THE TRANSMISSION OF ELECTRIC POWER FROM NIAGARA FALLS TO BUFFALO.
IN NOVEMBER NEXT THE FIRST POWER WILL BE TRANSMITTED AND WILL BE USED BY THE BUFFALO RAILWAY COMPANY - A TRANMISSION LINE OF UNUSUAL IMPORTANCE - AN EXAMPLE OF FINE ENGINEERING.
For some time past there have been rumors that electric power was soon to be transmitted from the plant of the Niagara Falls Power Company, at Niagara Falls, N. Y., to be used in Buffalo, N. Y. It took some time to secure the proper right of way, and as the work involved was of an original and novel character, considerable time and thought was devoted to the consideration of the best means for carrying the current. A few weeks ago the Cataract Construction Company made a contract with the White-Crosby company, of 29 Broadway, New York city, for the complete design and construction of the transmission line. An unusual amount of special designing has been required, and this the White-Crosby company has carried out with its well known engineering ability and thoroughness. Mr. J. G. White has devoted his personal attention to the matter, and his efficient corps of assistants has rendered him worthy aid. Work will be commenced at once, and, when finished, the line will have cost in the neighborhood of $500,000. This is one of the most important electrical engineering contracts ever begun, and the reputation of the firm which has it in charge assures its success.
The accompanying drawings will give a very good idea of the appearance of one of the poles and its fixtures used in the line and of the special type of insulator employed. The poles are of round cedar, shaved and painted, with 9 and 10-inch tops. The length will vary from 35 to 50 feet, depending on the soil and the requirements of the line. The cross-arms are of hard, yellow pine, 4 inches, chamfered and painted. The short arm, shown in Fig. 1, is a standard six-pin electric light arm bored for two pins. This cross-arm will carry a private telephone line from the power house at Niagara Falls to the transformer station in the city of Buffalo. The cross-arm braces have been specially designed and possess several points of novelty. They are made of two and one-half by one-quarter inch angle iron, formed hot and bored for lag screws. The angles weigh about 20 pounds apiece and are primarily designed to act as trusses. As will be seen in the drawing, the bearing surfaces are on the under side of the cross-arm. The cross-arms are gained into the poles and are fastened with two lag screws staggered.
The pins shown on the extremities of the lower, long cross-arm are steel guards to prevent any of the conductors from falling in case a tie-wire, pin or insulator breaks. The long steel pins on the top cross-arm are for a similar purpose and also to carry the galvanized iron barbed fence wire, which will be used as a lightning conductor. Another conductor of the same kind will be carried on top of the poles. At every fifth pole these lightning conductors are grounded to a coil of wire buried at the foot of the pole.
Each conductor of the transmission line is of 350,000 circular mils stranded bare copper wire. When the line is completed there will be 12 of these conductors. Each pole will then carry a
