Properties of lead and lead-alloy cable sheaths
14 July 1934
In recent years a large amount of work has been carried out in developing new lead alloys for cable sheathing purposes, and the author gives a list of metallic sheathing materials which have been proposed or used. The different qualities that the sheathing material should possess according to the kind of cable to which it is to be applied (telephone or power cables and laid in ducts or otherwise) are also tabulated. Previous work on the properties of cable sheathing materials is briefly reviewed, and some special tests made by the author are then described. These tests relate to age hardening, fatigue-strength, tensile properties, creep, corrosion, etc., and the methods and machines used for the tests are explained with the help of further tables and curves. A comprehensive list of references to the works of other investigators of the subject concludes the article.
