How to find the min and max bending radius of a cable.

...the future was a moment ago, and life is still just a scheme away....;)

Substituting the OD of the cable into the second equation:

5 x 10.2/3 x 10.2 = 173mm minimum bend radius.

Am I missing what you’re asking?

Silly answer:  Install all your components in orientations that allow cabling to run in straight lines.  Then there is no danger of damaging or degrading them.


Sensible answer:  Cables come coiled in a box by the manufacturer.
One presumes he does not bend them enough to damage or degrade them.
Most are coiled more tightly than is required in most installations.  Therefore don't bend them more than they are bent on delivery.

The cable manufacturer should be able to answer what is the minimum bend radius. This is a very typical specification for industrial cables, especially those marketed/intended for continuously moving/bending applications. For home audio purposes, this doesn't seem relevant.

Bending limits are determined by a combination of the thickness and hardness properties of the insulation/jacketing, and conductor diameter, construction (stranded/solid), and material (copper/aluminum/silver).

I recommend avoiding situations where tight bends are necessary. If tight bends are necessary, Morrow Audio (and similar non-braded individually-insulated multi-strand designs) will perform well - because the strands are not bound together, and free to move inside the bundle without strain or binding.

@edomks You've asked the question, and so, why does this question pertain to you currently?
