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.
4 times 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
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.
To calculate the dimension of a 90-degree bend in a Bar Bending Schedule (BBS), you need to determine the bend radius and the length of the bent bar. The formula typically used is: Length of bend = (π/2) × Bend Radius + Straight Length before and after the bend. Ensure to account for the bar diameter when determining the bend radius, as it affects the overall length. Finally, sum these lengths to get the total dimension for the 90-degree bend.

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

Four times the outer jacket diameter.
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.
The RADIUS of a 5D pipe bend is actually what is 5 times the nominal diameter. So if you had a 10" diameter pipe, the radius of the centerline of the bend would be 50 inches.
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.
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.
A 3D bend is a pipe bend that the bend radius is 3 times the pipe outside diameter.
To calculate the degrees per meter required to bend a 16" pipe to a 10D bend, you would first need to determine the bend radius using the formula: Bend Radius = Pipe Diameter x Bend Factor. For a 10D bend, the bend factor is 10 (D = diameter) so the bend radius would be 16 x 10 = 160 inches. To find the degrees per meter, you would then calculate the angle of the bend (usually 90 degrees for a standard 10D bend) divided by the total length of the bend in meters (which would be the circumference of the bend radius).
