- 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 15 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: 3-phase autotransformer applications.
3-phsae autotransformers are widely used in applications where primary and secondary isolation are not required. Common AC (manual rotating) voltage regulators, transformers in small household AC voltage regulators, transformers in three-phase motor auto-decompression starter boxes, etc., are all application examples of 3-phase autotransformers.
With the rapid development of power systems in the direction of large capacity and high voltage, 3-phase autotransformers have been widely used in high-voltage power networks due to their advantages of low price and high efficiency, becoming voltage conversion equipment for transmitting important electrical energy. As one of the most important equipment in the high-voltage power grid, 3-phase autotransformer is of great significance to ensure the safe and reliable operation of the power grid and the flexible distribution of electrical energy. With the rapid development of high-speed railways, the reliability of 3-phase autotransformers is also crucial to the safe operation of high-speed railways.
