Display of my Glass Power Insulators

Display of my Glass Power Insulators
This is a display cabinet of my glass pintype power insulators. These insulators were used for high voltage distribution and are the largest and heaviest glass pintype insulators produced in North America. Take insulator CD 331 which is 15" wide and 11" high and weighs in at 38 lbs, which makes it the largest and heaviest glass pintype insulator produced in North America. This Pyrex insulator was produced by the Corning Glass Works in Corning, New York in the 1930's and supported voltages of 70,000 volts. One of the more unique insulators which is really not a power insulator is the CD 317 Chambers Lightning Rod Insulator. This insulator was produced by the Hemingray Glass Company in Covington, Kentucky from c1877-1880's which were used on lightning rod systems.

Some of these sure would have been neat to see in the air!

The only one that kinda stands out is that Chambers - since it was more for lightning protection than power. :)

That's a nice collection you have there! Those 70kV-class Pyrex Insulators sure are big, aren't they? If I recall, there were some in use in the state of Washington.

Thanks for pointing that out about the Chambers! I added that info to my caption.

Thanks! You are right, a lot of the CD 331s were used around the Walla Walla and Dayton, Washington area and throughout the southeastern part of the state. Also used in Oregon and in smaller numbers in Montana.
