Model and its meaning

Structural characteristics
1. The high-voltage winding conductor is made of high conductivity oxygen free copper foil, and the inter turn insulation is made of F-grade insulation material. Both the inside and outside of the winding are made of imported glass mesh plates as the skeleton. Copper foil, along with the insulation of the turns, is assembled in one go on a high-voltage foil winding machine, controlled by a microcomputer, laser positioning, and the lead wires are welded by argon arc welding, wound in sections, and then placed in a mold. The resin with filler is poured into shape under vacuum;
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 along with F-grade turn insulation. During winding, the winding leads are automatically welded with copper bars through argon arc welding before being led out. A support bar is placed in the middle of the winding to form a cooling air passage, and the ends are sealed with resin and solidified into shape;
3. The iron core adopts grain oriented cold-rolled silicon steel sheets, with a 45 degree fully inclined seam and a non perforated iron yoke structure to reduce no-load losses. The iron core clamping adopts a pre-stressed and breathable square steel clamp structure, the core column is tied with insulation tape, the upper and lower clamps adopt an internal pull plate structure, and the surface of the iron core adopts a special resin sealing process, which increases the structural strength and clamping force, while also reducing noise.
Performance characteristics
1. Safe, fire-resistant, and can operate directly at the load center;
2. Adopting T+M technology, it has high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability, and long service life;
3. Low loss, low noise, and significant energy-saving effect;
4. Good heat dissipation performance, strong overload capacity, can increase capacity during forced air cooling operation;
5. Good moisture-proof performance, suitable for operation in high humidity and other harsh environments;
6. Can be equipped with temperature monitoring and protection systems. Adopting an intelligent signal temperature control system, it can automatically monitor and display the working temperature of each three-phase winding, automatically start and stop the fan, and has functions such as alarm and trip settings;
7. Small in size, light in weight, occupies less space, and has low installation costs.
