application of new materials, such as nanomaterials and bio-based materials, to further improve the performance and environmental friendliness of cables.

Summary: 

Shenxing Cable has won the trust of many high-speed rail customers with its excellent performance, reliable quality and perfect service. In the future, Shenxing will continue to increase R&D investment to provide more advanced and reliable cable solutions for the high-speed rail industry and contribute to my country's high-speed rail industry to the forefront of the world.
