The utility model provides a resin insulation 3D iron core dry type transformer equipped with a new lead-in wire structure. The transformer includes a 3D iron core fixed between an upper clamp and a lower clamp, a low voltage coil and a high voltage coil winding on the iron core, a high voltage insulator and a low voltage insulator. The transformer is characterized in that the upper clamp is provided with a channel steel, on which is arranged the low voltage insulator, the first lead wire of each phase of the high voltage coil is connected to the tail lead wire of another phase of the high voltage coil via a lead wire, the lead wires of the two phases of the low voltage coil a, c far from the channel steel are connected to the two low voltage insulators at the left and right of the channel steel via connecting lead wires, the first lead wire of the phase of the low voltage coil b close to the channel steel is connected to the low voltage insulator in the middle via a connecting lead wire, the three phases of
