Moran, Jr, J A

This report summarizes the results of an experimental program which developed a needed reliable data base on modern pipe-type cable construction from which designers can knowledgeably consider maximizing cable pulling lengths with resulting cost savings. The program comprised evaluations of available commercial constructions over the range of conductor sizes (both copper and aluminum) and insulation thicknesses in general utilization. The work focussed on determining the cable's performance under the three mechanical stress modes to which the cable is subjected during installation; (a) tension and elongation, (b) torsion and (c) sidewall (bearing) pressure in bends. Additionally, the program included experimentation to determine the effective coefficient of friction of the various combinations of modern skid wire materials and pipe filling oils used as lubricants with the cable in both triangular and cradled configuration. The cables tested were equipped with pulling bolts of various commercial and experimental designs permitting evaluation of their suitability for severe pulls.
