Locke Insulator Manufacturing Company, Victor, New York

Pin Type Insulator

The Locke Insulator Manufacturing Company of Victor, N. Y., now manufactures ten designs of pin-type insulators for voltages ranging from 27,000 to 80,000. Several designs are offered as new types for their rated voltages. In these units it is claimed that the electrical and mechanical characteristics provide an ample factor of safety for the most severe requirements. In the accompanying illustration is shown an insulator that has a line voltage rating of 50,000 volts. The dry arc over voltage is 175,000, the wet arc over voltage is 120,000 and the leakage distance is 23.5 in. The mechanical strength is 5000 lb.

Insulator Rated at 50,000 Volts.
