Optimization design, improve the filling coefficient of the coil space, the main material (silicon steel sheet, copper wire). Low noise using a new type of main and longitudinal insulation structure, reasonable coil wave process of impact distribution and compound field strength calculation, the application of the computer to carry out dynamic under the anti short circuit ability to verify, to ensure the mechanical strength of products.

35kV series power transformer product design practical, electrical performance and process performance is good.
