Cable Sheathing Task Troup of the Technical Steering Committee In June, 1955, a committee consisting of A. A. Smith, Jr. - American Smeltin'; 4 Refining Co. T. M. Bcuton-------- Bell Telephone Laboratories T. T. Isbell - -- - St. Joseph Lead Co. C. J. Snyder ----- Anaconda Tire & Cable Co. R. J. Wiseman ------ The (Aconite Co. was appointed t>7 the Technical Steering Ccmittee of the Lead Industries Associa tion to study the use of lead In cable sheathing and to make suggestions as to posslblo Improvements that could be made either In the alloys used or manufacturing methods. Later Itr. E. J. Uerrell of Phelps Dodge Copper Products Corp. was added to the Cccrdttee. Three meetings of the Ccmittee have been bald, and the tentative conclusions reached weret 1. that the power cable industry would like to see a better alloy than is currently being used, whether it be for continuous or intermittent extrusion, and 2. that both the power and coomunications cable industries would be interested in lead alloys with ccnparable proper ties to those they are now using on Intermittent extrusion for continuous extrusion. After considerable discussions it was felt that the development of a new alloy with greatly improved properties offered snail chance of success considering the large amount of work that has been done over a period of many years. However, this possibility should not be entirely overlooked, and tbo Committee will keep it in mind. It was suggested that a co-operative research program on continuous extrusion be considered with Plrelli-Hilan aid Lead Industries Association contact them with regard to power cable sheathing and to go as far as to offer them sufficient copper bearing and arsenical lead alloys for their experimental work. Hr. Bcutoo offered to contact; them independently with respect to ljf antioonial lead caanunicatlons cable sheathing alloy.
