CD 331, PYREX, Yellow Tint

CD 331, PYREX, Yellow Tint
A very large power insulator produced by the Corning Glass Works in Corning, New York for the Pyrex trademark line of insulators which produced insulators in the 1920's - 1940's.

The CD 331 Pyrex insulator with a width of 15" and height of 11" and weight of 38.25 lbs makes it the largest and heaviest glass pintype insulator produced in North America. This Pyrex insulator known as mold style No. 701 were produced in the 1930's and supported voltages of 70,000 volts.

Most CD 331s were used around Dalles & Pendleton, Oregon; Walla Walla & Dayton, Washington; Montana.

Here is a link showing them in service use. Photos by Bill Rohde.

Nice piece. Would like to have one someday but any that make it to a show are usually sold before they're on the table. Tommy Bolack has a BUNCH - I counted over 20 in and around his house!

Thanks! I rarely see them at shows because I guess people don't want to drag these big hulk of glass around. Sounds like Tommy needs to sell some out if he's got that many. They only come in three colors.

This is the new piece of glass I purchased so I could photograph all my power pieces individually. It was very difficult laying this big heavy insulator down on the glass, and man I was very nervous about it setting there on the glass even though it was thick glass.
