Possibility of use of silver plated copper wire in distribution transformer [India] 

++++

I would like to use silver plated copper wire in the distribution transformer. It shall reduce the size of the transformer and the cost correspondingly. I would like to know if there is a possibility of putting this idea to practice and what is the procedure to make such a wire. The Wire shall covered be electrically insulated kraft paper and subjected to a voltage of 11000 Volts and shall be immersed in Transformer oil for cooling and providing electrical insulation. The problem shall be whether the siler plating will wear off in the oil and secondly whether it will peel off during the manufacture of transformer coil.

It will not peel off, and I wouldn't expect it to wear off. But certainly you can buy silver plated wire without having to install an electroplating plant and learning how to electroplate?
