Product Introduction
The 12 MVA power transformer was manufactured by us in 2005, the rated power of the transformer is 12000 KVA. It’s a step-down transformer which convert 33kv to 11kv, the primary voltage is 33kv, the secondary voltage is 11kv. This transformer equipped with a on load tap changer to easy change the output voltage. Our 12 MVA power transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.
SCOTECH ensure each one of our delivered transformers had passed the full acceptance test and we remains 0 fault rate record for more than 10 years so far. Our oil immersed power transformer is designed in accordance with IEC, ANSI and other major international standards.

What is oil filled water cooled type transformer?
This type is used for much more economic construction of large transformers, as the above-told self-cooled method is very expensive. The same method is used here as well- the windings and the core are immersed in the oil. The only difference is that a cooling coil is mounted near the surface of the oil, through which cold water keeps circulating. This water carries the heat from the device. This design is usually implemented on transformers that are used in high voltage transmission lines. The biggest advantage of such a design is that such transformers do not require housing other than their own. This reduces the costs by a huge amount. Another advantage is that the maintenance and inspection of this type is only needed once or twice in a year.
