Electrose High-Tension Insulators.
In a paper on the electrical plant of the Canadian Niagara Power Company, presented before the recent annual convention of the Canadian Electrical Association, Mr. Harold W. Buck, chief electrical engineer of the Canadian Niagara Power Company, formerly electrical director of the Niagara Falls Power Company, gave a description of the insulator used on the transmission line to Fort Erie, which line will supply current to Buffalo. The length of the line, which is of 37-strand aluminum of 500,000 cir. mils section, is 15 miles, the voltage being 24,000.
The material of the insulator, which is shown in the accompanying engraving and made by Electrose Manufacturing Company, 127 North Tenth Street, Brooklyn, is "Electrose," an insulating compound which has been largely used in telephone, telegraph and electric railway work, and is now being employed for all forms of high-tension insulation. Mr. Buck states that this material is a very good insulator, is very strong mechanically and is entirely free from cracks and other defects which are common in glass and porcelain. Similar insulators have been used on the Buffalo transmission lines of the Niagara Falls Power Company for the past three years, and they are the only insulators on those lines which have caused no trouble. Mr. Buck adds that it is impossible to shatter Electrose insulators by stone throwing, and they will frequently turn a rifle bullet without being damaged seriously.
