Thx Stephen. I am using Berkshire Valley and San Juan Car Co. insulators, Keil Line (now Scale City) transformers and spool insulators, and sometimes Keil or BV lampshades. I have some Wiseman parts that are very similar to PSC that I used on other poles. BV makes some smaller transformers that are pretty nice too. Someday I will model those square transformers that are still common in Pittsburgh. I wish there were more detail parts for utility pole modeling such as larger insulators.
Here's a neat photo gallery of Duquesne Light poles:
