What is Rail Telecom Cable? 什麼是鐵路電信電纜？

¿Qué es el cable de telecomunicaciones ferroviarias?

Rail telecom cables are specialized communication cables designed for railway trackside applications. These cables form the critical infrastructure that enables train detection, signaling systems, and operational communications across railway networks. According to the Network Rail technical specifications, these cables must meet stringent requirements for electromagnetic compatibility (EMC), environmental resistance, and mechanical durability.

鐵路電信電纜是專為鐵路軌道旁應用設計的專用通訊電纜。這些電纜構成了關鍵的基礎設施，能夠實現列車檢測、信號系統和鐵路網路的運營通訊。根據Network Rail技術規範，這些電纜必須滿足電磁兼容性（EMC）、環境抗性和機械耐久性的嚴格要求。電纜設計壽命通常為25年以上，工作溫度範圍為-40°C至+70°C。
Los cables de telecomunicaciones ferroviarias son cables de comunicación especializados diseñados para aplicaciones junto a las vías del tren. Estos cables forman la infraestructura crítica que permite la detección de trenes, sistemas de señalización y comunicaciones operativas en las redes ferroviarias. Según las especificaciones técnicas de Network Rail, estos cables deben cumplir requisitos estrictos de compatibilidad electromagnética (EMC), resistencia ambiental y durabilidad mecánica.
Key Application: Axle Counter Systems | 關鍵應用：軸計數器系統
Our portfolio includes safety-critical cables connecting trackside axle counters to the AzLM axle counter system, allowing detection of train presence, wagon count, and direction of travel. These cables were developed in collaboration with Network Rail to replace legacy systems while maintaining hardware compatibility and adding rodent protection without metallic steel tape, resulting in superior water blocking properties and a smaller bend radius.

我們的產品組合包括將軌道旁軸計數器連接到AzLM軸計數器系統的安全關鍵電纜，可檢測列車存在、車廂數量和行進方向。
