Construction of the Hungarian open wire telephone network. This is German style, but it is a little bit different than the German one. We use J pins direct the under pins on 4 pins crossarm only. In Germany, Austria, Ex-Yugoslavia, Poland, Greece is similar German technology, in Czech rep. and Slovakia is a little bit different technology, they use 2 or 4 pins side arms. In Italy were mixed the porcelain and glass Insulators, France has an own interesting stye,
there is different constuction too. In Romania is American one.
Unfortunatery I don't know the other ones in Europe but each counties each constructions. In Ex-Germany, and Austria-Hungary's area are similar constuctions. But the only Hungarian construction are the Napoleon Hat terminal Insulator, the "Empty Upper Crossarm" terminal pole constuction with tin channel for porcelain rings, and the studded 2 pins side arm.
