SH15-M type power transformer
Amorphous alloy is a new type of energy-saving material. Its crystal structure is completely different from that of silicon steel. It is more conducive to being magnetized and demagnetized, thereby greatly reducing no-load loss. Compared with S11 transformers with the same capacity, the no-load loss is reduced by 80%.

It is more conducive to being magnetized and demagnetized, thereby greatly reducing no-load loss. Compared with S11 transformers with the same capacity, the no-load loss is reduced by 80%. and the no-load current drops by about 85%. It is a distribution transformer with ideal energy-saving effect, especially suitable for rural power grids and developing areas where the utilization rate of distribution transformers is low.

5. Installation site: no corrosive gas, no obvious dirt environment;
Note: Products under special environmental conditions can be provided to users according to the agreed conditions.
Core: The magnetic conductive material of the core is made of amorphous alloy. Since amorphous alloys have no crystal structure and have soft magnetic properties, the area of the hysteresis loop is very narrow, the magnetization power is small, the 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 very low. The iron core as a whole is composed of four separate iron core frames in the same plane to form a three-phase five-column type, which must be annealed and has crossed iron reel joints, and the cross-sectional shape is rectangular.
Coil: Low-voltage windings generally use a cylindrical structure made of copper foil except for small capacity (below 160kVA) copper wires; Magnetic small. The high and low voltage windings are wound together into a rectangular coil by a wire tension device, and the coil is solidified into a whole by hot pressing to enhance the mechanical strength of the winding and the ability to resist short circuit.
Fuel tank: It adopts a beautiful fully sealed and maintenance-free corrugated structure. Through the advanced fuel tank production process, strict water pressure leak test and air pressure test, the reliability of the product is ensured.
