Mobile devices because of the movement, need to constantly change the position, in each different location, mobile devices have to be able to obtain power power at any time, otherwise they can not continue to move. At this point, the sliding line came into being. A number of conductors are laid in parallel along the operating orbit of the mobile device and connected to the power supply. On the moving device, a set of electrical appliances that can be charged from the conductor is also installed. In this way, when the device moves, the collector runs synchronously with the device and obtains power from the conductor at any time, which is provided to the device so that the device can continue to move. Devices made up of these conductors and sets of appliances are called sliding lines.
