Power connection systems for articulated buses

Safe stowing of cables and hoses in the articulation or in vehicle side sections, in ceiling spaces or on the vehicle roof.


In articulated buses, routing cables and hosing from the front segment of the bus to the back section is a particular challenge. Cables and hosing need to move as the vehicle moves but must not under any circumstances kink or break. In addition, excessive wear and tear as a result of the movements of the bus must be avoided in these connecting elements .

The power connection systems for articulated buses from HÜBNER provide a safe, flexible and low-wear means of connection. There are different models and options: For low-floor buses we recommend a power connection system that is located in the roof area of the bus. For high-floor buses, it is preferable to have power connection system in the area of the articulation system itself. Also available in our portfolio: Power connection systems in the side section of the bus as well as weatherproof power connection systems above the folding bellows. The latter option is recommended mainly for trolley vehicles or natural gas-powered buses.

On request, we can equip the front and back parts of the power connection system with bulkhead plates that serve as clear interfaces for the vehicle.


Our power connection systems for articulated buses at a glance:

Power connection in the articulation for high-floor buses

We recommend power connection systems directly in the articulation particularly for high-floor buses. However, they can also be used in other vehicle types.

With the HNGK 19.5 Universal Articulation and the SKD 24.2 Compact Articulation, the hose and cable lines can be routed comfortably through the area of the articulation system without affecting the floor height of the vehicle.  Lines with a diameter of up to 30 mm can be routed directly through the articulation itself. With all other HÜBNER articulation systems or with high-floor buses, the connection lines can go beneath the articulation system.

Power connection in the roof area for low-floor buses

In low-floor buses, placing the complete power connection system below the articulation is often not possible due to the limited space available. The power connections are therefore usually built into the roof area of the bus or the side sections. When the system is placed in the roof, we recommend using a C-shaped power connection system. This configuration helps to avoid movements that can result in the kinking or buckling of hosing.

Power connection in side sections for low and high-floor buses

 When the power connection for articulated buses is made through the side sections of the vehicle, the cables, lines, spiral hosing and tubing are configured so that the various connections remain optimally deployed throughout all movements of the connection section of the vehicle. Other cables and hosing that are already located in the side sections can also be incorporated.

Exterior power connection systems for hybrid, trolley and natural gas buses

In hybrid, trolley and natural gas buses, the lines can be routed outside above the folding bellows. With this type of configuration, we pay special attention so that the power connection system has optimal protection against UV exposure and the effects of the weather. The connection system can also be incorporated in the graphic design of the vehicle. For example, we can overlay the power connection with lateral folding bellow elements that fit with the overall vehicle design.
