Attached are (4) Transformer related drawings, compiled a few years ago (via AutoCAD).
While searching through some Archives, I came across a whole bunch of CAD Drawings that never got exported &/or converted to a Graphical Image File Format.

These Four Images were hiding with the other CAD Drawings.
Drawings were 'Rasterized" last night (Saturday, January 23rd 2010) and uploaded to ECN on Sunday, January 24th 2010.
More Drawings to follow later this week;... possibly next week / month / season / ...
