Want this question answered?
The radius of the curve of the inner edge of the bends shall be at least 6 times the external diameter for armoured cable.

I believe you want to know the MINIMUM bending radius of sheet metal. The maximum bend would be 180 degrees.
It depends on the cable. 0 to 5000 volts the minimum bending radius is 6 x diameter of the cable. Above 5000 volts the minimum bending radius is 8 x the diameter of the cable.
For Unshielded cables, it will 8 multiplies cable diameter and for shielded cables, it is 12 multiplies the cable diameter. However, the smaller the bend radius, the greater is the material flexibility.RegardsKelechi
Typically, wires have a bend radius of 10 times the diameter of the wire. Measuring the inside. This is basically to prevent injury or changes in impedance at the bend. Also note that the tighter the bend can damage the insulation in coaxial or triaxial cables and cause lower dielectric strength between layers. Best to install cables where ripples don't form on the surface and moderate force is recommended. MIL-W-5088 has more information.
Every bending mechanism gets governed by the simple bending equation M/I=F/y=E/R
4 times the diameter of the cable
What area was covered by the eye of Katrina.
In my experiences with armored cables such as MC,HCFC the bending radius of the conductor inside is much smaller than the radius you could bend the armored casing. in other words the clad casing is going to break Which could potentially damage the conductors inside and should not be used. As always electrical wiring is not a hobby and should be left to licensed electricians who follow NEC codes and local codes
You are really looking for minumum bend radius. Here are a few links: http://www.engineersedge.com/sheet_metal.htm http://www.thefabricator.com/Bending/Bending_Article.cfm?ID=52
" All bends are elbows but all elbows are not bends." Infact, the pipe is bent to form an elbow. Elbows are pre-fabricated and are firm in design. There are issues with bends since the tickness at the bend radius reduces as we bend the pipe. Sharp bends are normally called Elbows. Bends typically have a minimum bending radius of 1.5 times pipe radius (R). If this bending radius is less than 1.5R, it is called Elbow. Reference to any international / industry standard need to be traced. 1.5, 3 & 4.5 R are the most common bending radii in industry.
