T. C. White Co. has new design of strain insulator

T. C. White Company, St. Louis, Mo., has just placed on the market a new design of porcelain strain insulator. This new type is intended for use on high-voltage lines. It is almost square in shape, and thus the distance between the grooves through which the cables pass is greater than in any other shape and the leakage surface is correspondingly effective. In this new insulator the unglazed surface, so common at one end of ordinary porcelain insulators, has been eliminated.
