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


Hello 

I need to find the minimum off bending radius of the three products the outer diameter is 10.20 mm

There are a lot of factors that determine this other than outside diameter. Contact the vendors. 
I use pre bent cable.

Kniffle offers them in 1degree increments. Memorial Day special on cryo'ed models. Vaccination proof discounts also!
To find the max bending radius measure the length. Since the max radius is a straight line this works every time. 

To find the minimum bending radius grasp the left end in the left hand, right end in the right hand, then bring the two hands together. Again that is left in left, right in right. Beginners screw this one up all the time.
Only the manufacturer can tell you this because the wire assembly is most likely proprietary. 
I never though about it.. I been in some tight spots too..

If it fits it works.. If it don't it won't.. Kind of the rule of thumb for me.

Strange question really.. Lots of luck anyways.

First. Buy two identical cables.
Second: Bend one of the cables until it stops working.
Third: Install the second cable, but don't bend it as much as the one you destroyed.
Warning: This method works, but it is not very good for your bank account.
Many Belden tech specs give the minimum bend radius,
Find a similar cable and check.

When we installed studios RoT was min ≈10x diameter
Um....I’m going to take a wild leap, and assume min/max r. on a given cable dia. is in regard to its’ physical construction and the characteristics of that.....🤔

Otherwise, I’m going to have to market my Particle Accelerator Sleeves for cables of all types ’n stripes.....

NanoNahNuKableKozies.....What you’ve been missing, and didn’t know it....;

Line starts.......Here.
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?
I found the max bending radius of my AQ King Cobras when one of the channels shorted out.
@fbgbill - maybe so I can look at your System page, and compliment you on your cool looking McIntosh stereo? Also ask about that black and white photo on the right, is that in Arizona?

Seriously, thanks for sharing your system, I always appreciate people sharing. Butcher block rack suits it very well, good job mate.
It depends on what the cable is made of. 
The arc the wire or cable naturally want to form. Here is my way of determining.

Take arms length of cable and bring them together into one hand.  Hold it above your head.  That arc it makes on the bottom is where it wants to be.  Or,
Wind coil it up in your hand.  Place it on the floor.  If it uncoils itself, it's to small or tight.

Of course I could force them into smaller radii. Which it will form to. But not be happy. And I want my big dollar cables to be happy.

My 12 foot MIT waterhose biwire is about 16 inches across.  My "came with" interconnects are about 3 inches.
