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
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
Circumference = 2 * Pi * radius Radius = 23 / (2 * Pi) Radius = 3.66 inches
The filet is part of the radius, therefore making the term filet radius. A filet radius measures an inside corner. A corner radius measures an outside corner.
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.
The bending radius of a cable refers to the minimum radius that a cable can be bent without damaging its internal components. It is typically specified by the cable manufacturer and is important to follow to prevent signal loss or breakage of the cable.
I believe you want to know the MINIMUM bending radius of sheet metal. The maximum bend would be 180 degrees.

The formula to calculate the minimum bending radius for steel is: Minimum Bending Radius = (T * Width) / (2 * K), where T is the thickness of the steel, Width is the overall width of the bend, and K is a factor based on the steel's tensile strength and type of steel.
cable radius
The radius of the curve of the inner edge of the bends shall be at least 6 times the external diameter for armoured cable.
Every bending mechanism gets governed by the simple bending equation M/I=F/y=E/R
Sharp bending, cable pinch, spyware, worm virus, sending or receiving of large email, streaming.
The amount of length lost when bending metal depends on factors like the material's thickness, bend radius, and the bending method used. Typically, you can expect to lose around 1-2 times the material thickness during the bending process.
In a HT cable there are 2 layers of semiconductor one on the conductor and second on the XLPE insulation. As we know semiconductor behaves as conductor when temperature rises. So when the HT cable is on load its conductor temperature rises due to this the semicon layer which is on conductor behaves like conductor and as a result overall cross section area is increased. now the second semicon layer which is over XLPE on temp rise behaves as conductor and used for dessipating heat out of conductor as the cable heat due to load.
Frist putt of the main incomer HT side then Rack out the breaker and put the LOTO after that Discharge the cable Both side (HT/LT).
