MBT's transformer manufacturing process
MBT has invested in modern transformer manufacturing technology, most production machinery and testing equipment as well as important input materials are imported from G7 developed countries. This article will show you the transformer process to help you understand how we can produce a high-quality transformer.
I. Applicable standards
II. Transformer materials
MBT transformers are made from materials imported from G7 countries such as France, Germany, Italy, Japan,...
III. MBT's transformer manufacturing process
How to manufacture MBT transformer?
The manufacturing process of MBT transformer
1. Coil slitting machine
BOLLINA automatic sheet cutting machine line is imported directly from ITALIA by MBT
2. The coil cutting machine
Magnetic circuit steel sheet is made by cutting technology, continuous cross-cut, assembled with high precision. Thus, no-load loss, no-load current and noise are reduced during operation.

3. Automatic wing folding and sealing line
4. Laser cutting machine
LASER TRUMPF cutter imported from GERMANY
5. AMADA punching machine
AMADA punching machine imported from JAPAN
6. TruBend 5170 folding machine
TruBend 5170 folding machine imported from GERMANY
7. Low voltage, high voltage winding machine
Low-voltage winding: The transformers with low-voltage winding are made of copper foil to reduce short-circuit losses and eliminate axial force and ensure the transformer's safety during short-circuit.
Low voltage winding machine imported from ITALIA
High voltage coil wrapped in layers, evenly distributed voltage when there is overvoltage or lightning. The layers are insulated with a special paper with high mechanical strength, heat resistance and high electrical insulation. In addition, there is an adhesive layer between the rings to prevent vibration and axial force during the transformer working and short circuit.

8. Install the machine's gut
The assembly process of the transformer gut is carried out in line and checked on each stage. After the steel core is placed on the mounting base, install the coils on the post. After checking the insulation and centering parts, install the top beam with bolt clamps.
The output terminals are adjustable and covered with special insulating paper, positioning paper, and separation of wires to avoid confusion. The low-voltage terminals are fastened by bolts with connecting stakes or porcelain.
9. Vacuum drying system
10. Complete assembly
11. Vacuum oil filling chamber
12. Powder coating line
13. KCS laboratory
All MBT products undergo strict quality control at all stages from input material to output product testing, ensuring that every product meets stringent requirements, according to international standards: IEC-76, ANSI, TCVN 6306.
Independent laboratory meets Vilas standard 1113- ISO 17025 2017
Continuing the mission in the context of regional and world integration, with the impact of the industrial revolution 4.0, the tradition of innovation and innovation focusing on quality, MBT always launches a line of high quality transformers and perfect value-added services. Apply information technology in the management and operation of transformers, bring practical values to customers and the society, and contribute to the development of a modern and sustainable Vietnam electricity industry.
