Improved performance and safety with multilayer conduits for the rail industry

16-04-2026

Our new innovative railway engineering multilayer product line provides protection and safety for cables on intercarriage jumper connections, bogies, roof installations and under-carriage installations.

The new PMA multilayer technology allows combinations of materials for optimal product characteristics in rail applications.
An innovative multilayer manufacturing technology creates a corrugated conduit with two layers of material. This multilayer solution provides additional protection and safety thanks to the combination of two specially modified polyamides with different material characteristics.
The new material combinations significantly improve the overall performance of the conduits.

To meet all customers‘ application requirements and provide full planning flexibility, PMA offers two different multilayer solutions for the rail industry:

The highly flexible XPCSF conduit with orange inner layer meets the highest classification of EN45545-2, HL3 according to requirement set R22  allowing use in external dynamic applications such as, roof installations, inter-carriage jumper cables, undercarriage and bogies on all train design categories and any operation category.

The very flexible XPCS conduit with green inner layer meets EN45545-2, HL2 according to requirement set R22 and NFPA 130 allowing use in external dynamic applications such as, roof installations, inter-carriage jumper cables, undercarriage and bogies.

The key benefits:

• Excellent resistance to UV and weathering
• Outstanding ageing characteristics.
• Wear indication through coloured inner layer

A new standard in comprehensive end-to-end cable protection solutions

Together with PMA‘s tried and tested product range of fittings and accessories in various sizes, the XPCSF, XPCS, XPCSL and XVCSF conduits with new state-of-the-art multilayer technology offer a comprehensive and sustainable end-to-end cable protection solution for the rail industry.
