4. Performance characteristics:

4.1 It is safe, fireproof, pollution-free, and can be directly operated in the load center.

4.2 Adopting Swiss T+M technology, with high mechanical strength, strong short-circuit resistance, low partial discharge, good thermal stability, high reliability and long service life.

4.3 Low loss, low noise, obvious energy saving effect, and maintenance-free.

4.4 Good heat dissipation performance, strong overload capacity, and capacity operation can be increased when forced air cooling.

4.5 Good moisture-proof performance, adapt to high humidity and other harsh environments.

4.6 It can be equipped with a complete temperature monitoring and protection system. Using intelligent signal temperature control system, it can automatically monitor and circulate display the respective working temperature of the three-phase winding, can automatically start and stop the fan, and have alarm, trip and other function settings. 4.7 Small size, light weight, less space and low installation cost.

5. Structural features:

5.1 The high-voltage winding conductor adopts high-conductivity oxygen-free copper foil, the turn-to-turn insulation adopts F-class insulating material, and the inside and outside of the winding are made of imported glass grid plates as the skeleton. Copper foil and turn insulation are programmed once on the high-voltage foil winding machine, controlled by microcomputer, laser positioning, lead wires are automatically welded by argon arc welding, segmented It is wound and then placed in a mold, and molded with resin with filler under vacuum.

5.2 The low-voltage winding adopts copper foil with the same height as the low-voltage winding, and is wound on the low-voltage foil winding machine together with class F turn insulation. When winding, the lead wire of the winding is automatically welded by argon arc welding with a copper bar, and a stay is placed in the middle of the winding to form a cooling air passage, and the end is potted with resin and solidified.

5.3 The iron core is made of high-quality grain-oriented cold-rolled silicon steel sheet, 45-degree full oblique joints and iron yoke non-perforated structure to ensure low no-load loss. The iron core clamping adopts the unique domestic prestressed and ventilated square steel clip structure, the core column is tied with insulating tape, the upper and lower central parts adopt the inner pull plate structure, and the iron core The surface adopts a special resin sealing process, so the structural strength and clamping force are increased, and the noise is also reduced.
