The production technology line for transformers in Vietnam

The production technology line for transformers in Vietnam:

Vintec Group has invested in modern transformer manufacturing technology, with most production machinery and key input materials imported from European countries.

Vintec transformers are designed, manufactured, and tested according to quality standards ISO 9001 – 2015, ISO 14001, TCVN 6306, ANSI…

Vintec transformers are made from various materials imported from industrially developed countries such as France, Germany, Italy, Japan, and South Korea…

Vintec directly imports the Gorge automatic sheet metal cutting line from Germany.

Low Voltage Coils: Made of copper foil to reduce short-circuit losses and eliminate axial forces, ensuring transformer safety during short circuits.

High Voltage Coils: Wound in layers, evenly distributing voltage under overloads or faults. Insulation layers consist of a special paper with high mechanical strength, heat resistance, and dielectric properties. Additionally, adhesive layers between winding layers prevent vibration and axial forces during transformer operation and short circuits.

The core assembly process is performed on an assembly line and checked at each stage. After placing the steel core on the assembly bench, coils are mounted onto the core. After checking insulation parts and centering, clamps are installed using bolt clips.

Output terminals are adjusted and wrapped with special insulation paper, with positioning and separation sheets to avoid confusion. Low voltage terminals are securely clamped with bolts using connecting lugs or porcelain caps.

All Vintec products undergo strict quality control processes from raw material sourcing to final product testing, ensuring compliance with international standards such as IEC-76, ANSI, TCVN 6306.
