Glass Insulators in use


Probably 90% of all glass insulators still in use are on the railroads.


Pyrex carnival glass suspension insulators in use in Eugene, Oregon.


Bowl-shaped suspension insulators can be found in Southern Oregon. This is in Grants Pass right along interstate 5.


Detail of the insulators. I have some in clear. There is no manufacturer listed on them.


Here are some more blues by Lost Creek Lake, NE of Medford.


Hemingray High Voltage No. 4 still on a pole?


Here are some in Mexico, on the highway to Puerto Peñasco.


Here's a detail of the Mexican suspensions.


Here's some glass still in use to power a sign at Jackson Hot Springs in Ashland, Oregon. Jackson Hot Springs has been open since at least the turn of the century.


There are 3 McLaughlin CD154's here, and I'm not sure what the other one is.


This is near Wickenburg, Arizona. I've seen these just west of Coolidge, too.


It looks like a CD238/CD239 or similar.


Here's a "Lightning Stool" as used in fire lookouts. It's a remainder from the crank telephone years. If a thunderstorm was near your lookout and you needed to report a fire, you would stand on the stool before touching the telephone to avoid getting shocked by the static buildup on the lines. They are still in use in many lookouts, although most report fires by radio now.


Here's a Pyrex CD331 in use in Arizona. It's protected by 69,000 volts!


There's still alot of glass up in the air - this is on Rte 66 near Seligman, AZ.


These toll lines are near Susanville, CA and Reno NV. I would guess that there are over 15,000 insulators in the 20-mile stretch I saw by the road.


750KV DC line built in 1970 from the Columbia river to Los Angeles. Glass suspension insulators new in 1970!


CD221's in use along Route 66 in Arizona.


Here's one side of an antenna I have installed at my shop. Its a Hemi 42 on the pole. Note the green glass antenna insulator too.
