Product Introduction
This 90 MVA power oil immersed transformer was manufactured by us in 2014, the rated power of the transformer is 90000 KVA. This 90000 KVA Step Down transformer 220kv to 33kv, the primary voltage is 220kv, the secondary voltage is 35kv. 220kv low-loss series transformer is our independently developed new generation of transformers based on absorption of domestic and foreign advanced technology, which feature low local discharge, low loss, low noise, high reliability, strange protection against abrupt short circuit. Our 90 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, oil immersed power transformer is designed in accordance with IEC, ANSI and other major international standards.

What is the difference between dry type transformer and oil?
The biggest difference between oil-immersed transformer and dry-type transformer is that there is no “oil”. Since oil is liquid and has fluidity, oil-immersed transformer must have a shell. The inside of the shell is transformer oil. The dry type transformer has no oil, so the outer shell is not used, and the coil of the transformer can be seen directly.
