  1. Thank you very much people! Bill Kibbel I'll follow up on that site you gave - I've got it bookmarked - and see if the folks there are able to shed more light. Have a great weekend everyone.
  2. Thanks Mark: Not stacked, as there is a thread in the center for fixing to a power pole. I based my guess on voltage on the modern example on the power line outside our home (subdivision developed in the late 1990s) This pic is of one of three identical lines on cross trees on the power pole.

  3. You folks have proved very helpful in the past with my Museum Research questions, and I'm back with another. I'm currently researching and cataloguing this screw type multi-skirt power line pole insulator. (Please correct my terminology, BTW, as I'm making up my own terms out of ignorance of the correct ones.) Could you please tell me the Voltage Range for an insulator such as this (My guess = 30-40KV) and the date (I know the screw base was discontinued, but don't know the time-frame.) Many thanks for consideration.
  4. Les, that's indeed an interesting prospect. If you are so inclined, just one "Tube" would complement our two item collection. If you happen to have any provenance to accompany the tube you select, so much the better. (Age, Manufacturer, Location the tube was used in, that sort of thing.) We have very little available display space - these insulators sit on a shelf in our Museum Promo section next to the Visitor Information Centre. That section is house din what used to be a broom closet - so you maybe get the idea! If this Forum does Private Messages, PM me and we can push this forward. Do
  5. LOL - stuck in the joists I expect! If I ever get access tot hat buildnig again I'll take a look - now I know what I'm looking for. Thank you all for this excellent information.
  6. thanks, and I'll read that .pdf later - it's lunch here now LOL
  7. Bingo! That looks like the solution - and thanks for the Manufacturer info as well. May i quote you in my "Narrative" for these insulators?
  8. Thanks, but the tubes look longer and thinner that our insulators, and the squat ones you show are two piece, while ours are one piece. Any thoughts?
  9. Thanks, but these are one-piece, there's no detachable top with which to clamp the wire. Interesting photo though, do you mind if I use it when writing up the "Narrative" for these insulators?
  10. Hi, I've a question on the use of insulators we have in our museum's collection. We have two. These are small white ceramic, with a hole in the top presumably for accommodating a fixing nail. Both have U.S.A on the top together with similar, but not identical makers marks.WIS-P AND WIS-P-C Here's a couple of photos: and the underside: Any help you could give me in identifying the system these were used for would be helpful. They were recovered in 2003 from the inside of a building that had been a pool hall among other things in the village of Sheet Harbour, Nova Scot
