The invention relates to a powered guide chain system (1), comprising a powered guide chain (3), for guiding cables (4), hoses or the like between a stationary and a mobile connection point, a driver (7) to which the powered guide chain (3) is connected via the mobile connection point, and a guide channel (8), which comprises a hollow profile with a passage (9) for the driver (7), extending in the longitudinal direction, whereby the powered guide chain (3) is guided into the guide channel (8) in the longitudinal direction thereof, forming two runs which are guided parallel to each other and connected to each other via a deviation area. The invention also relates to a sliding door system (2) for a vehicle, provided with said powered guide chain system (1). The aim of the invention is to obtain an easy and safe guidance of cables (4), hoses or the like in at least two directions. Said aim is achieved, whereby the driver (7) comprises a mobile arm (12) which protrudes from the guide channel (8) with a fastening side (13) for connection to a device movable in relation to the guide channel (8), the distance between the fastening side (13) and the guide channel (8) being changeable in a travel component transverse to the longitudinal direction of the guide channel (8).
