Discussion on “a distribution system for power purposes” (Nims), Spokane, Wash., September 10, 1914. (see proceedings for August, 1914)

J. B. Fisken: It was my good fortune last year at the Pacific Coast Convention to Vancouver to see quite a good deal of the work that Mr. Nims had done with this ductless cable. I have noted some of the points on which I would like to hear some discussion. These are: the relative cost of ductless and duct lines, the use of the various insulations, such as paper, varnished cambric, and rubber and the relative advantages of the wire of the shape he mentions as against round wire; I also ask Mr. Nims in replying to state if he knows what is meant by lead cable costing $606 a thousand feet to which he referred. It appears to me that this system of ductless underground cable is eminently suitable for distribution in residential districts, but I don´t see how it can be practicable in congested districts such as the business part of the various cities where you might have as many as thirty or forty cables in one duct line; it would appear to me that there would be many operating difficulties — or, rather, maintenance difficulties in keeping such a layout as that in commission.
