An unusual feature of the work is the use of steel cable forthe conductors. Each leg of the three-phase circuit consistsof a seven-strand, 7-16-in., plow-steel cable. Each cable isstrung in one length from the terminal at the sub-station tothe terminal at the city line. Steel was used in these cablesin place of copper or aluminum, primarily for greater average span is approximately 240 ft., the longest singlespan being 407 ft. The insulators are 6o,ooo-volt., triple-petticoat, porcelaintype, supplied by R. Thomas & Sons Company, of East Liver-pool, Ohio. The insulators are carried on the cross-arms by. ^ plate 5las3 Qolcs 3 gla! —30 vilriSoJ acwor pipi SECTION THROUGH HIGH-TENSION ROOM AND TRANSFORMER ROOM, SHOWING COURSE OF WIRING SYRACUSE SUB-STATION its supervision. The construction of the sub-station wascommenced Eeb. i, 1906, and it is anticipated current will beturned on about the 15th of the present month. THE TRANSMISSION LINEAs stated, the Syracuse Rapid Transit Company receivesthe current at approximately 55,000 volts from the Niagara,Lockport & Ontario Power Company at the western cityline of the city of Syracuse, and transmits it at this voltagethrough the city of Syracuse for a distance of two miles overits own high-tension line to its new sub-station on the bankof the Erie Canal at Tracy Street. The route of the trans-mission line within the city limits of Syracuse, as will be seenfrom the map on page 75, beginning at the sub-station,crosses the canal and follows the berm side of the canal fora distance of 1500 ft.
