October late, Tianjin special Variable Electrical Transformer Limited development and production of the "nuclear safety-resin cast dry-type transformers", adopted in the organization of the expert group identification.

　　The main technical features of the product: 1, were trapped under the transformer, core, between the legs at the end with epoxy resin casting, as a whole, reducing vibration in various parts of relative movement, and improving the overall mechanical strength and seismic performance; 2, between the core and coil shoring tight low pressure using a two-tier structure of H-class middle of a layer of insulating material silicone pad structure; 3, high, low voltage coil of shoring structure using flexible positioning tight to protect products during coil shock no displacement; 4, meet GB1094.11-2007 (IBC60076-11), C2, E2, F1's request.
