    FAQ

    Q. How does the "porous heat dissipation shell" improve performance at 10kVA?

    At 32A continuous current, internal heating is substantial. The porous shell design provides: 

    • Maximized surface area for convective heat transfer.
    • Strategic airflow paths that channel cool air across the windings and core.
    • Hot air exhausts throughthe upper vents, creating natural convection circulation. 

    This passive system maintains safe internal temperatures without fans, ensuring long service life and preventing thermal degradation of insulation.
