Results are reported of fatigue and wear tests conducted on samples of wire sheathed Paulsen-Webber, design number 1, special purpose tow cable. The results of the tests indicate that the initial break in the outer wire covering of the cable occurs between 13,000 and 22,000 cycles of operation in the wire rope fatigue machine and a significant number of breaks occur after 28,000 to 36,000 cycles of operation. Inner wire failures were also observed in one sample operated for 36,000 cycles and in two samples operated for 70,000 cycles. The electrical components of the sample cables did not appear to be damaged as a result of the fatigue and wear tests. Author
