Structural Features
Iron core:The magnetic material of iron core uses amorphous alloy. Since the amorphous alloy does not have a crystal structure and has a soft magnetic characteristic, the area of the hysteresis loop is very narrow, the magnetization
power is small, the electrical resistivity is high, and the eddy current loss is small, so the no-load loss and no-load current of the transformer made of this material are used. very low. The core is composed of four separate core frames in the same plane
to form a three-phase five-column type. It must be annealed, and it must have a cross-barrier joint with a rectangular cross-sectional shape.
Coil: In addition to using low-voltage windings (160kVA or less) with copper conductors, a cylindrical structure made of copper foil isgenerally used; high-voltage windings use a multi-layered cylindrical structure to balance the winding ampere distribution and magnetic flux leakage. High-voltage and low-voltage windings are wound together with wire tension devices to form rectangular coils, and the coils are solidified by hot-pressing and shaping to enhance the mechanical strength of the windings and the ability to withstand short circuit.
Oil tank: It adopts a beautiful full-sealing and maintenance-free corrugated structure. Through advanced oil tank production technology,it undergoes strict pressure..
