As < 0 > of popularization and application, its manufacturing technology is also obtained great progress, can be predicted, the future of < 0 > will obtain further development in the following aspects: [2] [3] (1) the energy conservation and low s/n: as the new low silicon steel sheet, foil type winding structure, ladder core juncture, environmental protection requirements, the noise research thorough, and computer optimization design of the introduction of the new material, new craft, new technology, will make the future of dry type transformer more energy-saving, more quiet. (2) high reliability: improve product quality and reliability, will be people's unremitting pursuit. (3) environmental protection characteristics certification: on the basis of the European standard HD464, to carry out the research and certification of the dry type transformer's climate resistance (C0, C1, C2), environmental resistance (E0, E1, E2) and fire resistance (F0, F1, F2) characteristics. (4) capacity: from 50 ~ 2500 kva distribution transformer dry type transformer, to 10000 ~ 20000 kva / 35 kv power transformer is extended, as the city power load increasing, the city of substation network area is more and more into the city, residential quarters, large load centers such as factories and mines, 35 kv large area power supply power transformer center will receive a wide range of applications. (5) multi-functional combination: from a single transformer to a multi-functional combined transformer development with air cooling, protective shell, temperature computer interface, zero-sequence transformer, power metering, closed bus and side outlet. (6) Multi-field development: from distribution transformers to power plant transformers, excitation transformers, subway traction rectifier transformers, high-current furnace transformers, nuclear power plants, Marine transformers and oil production platforms and other special transformers and multi-purpose fields. Among them, the dry traction transformer used in urban subway and rail transit has three grades of voltage of 10, 20 and 35kV, and capacity of 800, 2500 and 3300kVA. In order to reduce harmonic pollution, it has developed from 12 pulse rectifier to 24 pulse rectifier. The exciting transformer of the world's largest 84000KW generator in the Yangtze Three Gorges has been successfully developed by Shunte Factory and passed the national acceptance. It can be predicted that the distribution transformer of the 21st century will belong to the resin insulated dry type transformer with superior performance, low noise and energy saving
