Abstract
THE successful transmission of thousands of electrical horse-power by overhead wires over hundreds of miles is not only feasible, but has also been proved in almost every country to be attractive from the commercial point of view. Satisfactory operation has been attained by the continual attention that electrical engineers have been paying to the technique of design, and to the improvement of the quality of the materials used in construction. Continuous laboratory research and long experience have enabled them to anticipate operating difficulties, and combat them by selecting suitable materials and altering the design so as to raise the factor of safety. Of recent years long reports, papers, arid patent specifications have been issued almost daily, and there are few who have the ability and the time to separate the grain from the chaff. This volume describes the latest constructional details, and makes references to the latest specifications issued by the British Engineering Standards Association, the American National Electric Light Association, and the Verband Deutscher Elektrotechniker. References are also given to many important papers published in the transactions of scientific institutions both at home and abroad. Novel data in connexion with steel cored aluminium conductors are given. These conductors are being extensively used, and necessitate changes in the details of transmission line design. This book can be recommended to both the practical and the academic engineer. The latter will see how many theorems given in examination papers have been modified to make them useful in practice.
