According to the structure for improving the vibration resistance and the impact resistance of the tower transformer, the tower transformer is a dry-type transformer and comprises an iron core, a low-voltage coil and a high-voltage coil, the iron core is sleeved with the low-voltage coil and the high-voltage coil, and iron core clamps are installed at the upper end and the lower end of the iron core; the transformer is characterized in that all windings sleeved in the low-voltage coil are cast into an integrated structure by resin, an air passage plate is pre-buried between adjacent windings, and the air passage plate is drawn out after casting molding to form a ventilation air passage; an insulating cylinder is arranged between the low-voltage coil and the high-voltage coil; insulation cushion blocks are installed at the two ends of the low-voltage coil and the two ends of the high-voltage coil, the insulation cushion blocks are located between the end faces of the coils and the iron core clamping pieces, pr
