I would call it wire rope, or a support line. If I worked with it often enough, I'd probably refer to it by size or construction (EHS, 7x7, etc) I'd argue that a Bowden cable (eg a clutch cable) is primarily carrying a signal... really though, just thinking through what defines a cable. By contrast, rope and line are terms with fairly specific meanings.
