Of the converters the 2000-kw. machineis a new one purchased from the Westinghouse Electric& Manufacturing Company, and the others are second-hand machines brought from other substations whererecently increased power demands have required theinstallation of larger machines. The increased traffic has also necessitated some ad-ditions to the companys Fifty-Eight Street and Wood-land Avenue substation, a 1500-kw. converter recentlyremoved from another substation having been installedhere. To gain increased primary power capacity atthis substation a No. 0000, 13,200-volt paper-insulated,lead-covered underground cable has been run from theThirty-Third and Market Street power house of thecompany to the substation. Structural Details of the New Substation A general idea of the structural details of the newsubstation can be gained from the accompanying illus-. FIG. 11—SUBSTATION UNDER CONSTRUCTION, SHOWINGTRUCK ENTRANCE AND CRANE SUPPORT trations. The photograph from which Fig. 11 wasreproduced was taken from Eightieth Street. The open-ing in the lower left-hand corner is of sufficient sizeto permit a truck loaded with the larger portions of aconverter or transformer to be backed into place withinreach of the overhead crane. One of the supports ofthe crane track can be seen through the window open-ings. In Fig. 12 is shown the conduit for the low-voltage circuits just preparatory to pouring the concretefor the main floor. The crane girder with the detailscf its support are also well shown in this view of the substation structure in process ofconstruction showing the foundation for the outdoorsubstation, and one of the roof trusses of the convertersubstation is illustrated in Fig. 13.
