Why is there a minimum allowable bending radius specified for cables?
The minimum allowable bending radius for cables is specified to ensure that the cables operate without damage or significant reduction in lifespan, and is not explicitly defined. The smaller the minimum bending radius, the better the bending performance.
The minimum bending radius refers to the smallest turning radius at which a material can operate without sustaining damage or experiencing a significant reduction in its lifespan. It represents the minimum value of the bending radius that can be achieved without causing any damage to the material.
For instance, the long-term allowable operating temperature of a flame-retardant rubber-sheathed cable core is 65°C, and the minimum bending radius of the wire is 6 times the diameter of the cable.
