One of these feeders stops at the beginning of theextension, while the other is carried to the Newark endof the Oak Island viaduct. From this point a 500, cable is carried to the shipyard terminal. The feeders are tapped into the trolley wire every 500ft., and at each second tap a Westinghouse MP light-ning arrester is located. There is a similar arrester atthe point where the cables change from undergroundto overhead construction. The taps to the trolley aremade by using a copper span wire insulated from thepoles by strain insulators and connected at one end to. FIG. 13—SUPPORTING THE POLES ON THE STEEL VIADUCT the feeder and along the span to the trolley wiresby means of feed yokes. A better idea of the amount of copper required canbe gained from the statement that for the extensionalone 3200 ft. of 1,000, paper-insulated, lead-covered cable, 24,000 ft. of 1,000, triple-braid weatherproof cable and 4000 ft. of 500, weatherproof cable was required. To sup-ply the Gotthardt Street connecting link, a 300, aerial cable is carried along the track. Thisis connected into the existing feeder system, which hasbeen reinforced by a 500, cable running backto Newark substation. The feeders are supported onglass cable insulators mounted on locust stand-ard pins, except at the curves where composition in-sulators and iron pins are used. The rails are depended upon for the return circuitand are bonded with 8-in. No. 0000 gas weld bonds
