Locke insulators for Washington Water Power Co.

THE LOCKE INSULATOR MANUFACTURING COMPANY, Victor, N. Y., Is calling attention to the satisfactory service of its insulators on the 60,000-volt line of the Washington Water Power Company, for which it furnished 33,500 "Victor" insulators, by the publication of a facsimile of a letter sent by the power company to the Electrical Testing Laboratories, New York city, commenting upon the inspection and test of the latter of the insulators involved, only one of which failed, by puncture, since the fall of 1903.
