Prestressed concrete conductor masts in South Africa
Total lengths of masts for supporting overhead conductors in connection with railway electrification, are from 33 ft 9 in. to 37 ft 3 in.; at level of top of foundation mast is U-shaped; near the top, cross section is similar to that of rail; description of vibro-pressure casting; data on reinforcement; method of testing shown diagrammatically.
