Rolling Stock

STORIES

OVERVIEW

Linking rolling stock with the latest in lightweight, flexible cable technology

Escalating customer expectations, fierce competition and rapid technological changes are all driving change in the rolling stock supply chain.


Rolling stock manufacturers are looking for new solutions in both product and systems development to meet requirements around passenger comfort, operational efficiency, safety and speed.


Advanced on-board technology requirements, including enhanced data and power transmission mean a growing number of cables are needed on rolling stock vehicles and carriages, including tramlines, underground and mass transit lines, but also diesel and regional trains.

 

As the world leader in the energy and telecom cables systems industry, we’re promoting and driving product development and innovation in the sector. How? Minimizing the size and weight of cables and reducing the wall thickness of insulation and outer sheaths. All whilst maintaining or enhanced performance.


We are the only cable manufacturer offering a full range of products according to EUROPEAN and AMERICAN standards, from power to instrumentation cables, to databus, to pantograph and jumper solutions. Our materials have been specially developed to improve the electrical, mechanical and thermal capabilities, fire performance and life expectancy of the products, using sophisticated advanced technologies.

We offer both alternatives for roof application (TENAX Train Plus), with tinned copper wires screen, and intercoaches (TENAX TRAIN JUMPER) use, with tinned copper braid screen. New lead-free solution is now available.
 
A pantograph (or "pan") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead catenary wire. It is a common type of current collector. Typically, a single wire is used, with the return current running through the track. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings.
Jumper cables are intended for use in railway rolling stock as flexible connection, they may be used both in- and outdoors, e.g. flexible between coaches or between car floor and bogies.

Benefits

We have designed and developed an advanced, high-performing family of technological compounds for even the most demanding applications. Our technology will allow:
 
  • Bending radius to be up to three times the outer cable diameter
  • The smallest dimensions possible, yet in strict compliance with existing performance standards
  • Higher working temperatures with scaled-down conductor cross-sections
  • Higher physical and mechanical resistance, exceeding standard requirements by up to 10 times for properties such as abrasion, cut-through, notch propagation, repeated bending and vibrations
  • Easy installation: our technology and designs provide the cables with easy-peeling properties and low friction between cables, reducing installation time
  • Compliance with EMC requirements for the railway environment
  • Unique safety in case of fire outbreaks
Our focus is always on ensuring both human and material safety in any working environment. Our rolling stock cable solutions are designed to minimise fire hazards related to cables. For example, in order to prevent cables contributing to the spread of fire and the deterioration of the atmosphere (crucial for emergency services) they:
 
  • feature self-extinguishing properties
  • do not release toxic and corrosive gases
  • reduce the amount of smoke emitted.
Our cables are suitable in the most critical conditions (e.g. tunnels, deep metro lines, etc.) and are fully environmentally friendly (LS0H and recyclable).
We understand that cables in trains must be resistant to a wide range of conditions, e.g. high-speed objects and particles, cleaning fluids, fuel, oils, hydraulic circuit fluids, greases, etc, as well as harsh environmental conditions (extreme temperatures, salts, mud, UV irradiation, etc). This functionality comes as standard with all our cables.
 
However, we are also able to manufacture a broad range of harnessing solutions, specifically developed compounds and cable designs (e.g. formulation, compounding and manufacturing cables) according to specific customer needs. How can we do this? Our state-of-the-art technological capabilities and expert technicians and technical specialists.
