BETTER GLASS FOR INSULATORS
MANY years of painstaking research and costly experiments finally resulted in the perfection of an improved glass for power line insulation purposes. This glass is better suited to the manufacture of electrical insulators than other types previously used. It is tougher and less affected by sudden temperature changes. It possesses high dielectric strength, does not age and is non-porous.
Insulators made of this improved new Hemingray glass will perform better in actual service. The entire Hemingray line of distribution line insulators has been redesigned. Extra strength has been built in sharp corners were eliminated, careful consideration was given to proper shape and thickness of petticoats and the distribution of mass in the body of each type of insulator. These new design features coupled with a stronger and more adaptable glass, make these insulators unusually economical and highly efficient for distribution line service.
SPECIAL FEATURES OF GLASS
Hemingray insulators, in general, possess the following inherent advantages:
TRANSPARENCY -- Exposes internal defects.
HOMOGENEITY -- Insures uniform insulating properties throughout each insulator.
NON-POROSITY -- Eliminates moisture absorption. Sustains dielectric strength. Prevents deterioration. Easy to inspect. Unaffected by time or elements.
