Experimental Studies of Fatigue Failures of Down Lead Cables.

Abstract

Eight hard drawn copper cables were tested to failure under static lateral axial load and either dynamic lateral load or torsional couple. Due to the large number of test parameters involved and the limited number of specimens tested, firm conclusions cannot be drawn about the fatigue life of copper cables under dynamic lateral or torsional loading combined with axial tension. With axial and lateral load, fatigue failure occurred at 4,000 cycles; with axial and torsional load failure occurred at about 10,000 cycles. (Author)
