An accident of 110 kV transformer for anti-short circuit ability is discusses in this paper. A detailed analysis of the accident are discussed. The technique and practice to improve transformer anti-short circuit ability in improving enhance the mechanical strength of the coil axial are discussed. And the advantages of this technique and practice are evaluated. The design requirements

process specifications and technical supervision and management measures with targeted and operability for improving transformer anti-short circuit ability are proposed. The specific recommendations to improving the capacity of the transformer short-circuit for manufacturers are given in structure and key technological aspect.
