FO 00.02-1 Cable properties

Created by M. Wolf |

Case 1:
A comparison between information according to the manufacturer’s data sheet and the test results of “Tensile performance and cable bending under tension” (operational and installation conditions, under tension, with fixed S-shaped deflecting bends.
