The core is made of cold-rolled silicon steel sheets, featuring a 45-degree stepped full斜接缝 structure. Utilizing a three-cut and two-punch core corner trimming process and a five-step stepwise cutting and lamination technique, it improves magnetic flux distribution at the joint and reduces the vibration energy of the core. The core undergoes a one-piece curing process and is sealed with insulating resin, effectively lowering no-load losses, no-load current, and core noise.
High-voltage coils are made with F-grade insulated wire and internationally certified insulation materials, with larger capacity coils featuring axial ventilation channels for heat dissipation. This design offers excellent resistance to current surges, temperature fluctuations, cracking, and superior heat dissipation capabilities. A segmented cylindrical structure is adopted.
Excellent voltage withstand capability and very low partial discharge levels. The coil is vacuum dried after molding before being cast.
The entire casting and curing process is completed according to pre-programmed process curves, with precise process control ensuring the coils are free of air holes and voids.
The low-voltage coil employs a foil structure, effectively addressing the issue of ampere-turn imbalance in wire-wound coils with low voltage and high current. Additionally, foil coils do not have axial turns and winding helix angles, thereby significantly reducing axial forces during short circuits. This ensures that the current density within the coil can be freely adjusted along the axis according to the load distribution of the high-voltage coil, minimizing radial forces during sudden low-voltage short circuits. The ends of the wound coil are sealed and cured with resin, preventing the entry of foreign particles and moisture.
