Text Appearing Before Image:
minal yard construction is designed to support two trolleys from twocross-suspended wires stretched between light tubular steel supports. Vertical steelsupports are in tripod form, and, where they straddle 6 tracks, a horizontal tie baris placed between the upper ends of the tripods. The uprights are fixed to earthplates imbedded in two feet of concrete, and take up a very small portion of the way,give great stability, are cheap, and do not obstruct the view of signals. Simplon Tunnel construction involves copper plated steel cross wires stretchedbetween gun-metal studs grouted into the face of the tunnel, the cross wires being TRANSMISSION AND CONTACT LINES 451 insulated with common porcelain and drawn tight. The studs are 82 inches apart.The trolley wire is secured by means of ebonite-covered bolts to gun-metal cross bars,the ends of which are screwed into bell-shaped porcelain insulators, a layer of hempand asbestos being interposed between the screws and the porcelain at each end.
Text Appearing After Image:
Fig. 175.—Great Northern Railway. Insulator Support in Concrete Roof of Tunnel, Paral-lel TO the Contract Line. These porcelain insulators are in turn screwed into gun-metal end caps with a layerof rubber, which is imposed to give elasticity to the whole insulator and thus to pre-vent a fracture. The insulators are tested to 40,000 volts, while the maximumworking voltage is 3300.
