The circular millage of the wiresanchored here is therefore 10,182,000. Fig. 5 is from arecent photograph of the terminal. Trunk line No. 3is carried similarly. In order to secure reliable and handy electrical con-nection for the large cables, as well as to properly insu-late them, a number of special devices were set of samples of those principally used is shown inFig. 6. Nearly all the copper in the trunk lines is ofthe 500,000 circ. mils size, and for dead-heading it and. was devised. It is of tough brass, and the body of it istapered so that the end of the cable may be spread openbefore the solder is sweated in, thus making a con-nection which it is practically impossible to break. Asocket is formed on one side of the connector, with set-screws, to receive the jumper, which connects thedead-ended cable with the bus-bar on the junctionframe. This socket and the body of the connector aretinned before using. The eye of the connector is pinnedby a ^8-inch bolt to a brass yoke, A, a pair of whichare used to yoke together two Johns giant straininsulators. The other yoke is pinned to the eye-bolt inthe junction frame. This combination forms a conven-ient connection of remarkable strength. None of theseveral hundred in use have ever been known to giveaway. The pieces marked B, C and D, also of brass,are known as clamp T-connectors. They are used toclamp on the 500,000 circ. mils bus-bars, to receive thejumpers from the dead-ended cables, a
