With this demand in mind, the Locke Insulator Manufacturing Company, of Victor, N. Y., has brought out its No. 601 strain insulator, illustrated, which is 6 ins. high and 5 3/4 ins. in diameter, designed for voltages up to 8000. The company has also developed a smaller design strain insulator for voltages of s000 and under, and finds that it is very useful in the construction of spans for trolley suspension; in fact, this latter type has proved to be valuable in more places than the manufacturer a
