New Porcelain Strain Insulator


A new type of strain insulator, known as the Triangle porcelain strain insulator, has been placed on the market by the Illinois Electric Porcelain Company, Macomb, Ill. As shown by the accompanying illustration, its form is such as to give it an exceptionally large leakage distance; this is said to be 50 per cent greater than that of any porcelain strain insulator. It is claimed to be about 30 per cent lighter in weight. The material is so disposed that the body is nearly of the same thickness throughout. This insulator is also of such shape that in the process of molding the porcelain is made much more dense than in ordinary forms.
