4. Performance Features:

4.1 Safe, fireproof, pollution-free, can operate directly at load centers.

4.2 Uses 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, significant energy-saving effect, maintenance-free.

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

4.5 Good moisture resistance, suitable for operation in high humidity and other harsh environments.

4.6 Equipped with a complete temperature monitoring and protection system. Uses an intelligent signal temperature control system that can automatically monitor and cyclically display the operating temperature of each of the three-phase windings, automatically start and stop fans, and has alarm and trip function settings. 4.7 Compact size, light weight, small footprint, low installation cost. 4.8 Equipped with remote monitoring function to grasp the equipment operating status in real time.

5. Structural Features:

5.1 The high-voltage winding conductor uses high conductivity oxygen-free copper foil, with inter-turn insulation made of F-class insulation material. Both inside and outside of the winding use imported glass mesh boards as the framework. The copper foil along with inter-turn insulation is programmed once on a high-voltage foil winding machine, controlled by microcomputer, laser positioned, and the lead wires are automatically welded by argon arc welding. The winding is segmented and then placed into a mold, where it is cast and formed under vacuum with resin containing fillers.

5.2 The low-voltage winding uses copper foil of the same height as the low-voltage winding, wound on a low-voltage foil winding machine together with F-class inter-turn insulation. During winding, the winding leads are automatically welded with copper bars by argon arc welding and led out. Cooling air channels are formed by inserting support bars in the middle of the winding, and the ends are sealed with resin and cured.

5.3 The core uses high-quality grain-oriented cold-rolled silicon steel sheets, with 45-degree full miter joints and yoke perforation structure to ensure low no-load loss. The core clamping uses laser-cut steel plate bent clamp structure, the core column is tied with insulating tape, upper and lower clamps use internal pull plate structure, and the core surface is sealed with a special resin process, which increases structural strength and clamping force while reducing noise.
