Aluminum Transmission Lines. ANON. (Eng. , xcv, No. 2455, 86.)--The British Aluminum Company, Limited, of lO 9 Queen Victoria Street, London, E. C., has published a pamphlet dealing in considerable detail with the use of aluminum for overhead electric transmission lines. It states the general conditions, determines the design of transmission lines, gives a large amount of technical information for both copper and aluminum, from the transmission line point of view, and makes out a strong case for aluminum. This information covers comparative figures for conductivity, weight, tensile strength, temperature resistance effect, and expansion coefficients for the two materials. Questions of deflection and stress, jointing, the losses on lines, etc., are also dealt with, and the official standards for overhead line construction of various countries are given. This work should be consulted by all concerned with actual or projected overhead transmission work.
