Middle of 1960xx. Sealed bushings

In mid 1960-s, an important event happened at Izolyator Plant – а hermetic bushing was developed. At the same time, due to the order for bushing development and manufacturing for Aswan dam in Egypt, a reversible sole batch furnace was commissioned for large porcelain product baking (with the height of up to 5 m). This allowed the plant not only to fulfill this important order, but also to begin serial production of the high voltage oil-filled bushings.
