In the substation in Butte 2640 k. w. capacity instep-down transformers will be installed of the same de-sign as those in the main station, but of various sizedunits best adapted to the several uses for which they areto be employed. The high tension side of these trans-formers are wound for 13,250 volts and the low tensionside for 2200. Both the main and substation will be provided with. FIG. 10.—POLE OF TRANSMISSION LINE two electric blower sets for circulating the air through thetransformers. The switchboard will be made of blue Vermontmarble and consist of 15 panels, divided as follows: 4 generator panels, 1 main station panel, 1 parallel-ing panel, 4 high tension transformer panels, 1 exciterpanel, 2 line panels, 2 low tension transformer panels. The high tension portion of the main station switch-board will be located in the transformer building in a posi-tion where the attendant at the main switchboard can seeit at all times. The panels will be equipped with all of the latest im-proved instruments, and the station protected with Gen-eral Electric lightning arresters. All generator and lowtension transformer leads will be carried under the floorbetween the generator foundations, and will be accessibleat all times for inspection, as there is ample room for aman to walk through the entire length.
