Shot of the other side of the pole. When I was working in the Yreka, California service area six years ago these CD 220 Hemingray small power glass were mostly the small wire groove variants and there were some of the blue tinted ones still in service. The blue tinted ones are absolutely awesome to view on a good sunny day. Glass power insulators in service are disappearing at an alarming rate so if you can photograph any in your area get to it before its all polymer and yuk!
