Kanger has a transformer with independent intellectual property rights, low energy consumption, high efficiency, and small size. The transformer uses a large cross-section high-frequency soft ferrite core and a copper high-frequency bundled wire, and uses a unique interlaced winding process. When operating under high frequency conditions, iron loss and copper loss are small, and the heat generation is extremely low. Only air cooling is enough to avoid water cooling. The harm caused by oil cooling.
