Product Description
Product Description
Amorphous transformer 400kVA brand EMC by Thu Duc Electro Mechanical Joint Stock Company is designed and tested according to TCVN 6306 standard (equivalent to IEC-60076).
Transformer manufacturing technology using Amorphous amorphous steel core brings outstanding features such as:
- Low loss: The no-load loss parameter of Amorphous transformer is 1/4 to 1/3 of that of a transformer using traditional electrical engineering steel (silicon tole).
- Reduced heat generation: The amount of heat generated during operation is lower, helping the transformer to operate more stably and efficiently.
- Reduce emissions: Because the machine uses electricity efficiently, it also limits the amount of CO2 emitted into the environment.
- Long life: Amorphous distribution transformers save operating costs for investors with a lifespan of up to 25-30 years.
Structure of Amorphous transformer 3 phase 400kVA
Amorphous EMC transformer is composed of 3 main parts: amorphous steel core, coil and fins – shell.
- Steel core, magnetic core: Low-loss transformer when applying Amorphous tole core processing technology, also known as amorphous steel core (ADMT) with high magnetism and resistance.
- Coil: Includes 2 windings, the primary coil has N1 turns and the secondary coil has N2 turns. State-of-the-art winding technology provides superior overvoltage tolerance.
- Casing fins: The housing is machined by corrugated steel, rigorously tested for tightness, cleaned by metal ball blasting and protected by powder coating for added durability.
According to customer requirements, EMC transformer housing can be hot-dip galvanized to meet installation requirements in saline areas.
