    FAQ

    Q1: Can the voltage configuration of this 45 kVA 3-phase autotransformer be customized?

    Yes. While the standard setup converts three-phase 380V input to 220V or 200V output on both 50Hz and 60Hz systems, custom input and output voltage configurations are available. This makes the 45 kVA autotransformer suitable for a broad range of applications beyond the standard step-down configuration.

    Q2: What winding material options are available, and how do they affect performance?

    This dry-type autotransformer is available with either copper or aluminum winding. Copper offers superior conductivity and efficiency, while aluminum provides a more cost-effective alternative. Both are wound tightly with H-class insulated enameled wire to ensure low no-load current, minimal loss, and high working reliability across the full 45 kVA capacity.
