The 10kV fully sealed amorphous alloy three-dimensional wound core distribution transformer utilizes an amorphous alloy three-dimensional wound core as a key component, providing structural support for the coil windings and forming a magnetic circuit. Key features of the product include: a departure from the traditional rectangular planar structure of amorphous alloy cores, innovatively adopting a three-dimensional wound core structure. The core's cross-section is nearly circular, allowing the coil windings to be designed as circular coils, which enhances the transformer's resistance to sudden short circuits. Compared to conventional amorphous alloy transformers, it is more energy-efficient and offers superior resistance to sudden short circuits.
