Insulator
The Hemingray 45-T insulator is a double petticoat, extra tough glass insulator. The glass in this rugged insulator is tempered to provide resistance to pellet and rifle damage and thermal shock. It is recommended for use in areas where circumstances or conditions require a dependable, heavy-duty insulator. Specifications of the 45-T conform with all specifications established for communications insulators.
Because of its tough glass surface “skin” it can be tightened more securely to the arm pin without fear of breakage. Its resistance to torque and transverse pull means that the pin would shear off before the insulator could break. Insulator trouble locations in the field can be spotted quickly because, if broken by causes beyond normal use, the insulator disintegrates into small, nonsharp fragments. It cannot crack nor be punctured. Owens-Illinois, Dept. RSC, Toledo, Ohio.
