Title: Pole with old equipment and CBT
Post by: craigski on February 10, 2023, 12:15:27 PM

Noticed a local pole had CBT installed about a year ago, but puzzled what the old equipment on top of pole is, looks like old insulators for old GPO telephone wires?

Any ideas when these would have been used, 50+ years ago maybe? Must be an old pole.

An odd place to put the insulators, but yes they would have been used for 40lb cc conductors. They would normally have been fixed to cross-arms or a circular bracket around the pole to distribute the pairs. Open copper wires were still used well into the seventies, if not later, in rural areas. I remember the first drop wire being introduced in the mid sixties.

Circular bracket for mounting insulators at a DP.
Cross arm DP

I have noticed that some heritage railways still have them along the sides of the tracks and still use them.  :)

Have noticed the modern railway had a lot of line cabling just sat on the ground.  I assume this is down to copper thefts and quick temporary replacements ending up being permanent solutions?
