RADOX® cables support EV gangway applications

To ensure that no magnetic fields could escape, the cables had to have adequate shielding for maximum protection. Compounding this issue was the fact that, historically, no EV component had ever been designed to move with the bus joint.

For our solutions to be used within the project, HUBER+SUHNER had to provide a cable that would work efficiently within the test rig set up by the customer and demonstrate optimal cable durability. 

Beyond testing, the durability of the cables would be essential once in operation. Any cable supplied to the project would be subjected to harsh environments and exposure to the sun and UV lighting, so capabilities that would protect the solution from these elements would prove crucial.

HUBER+SUHNER had already used this cable technology within railway applications – where cables also experience harsh conditions, quick movements, and vibrations. We were confident the same solutions could work in articulated electric buses, despite the unique mechanical demands. We also have long-standing experience in this area, having worked with successful OEMs in the past.

For the project, HUBER+SUHNER provided the customer with our screened RADOX® 155 / RADOX Elastomer S cables designed specifically for flexible and dynamic use. Our automotive single-core screened highly flexible cables are UV-resistant with a broad temperature range, meaning they will work optimally in harsh conditions while requiring no additional protections, such as corrugated tubing. The solution’s insulated design also provides maximum protection for the shielding braid against potential damage, meaning it was perfectly suited for the electric buses involved in the project.

The quality of our screened RADOX® cables was demonstrated during the customer’s testing process. When routed over a joint in the special mounting loop, our solution was found to offer the strongest mechanical resistance out of all cables the customer tested.

Our engineering expertise also meant we could place the HV assemblies onto the roof to ensure customer cost savings on top of the performance benefits. 

As a result, not only did our cables pass the field test, but they were also used as a solution for serial bus ranges. It has now been used as a standard in these vehicles since 2018. Since its implementation within the buses, the screened RADOX® cables are still functioning perfectly even over a cumulative 1.5 million kilometres in operation.

The mechanical strength of our solution – among other key benefits – has enabled HUBER+SUHNER to become the most successful supplier in this field within the market. Looking ahead, the exceptional and competitive cable strength offered by screened RADOX® cables is poised to extend its application across the construction vehicle sector, complementing the enhancements we already provide for buses and trucks.
