Bending radius of MV-105 wire - 300.34?

[Twophase]

Running some MV-105 wire for a 4160V system. Four wires (3/C+GND), all #2 AWG. Per 300.34 (2017), the I understand the bending radius to be 12x the diameter of the wire (including insulation). Looking at the wire I plan to use (#2 AWG, 0.76" diameter), I get a radius of 9.12". I plan to run this through a 90 deg elbow (which has R=10"), down some straight conduit, then through an elbow again, straight for 2 feet, and then a final elbow. One of my colleagues mentioned that there may be a limitation on the number of subsequent bends when using MV wire, but couldn't quote where in the code this is from (if it even is from the code). Any issue with what I have described, provided that the elbow R>wire bending R?

Thanks!

There’s a 360 degree limitation
Look at NEC 358.26.

Thanks. I am aware of that requirement. I was wondering if there were any additional requirements for MV wire bends.

There are no additional requirements.
