Rolling Stock Cables

Innovating with lightweight and flexible cable technology

Customer expectations are rising, competition is becoming more intense, and technological advancements are progressing rapidly, which is driving changes in the rolling stock supply chain. 

 

Manufacturers of rolling stock are developing new products and systems to enhance passenger comfort, improve operational efficiency, and ensure safety and speed. 

 

The demand for advanced onboard technology, including better data and power transmission, is increasing the number of cables needed in rolling stock vehicles and carriages. This trend is evident across various modes of transportation, such as trams, underground transit, mass transit lines, and diesel and regional trains.

Polyrad® XT rail and transit cables are designed for original equipment and retrofit applications in power and control circuits and motor leads. These cables provide excellent heat resistance, flexibility, and abrasion resistance, while their reduced size simplifies installation and allows for higher ampacity. 

As the industry's first wire and cable with a dual temperature rating of 125°C/110°C, Polyrad XT single-conductor cables can significantly reduce your inventory by nearly half, all while meeting the requirements of AAR RP-585, ICEA S-95-658, NFPA 130, and many other transit industry standards. Polyrad XT single-conductor cables are available in 600-volt and 2000-volt constructions.

Benefits

Prysmian has developed a high-performance range of technological compounds designed for even the most demanding applications. Our advanced technology offers the following benefits:

  • Compact dimensions while strictly adhering to established performance standards.
  • Capability to operate at higher temperatures with reduced conductor cross-sections.
  • Enhanced physical and mechanical resistance, exceeding standard requirements by up to ten times in areas such as abrasion, cut-through, notch propagation, repeated bending, and vibration resistance.
  • Easy installation, featuring cables with easy-peel properties and low friction, which significantly reduces installation time.
  • Compliance with electromagnetic compatibility (EMC) requirements specific to the railway environment.
  • Unique safety measures to mitigate fire hazards, prioritizing both human and material safety in any working environment. 

Our rolling stock cable solutions aim to minimize fire-related risks. The Polyrad® Rolling Stock portfolio meets all the requirements defined by NFPA 130 for Fixed Guideway and Passenger Rail Systems, including:

  • Maximum flame retardance demonstrated by VW-1 testing.
  • Reliable results in accordance with NFPA 130 and UL Flame & Smoke tests, specifically UL1685 and IEEE 1202.
  • Minimum toxic gas emissions, compliant with BSS 7239.

We understand that train cables must be resilient to various conditions, including exposure to high-speed objects, debris, cleaning fluids, fuels, oils, hydraulic fluids, greases, and more. In addition, they need to endure harsh environmental factors such as extreme temperatures, salt, mud, and UV radiation. All of our cables are designed to meet these essential requirements as standard features. 

Furthermore, we provide a wide range of harnessing solutions that incorporate specially developed compounds and cable designs tailored to meet specific customer needs. How do we achieve this? Through our state-of-the-art technology and the expertise of our skilled technicians and technical specialists.
