For many years, AerosUSA/Flexa has been a well-known and recognized partner of the railway industry. Our list of customers includes all major manufacturers of railway transportation systems worldwide. A few decades ago metallic conduits dominated the electrical installations of the railway industry. Today, specially designed products made of polyamide, which have to meet the highest international fire and safety standards have become the norm. The design of such specialty products is made in close cooperation with the chemical industry and internationally recognized testing laboratories.

The technical requirements for these conduit systems are constantly increasing as the ongoing development of railway vehicles integrate more applications and therefore more electrical equipment. AerosUSA/FLEXA offers a variety of products dedicated to addressing these increasing requirements.

Exterior Applications

Our highly engineered polyamide conduits are very flexible, yet extremely durable making them ideal for both static and dynamic applications for the railway industry. Whether the application is inside or outside we have the solution for you. The FLEXA ROHRflex conduit exhibits outstanding resistance to UV and weathering at low and high temperatures and retains the ability to endure extreme mechanical stress and impact resistance. Our solutions have surpassed customer expectations in areas where other products fall short. These applications would include underneath the railcar, on the railcar rooftop and for the inter-car jumpers, couplers and bogies. The IP68/IP69K (>NEMA 6P) fittings make for a smooth ride with shock and vibration proof connections to the conduit.
