3.5 MVA 33/0.4KV Transformer Core
Transformer Core
Transformer core is the main part of magnetic circuit in transformer. It is usually made of hot rolled or cold rolled silicon steel with high silicon content and insulating paint on the surface. The iron core and the coil wound on it constitute a complete electromagnetic induction system. The amount of power transmitted by a power transformer depends on the material and cross-sectional area of the core.

FAQ
1. Where is your main market?
We had exported our transformers to more than 30 countries in the world, our main market is Africa countries, South and North American countries, and Asia countries.
2. What certificate do you have?
We have KEMA, CESI, CTQC type test report for our transformers.
3. How long is your delivery time?
30 days after drawing confirmed by buyer for distribution transformers below 5000kva, bigger transformers depend on the capacity and components, normally 30-90days(with imported components)
