We have been to Subotica to shopping trip before Xmas. Near the road I found fallen poles: oops.. I have foud 3 this like Insulators, they are a fuse socket pin type Insulators. They are common in Serbia, every 5th-6th low voltage poles have this like Insulators. The pins were cemented with epoxy or plastic-resin. Have some idea to remove them? I think, a pole-drill needs to bore (destroy) the metal pin. The 3td piece is broken, I glued it.
