This insulator was recovered by me after a wicked electrical storm. The pole that this insy was on got damaged by its blown transformer. It was taken down and replaced. most of the hardware and insies were left right on site. The pole one span from this one had a tree split by lightning, leaning heavily, breaking insies, crossarms and pushing all the wires together. This one was likewise taken down, but everything was "F" ed. This insulator has two "path to ground" electrical heat marks etched nicely.
