BUSINESS. · · Its insulator record on the heavy transmission lines from Niagara Falls to Buffalo is one of which the Imperial Porcelain Works of Trenton, N. J., is justly proud. The special insulators used weigh nearly 12 punds each. They were subjected to severe tests. Each one was immersed in a salt water bath and a current of 40,000 volts from a transformer was used. At the slightest sign of a defect of any kind, the insulator showing it was at once condemned. Although such a test may appear unusually severe for insulators designed to carry a circuit transmitting but 10,000 volts, it was deemed to be the wisest course to pursue, as it assured a large factor of safety. Porcelain insulators from three concerns were tested. It is but just to state that those manufactured by the Imperial Porcelain Works of Trenton, N. J., passed the severe test with an unusually high record. Less than two-thirds of one per cent. of one pattern of the insulators supplied by this firm failed to stand the test. · ·
