    Features

    • 3-phase autotransformer has enough power, the wiring is tight and neat, and does not skip turns. Coils adopt insulated H-class enameled wire, with low no-load current and low loss.
    • The 30 kVA dry-type autotransformer has built-in silicon steel sheet, which has good magnetic flux performance, high heat dissipation coefficient and low magnetic loss.
    • The autotransformer uses electrophoresis technology clamps, no burrs on the edges, rounded corners to prevent collisions, and not easy to corrode.
    • Tinned copper tube terminals and rail-type wiring ports are convenient for wiring and ensure that the power-on overload capacity is increased to the extreme.

    Tips: The core and wires of the 3-phase autotransformer winding.

    Winding is the circuit part of 3-phase autotransformer. It works by winding the 3-phase autotransformer by wrapping the insulated flat wire or the enameled round wire. The basic principle is electromagnetic induction.

    • Core: 3-phase autotransformer uses high-quality high-silicon steel sheet. It is primarily made of H18, H14, H12 and Z11. ATO use the most suitable materials that satisfy the customer requirements and conditions of use, and ensure that 3-phase autotransformer performance is designed to its best.
    • Wires: 3-phase autotransformer uses PEW, UEW, EIW, SEIW, EAIW and FEAI enameled wires and fiber-glass covered wires (for high power autotransformer s), with the temperature-resist grade of F (155℃), H (180℃), HC (200℃) and C (220℃). ATO will select the appropriate temperature rating according to the customer's requirements or the customer's environment.
