The invention relates to the field of power supply high voltage bag production equipment, in particular to a power supply line and a vacuum filling device provided with the power supply line. A gap between a line core and a line core coating layer is sealed by using epoxy resin, meanwhile, the power supply line and a box body are sealed, electric conduction can be realized, and air in the gap between the line core and the line core coating layer of a guide line is prevented from entering the box body. Compared with traditional direct sticking into the box body by using the guide line, air is prevented from entering a sealing box from the connection position between the power supply line and the sealing box and the gap between the line core and the line core coating layer, so that a high pressure bag after filling does not contain air impurities, and the defective product rate of the high voltage bag is reduced; meanwhile, the service life and safety of the high voltage bag are furtherimproved, the air in a hi
