PMA® FLEXIBLE PROTECTION SYSTEM MULTILAYER SOLUTIONS

Improved performance and safety through innovative multilayer technology

PMA® MULTILAYER CONDUITS FOR THE RAIL INDUSTRY

Multilayer conduit with inner and outer layer for improved safety and performance. 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.

KEY FEATURES AND BENEFITS

<p>ABB's PMA multilayer conduits use advanced multi-layer extrusion technology to combine different polyamide materials in a single conduit, delivering enhanced mechanical performance, UV resistance and fire safety for demanding dynamic and static applications.</p>

Durable

<p>Two- and three-layer material combinations deliver excellent mechanical characteristics including high compression resistance, very good reversed bending resistance and high impact strength even at low temperatures and low humidity</p>

UV-resistant

<p>PA12 outer layer on XPCS, XPCSF and XVCS2H conduits delivers excellent UV resistance and weathering characteristics for reliable long-term performance in external rail and infrastructure applications</p>

Safe

<p>Coloured inner layer on all multilayer conduits provides a wear indication function — a visible signal that the conduit outer layer is worn and replacement is required, preventing undetected failure in critical installations</p>

Versatile

<p>Eight conduit types cover static and dynamic external railway applications, interior passenger zone installations and high-cycle robotics and automation environments, all compatible with PMAFIX Pro, PMAFIX and PMA Smart Line fittings</p>

Reliable

<p>Temperature ranges from -50°C to +105°C continuous depending on conduit type, with short-term ratings up to +160°C, for sustained performance across extreme climatic and industrial operating conditions</p>

Fire safety

<p>Temperature ranges from -50°C to +105°C continuous depending on conduit type, with short-term ratings up to +160°C, for sustained performance across extreme climatic and industrial operating conditions</p>

Compliant

<p>Certifications include EN 45545-2 HL2 and HL3 (R22 and R23), NFPA 130, BSS 7239/SMP 800-C, UN Regulation No. 118, UL 1696, CSA C22.2 No. 227.3-05, REACH and RoHS</p>
