The generator voltage is 4400 at 00 cycles, 3-phase, andis stepped up through two banks of single phase 3,000 to 60,000 volts for transmission purposes. Themain transmission line, which is 32 miles in length, ter-minates at Ardley, a point on the Great Northern Railway,almost equidistant from Vancouver and New Westminster. The standard transmission towers carry two three-phasecircuits of No. O hard drawn stranded copper cable withhemp centre, and one 3/8 galvanized steel ground wire theover all height being 59 ft. and the point of support of the. W. G. 1. Receiving Station ut Ai-dley, B. C. lowest wire being 11 ft. above the ground. The standardspan is 660 feet, but is was necessary to vary this consider-ably at times, owing to inequalities in levels of standard towers are built and were satisfactorilytested to withstand strains of 2,000 lbs. in any horizontaldirection at any point of support for the lines, or H,000 Ib-^. • Electrical Engineer, WoBtern CnnmlfV Power Co. in any horizontal direction on the tower as a whole at thecentre of gravity of the points of support. The verticalloading is 1,500 lbs. on each point of support or 9,000 the tower as a whole. For dead ends or sharp angles,anchor towers are used capable of withstanding twice thestrains of the standards. The standard tower has angle iron posts set 6 ft. 6 the ground, bolted at the bottom to a cross of angle
