Insulators for High Potentials

The insulator shown herewith, made by the Lima Insulator Company, of Lima, N. Y., is intended for use on lines carrying electrical energy at pressures of 100,000 to 150,000 volts. They have been designed and patented by F. M. Locke for service above the 100,000-volt potential. They have been tested up to 300,000 volts with heavy spray without arcing and without showing the usual static stresses, and are approved as efficient by electrical engineers for this class of work. Mr. Locke has installed at Lima, N. Y., a 450,000-volt transformer of large capacity for the testing of these insulators intended for extremely high voltages upon which the Lima Company is concentrating its attention.
