138,000 volts..

That's where the eagles sit cleaning themselves and surveying the area,sun rise..one on the left.




Insulators up there..




Base of pole..




Oh ya..mom was up there too,



Interesting stuff about them.

Sure is a great vantage point for an eagle. I sell the hydraulic torque wrenches that torque those big bolts up good and tight.

That might be 345 KV

How many ft./lb. are they torqued?

I based it on this.

Is there a good way to guess the power line voltage based on the number of insulator discs that attach the line to the transmission tower?
​

We usually use as a rule of thumb for determining the number of porcelain/glass suspension disc insulators: 10kV for each disc (standard 5-1/4' x 10").
For typical system voltages in North America, this would be:
69kV: 4-6 discs; 115kV: 7-9 discs; 138kV: 8-10 discs; 230kV: 12 discs; 345kV: 18 discs; 500kV: 24 discs.

I'm not sure that still holds true for todays newer dielectric materials. i was guessing on the knowledge that most transmissions lines in CT and Mass are 115KV or 345KV. 138KV might be used for an old factory feed like the old Stanley Company line from the Connecticut river to New Britain, CT was 138KV. Interesting....

No clue on those big power line poles. We've only sold a couple of those wrenches and we have one to rent, unless it's​ been sold?. I've only dealt with some contractors who were building a large steel shaft headframe and all large nuts and bolts had to be torqued really tight. I went to Eaton, PA for sales training on the tools maybe 6 or 7 years ago.

The tower footing bolts have a lot of variables like tension for example. A ballpark torque on a 1 3/4" bolt galvanized depending on the bolt ASTM class would probably be around 1000 Ft Lbs. Depends whether the bolt is inserted dry or waxed. If the threads are waxed then maybe 700 Ft Lbs.
