Insulator produced by Ginori in November of 1928 for voltages below 50kV. The insulator is composed of two ceramic parts fixed with a very resistant metal band that served to avoid the expansion of the cement (Galvano's patent of 1921 for railway use). The capsule is made of cast iron fixed with cement and two cords of asbestos around to avoid the expansion of cement (Ginori's patent of the '20s). This is an experimental model very reinforced and designed to install on difficult and stressful points of the line, so far only four specimens are known. Rescued with my friends Christian, Marco and Guido.
