For explaining the operation of the transformer Low voltage winding (LV winding) and High voltage winding (HV winding) are wound on different limbs of the transformer for easy explanation. However in practical each limbs of the core will have both LV winding and HV winding wound together.
In Transformer design LV winding will be wound close to the core of the transformer because the insulation provided between the LV winding and core of the transformer is quite less compared to the insulation provided between the HV winding and the core of the transformer which results in less cost for insulation and reduction in the size of the transformer for same MVA rating. Hence due to this reason LV winding is placed near to the core of the transformer.
On the core of the transformer insulation is placed and LV winding is wound. Once again insulation is placed between the LV winding and HV winding.

Thanks a lot!
Thanks
The language of the answer is very simple so that I can understand easyly ...Thank you.
Answer is satisfactory
Low voltage means high current .which means that the size of conductor will be more..and when the size is large ..u need large insulation ..so what is the cause for lv winding to be closer to the core...
Just curious, is that set up true to both step up and step down transformers? I have read that when winding near the core is used to excite the transformer, higher inrush current will occur compared when you used the winding far from core as exciter.
Kindly help me with this please.
