ID Insulators ?

[Steve J]

Hi - first post.
I recently bought a job lot of electrics and these 2 insulators were included.
They're not something I know anything about - can anyone tell me anything about them ?
I have no idea if they are electricity pylon type thing or telegraphy related ??
Both are Made In England.
Thanks

Hi _ Thanks for the reply. Bushings ? Are they not insulators then ?

They are insulators yes. Idk that much about them. I saw glass ones selling recently on icon. Pretty cool looking.

I believe those are for high voltage transmission lines.
