The invention provides an aluminum dielectric film filling method used for electric power equipment wire clamp connection. A left wire and a right wire are respectively connected with a left wire hoop and a right wire hoop, and a connecting plane between the left wire hoop and the right wire hoop is filled with an aluminum dielectric film by fastening screws, and the aluminum dielectric film is an aluminum sheet metal or an aluminum metal film. The aluminum dielectric film has flexibility, and is capable of being disposed between two wire clamps in a tightly attached manner, and sealing of a gap is guaranteed, and in addition, the aluminum dielectric film is conductive, and therefore the ablation caused by the defective connection between the wire clamps is prevented, and the conductivity of the wire clamps is improved, and in addition, the aluminum dielectric film is suitable for the aluminum dielectric film filling method used for the wire clamp connection.
