They're now putting up the monopoles on the east end of the 115kV loop now - it's not clear, but the new pole is right between the two circuits and will likely be changed over after the H-frames just west are replaced. It seems they are using polymer strings after all, with glass likely intended for the corners and switch poles.

They should use disk strings on all the poles. I don't trust those rubber chicken insulators. Connecticut Light & Power's gone back to using disk strings on their new 115kV lines (brown ones too as an added bonus), along with a few other utilities I've seen. The disks seem to do better as suspension insulators than the polymer chicken sticks it seems.

Why they are called "chicken" insulators?

Because of how thin they look compared to strings of glass or porcelain disks, the polymer insulators are compared to the "rubber chicken" gag item.

The old pole is now gone and this section of the rebuild is completed.
