DIAGRAM AND FRONT ELEVATION OF SUB-STATION SWITCHBOARD are inside next the core, the primaries above and ducts are left between the coils, core, casing and eachother to afford free passage for the blast, which, entering below,may be regulated by a baffle above. The core plates are of the best annealed soft iron, coatedwith a special insulating japan, in two widths, as a first ap-proximation to a circular section. The primary leads pass outat a pair of corrugated porcelain bobbins sealed into the hoodand screw-couple to the leads emerging from the h. t. chamberthrough a tall end gland, ebonite screw sockets encasing thenaked connection. The windings may be readily inspected onunscrewing the sheet-iron sides. The secondary loads passunder the-floor up the slip ring stand. The primaries wereflashed at 15,000 volts to earth and secondaries, the latter at2500 volts to earth. Each transformer weighs approximately5450 lbs.
