Product Introduction
The 8 MVA oil Immersed transformer was made by us in 2017. the rated power of the transformer is 8000 KVA. It is three windings transformer, it has two output voltage. the primary voltage of the transformer is 33 KV, the secondary is 6.6 KV and 0.4 KV. This is three phase transformer, the cooling method is ONAN, Our 8 MVA 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 self-cooled type transformer?
Oil filled self-cooled type uses small and medium-sized distribution transformers. The assembled windings and core of such transformers are mounted in a welded, oil-tight steel tanks provided with a steel cover. The tank is filled with purified, high quality insulating oil as soon as the core is put back at its proper place. The oil helps in transferring the heat from the core and the windings to the case from where it is radiated out to the surroundings.
For smaller sized transformers the tanks are usually smooth surfaced, but for large size transformers a greater heat radiation area is needed, and that too without disturbing the cubical capacity of the tank. This is achieved by frequently corrugating the cases. Still larger sizes are provided with radiation or pipes.
FAQ
1. How soon can you delivery the transformer?
It depends on the quantity and capacity of the transformer, normally within one month since the date drawing confirmed by buyer.
2. How long can you provide the quality warranty?
12 months since the date transformer operated.
3. What payment method do you accept?
T/T (wire transfer), L/C both accepted.
