right now there isn't a way to create or visualize electric wires in AIW so far. So you need to take a workaround.
I had a similar usecase where i needed to bring in some wires as a new planning. You simply safe the utility design work as dwg file and import it as pipelines into AIW. Make sure you create a proper "wire" style out of the exisitng pipeline styles.
In my case i had a civil drawing and exported the horizontal wires seperatly from the poles as sdf file and brought it in AIW as described above. the pole.sdf I inserted as pipeline connectors. This is more of a very simple workaround if you do not have proper poles models.
