All Vintec products are fully tested in a standard testing room before being shipped. Ensuring stable quality and creating absolute peace of mind for customers.
Vintec’s set of quality indicators
A special thing about this transformer is that in addition to meeting the general standards of transformers according to IEC International standards. Our Vintec transformers still fully meet the standards of the domestic electricity industry such as: QD62/EVN; Decision 2608/SPC; Decision 3079/CPC; Decision 1011/NPC; 8525:2015…
4. Characteristics of open-type three-phase oil transformer with capacity of 3000kVA:
4.1. Transformer core:
– The core is made from Silicon steel with good magnetic conductivity and high oxidation resistance. The machine’s steel core is made from many very thin steel sheets with a thickness of 0.3 – 0.5mm. The outer surface has insulating paint and is coupled together into a closed loop circuit. The purpose of joining thin steel sheets together is to reduce energy loss that occurs during machine operation due to Foucault eddy currents.
– The silicon steel used by Vintec is imported directly from Nippon Steel, Japan.
Silicon corrugated iron produces the core of 3000kVA open-type 3-phase oil transformer.
4.2. Transformer winding.
– The winding consists of a primary coil and a secondary coil with an excellent design structure that helps the machine operate effectively. The machine core is manufactured from EI/AIW enameled copper wire (220oC) meeting IEC 60851, JSI C 3202-1994 standards. Ensure technical indicators such as flexibility, adhesion, electrical strength, elongation, elasticity and transformer oil resistance to help reduce Foucault eddy currents during operation.

6. Experiment on Transformer 3000kVA
Testing transformers in the production process is one of the mandatory steps and is complied with strict requirements in current Electricity testing regulations, and is also a process to achieve
7. Storage and transportation of open-type transformers
Policy on transporting and preserving transformers before connecting to the grid system. Vintec always supports customers with transportation as well as instructions on proper product preservation procedures to ensure the product has the best quality when used.
7.1. Preserving the transformer:
When the machine is not in use, keep it in a dry place. Protects porcelain clusters, avoiding collisions that can crack, break, or chip porcelain. It is best to keep it in a covered warehouse. The transformers must not be placed too close to each other to avoid damaging heat sinks and other attached equipment.
7.2. Transporting the transformer:
It is necessary to keep the transformer straight and absolutely not tilt it. It is necessary to tie it firmly so that the machine does not move during transportation. Do not tie it to the corrugated radiator fins or ceramic insulators.
When transporting by car, Vintec’s transport always runs at a speed of no more than 30km/h.
