Germany's centrifugal concrete poles
Hollow round transmission line poles are of centrifugally cast concrete, reinforced with steel rods and spirals; result is claimed to be non-porous, homogeneous high elastic concrete of marble density; surface develops completely water repellent cement rich coating; 90 ft lengths are used for power lines, 4-piece poles for high voltage lines; load capacity varies from 220 to 1200 lb; poles are suitable for transformer lines of up to 250 kva capacity.
