FIELD: electricity.
SUBSTANCE: connecting device (1) for electric connection of the first current lead to the second current lead includes the first connection piece (2) for connecting the first current lead and the second connection piece (3) for connecting the second current lead; at that, the first connection piece (2) is connected through flexible connection mechanisms (4), through sliding connection mechanisms or through roller connection mechanisms to the second connection piece so that relative movement between the first current lead and the second current lead becomes possible. The first connection piece (2) is a terminal part for clamping connection to axial movable tie pole, and the second connection piece (3) includes through hole (15) freely pierced with tie pole. Cooling unit (9) for cooling connecting device (1) is connected by means of screw connection to the first terminal part (2). There also opened is interrupter pole insulated with hard electric insulating material and in which the described connecting device is used for connecting tie pole and outgoing circuit output to each other.
EFFECT: providing increased allowable load of the connecting device with sustained current at the remaining similar heating.
