East River Electric has been using these point switches for some time. I think Minnkota Power does as well (Central Power, on the other hand used KPFs).

Looks like they're using glass disks on new transmission construction?

Yup!

For some reason, it seems that disks have been getting popular again for a lot of transmission applications. Perhaps the polymer strains aren't as good as we thought?

Yes, I read an article recently that some companies are actually going back to disk insulators because there have been a few reports of polymer suspensions actually failing due to a corrana phenomenon called banding.

That's interesting. You think you'd be able to post a link to the article? I'd like to give it a read. Would be neat to see some failed polymer suspensions.
