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
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 term "pipe bending radius 40D" refers to the minimum radius at which a pipe can be bent, where "D" represents the diameter of the pipe. Therefore, a 40D bend means the bending radius is 40 times the pipe's diameter. For example, if the pipe has a diameter of 2 inches, the minimum bending radius would be 80 inches. This specification helps ensure the integrity and performance of the pipe during bending, preventing kinks or damage.
Radius of curvature divided by tube diameter. To get the radius of curvature, imaging the bend in the tube is a segment of a circle, the radius of curvature is the radius of that circle.
There is no difference. Different suppliers and contractor describe the same situation with 3R or 3D. Here is how to think about it. A piping segment is formed or bent at a radius. The radius is measured at the centerline of the bend. The radius of the bend centerline is 3 times the nominal diameter of the piping segment being bent. 3R means the bend radii is three times the nominal pipe diameter. 3D means three times the nominal pipe diameter is the bend radii of the piping segment. Caution don't begin to convert 3R to 1.5D. Not applicable with this terminology. Standard long ells can be purchased with 3R bends, being 10 inch pipe ells have a bend radii of 30 inches.

The minimum radius of a cable tray bend is governed by several factors, including the type and size of the cables being used, the manufacturer's specifications, and applicable industry standards. A bend that is too tight can damage the cables, leading to performance issues or failure. Typically, it's recommended to maintain a bend radius that is at least 1.5 to 2 times the outer diameter of the largest cable in the tray to ensure safe and effective installation. Additionally, local codes and regulations may also dictate specific requirements for bend radii.

Use the curvature of a tennis ball as a good guide. Try not to bend fiber cables any more than this. The maximum bend (called the maximum bend radius) for any fibre optic cable is determined by the manufacturer, and improvements are being made all of the time. With todays cables, if you bend a fiber optic cable 90 degrees (so it is shaped like the letter L) you will surely damage it. You want to have smooth, gradual curves, and don't go beyond the radius of a tennis ball.
I believe you want to know the MINIMUM bending radius of sheet metal. The maximum bend would be 180 degrees.
The transmission is unreliable after the bend radius is exceeded.

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
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.
