Product Introduction

Amorphous alloy core has such a lot of advantages as low loss (equivalent to 1/3-1/5 of silicon steel sheet), low coercive force, low excitation current and good stability against temperature change. Therefore transformers made of amorphous alloy has significantly good performance in energy saving, particularly suitable for low load uses like rural areas and developing regions. SH15 amorphous alloy transformer, of which the core adopts three phases three poles or three phase five poles cores, core clamping uses sheet forming frame structure, low voltage coil adopts foil winding type, giving the transformer advantages including low loss, strong resistance to short circuit, advanced structure and world advanced performance.

 

Product Features

1. Magnetic material of the core is amorphous alloy. Since that amorphous alloy has no crystal structure while having soft magnetism, the magnetic hysteresis loop is very narrow, magnetizing power is low, resistivity is high and eddy current loss is small, no-load loss and current of transformers made from this kind of material are both very low. The load loss of S(B)H15 amorphous transformers is equivalent to that of S11 normal oil transformer series while no-load loss of the former is about 65% lower than that of the latter and no-load current about 70% lower, making average annual operation cost of the amorphous S(B)H15 series about 30% lower than the S11 series.


2. The low voltage winding is usually made into a cylinder wound by copper foil while the high voltage winding often adopts a multi-layer cylinder structure so that the ampere-turn can evenly distribute with low magnetic leakage. The high and low voltage windings are wound together by tension device into square coils which are solidified into a whole through hot compression shaping to increase mechanical force and resistance to short circuit of the windings.

 

3. The totally-sealed structure prevents the insulating oil and insulating medium from contacting with air. Added with the craftsmanship of vacuum drying and oil filtration, there is no need to change oil in normal situations, greatly reducing the maintenance cost and prolonging the mechanical life of the transformer. What’s more, the transformer can be operated in wet environment, making it an ideal power distribution facility in urban and rural distribution network.
