Electric cable bending testing method for evaluating service life of cable, involves subjecting section of cable to proper torsion or rotation at angle of specific degrees and to rotary to-and-fro movement in horizontal plane

摘要

The method involves choosing a measurement point (14) of an electric cable (13) at which bending resistance of the cable is measured. A section of the cable extending from the measurement point is subjected to a rotary to-and-fro movement in a horizontal plane. The section of the cable is subjected to a proper torsion or rotation at an angle of 90 degrees after the section is subjected to the to-and-fro movement. The section of the cable is subjected to another rotary to-and-fro movement in the plane. An independent claim is also included for an installation for testing bending of an electric cable.
