Product Description

In recent years, with the expansion of amorphous alloy transformers worldwide, the industry market size has grown rapidly. Currently, amorphous alloy transformers are widely praised globally. Countries such as the United States, Canada, Mexico, Japan, India, and South Korea have a large number of amorphous alloy transformers in operation. According to statistics, the global market size of amorphous alloy transformers was 904 million US dollars in 2021, and it is expected to reach 1.718 billion US dollars by 2031, with a compound annual growth rate of 6.63%.

With the increasing emphasis on energy conservation and emission reduction, amorphous alloy transformers have gained popularity in the market due to their outstanding energy efficiency and environmental friendly characteristics. The demand for them has generally shown an upward trend in recent years. The amorphous alloy 300kva oil immersed transformer is made of amorphous alloy material and features a three phase five column structure. The cross section of the core material is rectangular. The thickness of the material is only 0.02 to 0.04 millimeters. It is made using the advanced "planar casting method". This silicon copper sheet material, with its crystal structure, has excellent magnetic properties, no crystal defects, and extremely low magnetization power. Moreover, the low voltage coil is of an aluminum foil winding type, featuring strong short circuit resistance and an advanced and reasonable structure.

Amorphous Alloy 300kva Oil Immersed Transformer

Technical parameter:

Item Name	amorphous alloy 300kva oil immersed transformer
Rated Power	300 kVA
Phase	3 Phase
High Voltage (HV)	10kV
HV Tap Range	±2×2.5%
Low Voltage (LV)	0.4kV
Vector Group	Dyn11 / Yyn0
No load Loss (P0)	160 W
Load Loss (Pk,75℃)	3420 W

Product features:

1. The amorphous alloy 300kva oil immersed transformer core is made by rolling amorphous alloy strips. The no load loss is reduced by approximately 75% compared to the S9 type transformer.

2. The low voltage part of the transformer uses copper foil coils to enhance the transformer's ability to withstand short circuits.

3. The connection group of the amorphous alloy 300kva oil immersed transformer is Dyn11, which reduces the impact of harmonics on the power grid and improves the power supply quality.

4. The transformer is filled with oil under vacuum, which can completely eliminate air bubbles in the coils and ensure stable insulation performance. Before each amorphous alloy 300kva oil immersed transformer is put into use, a full wave lightning impulse test with a peak voltage higher than the national standard by 25% is conducted to ensure the safe and reliable operation of the transformer.
