The inter-turn, inter-layer, main insulation, and side insulation of high-voltage windings must withstand high operating and impulse voltages. Advanced insulation systems and enhanced insulation structures are adopted. The windings are integrally formed through vacuum pressure impregnation or casting to eliminate partial discharge risks and precisely control electric field distribution, ensuring compliance with grid discharge requirements.

Transformer capacity typically ranges from several MVA to tens of MVA. High current and high voltage levels result in significant losses (including copper loss, iron loss, and especially stray losses caused by high-order harmonics). This product adopts an air-duct cooling structure for the windings, providing highly efficient heat dissipation and allowing for a substantial reduction in overall transformer size.

The transformer can be designed with an all-aluminum construction or an integrated structure to reduce overall costs, making the product more competitive.

Multiple reinforcement and vibration-damping measures are implemented to control vibration and noise during operation and transportation.

Widely used in applications such as large-scale electrochemical industries, traction power supply for rail transit, grid-connected testing for new energy power supply, testing laboratories and large-scale scientific facilities, and advanced material preparation, etc.
