Bending Radius of Cables

The Bending radius of a cable refers to the sharpest possible bend a cable can take.  Cables are flexible conductors and they needed to be bent at numerous places as they carry power.

Cable manufacturers usually specify the minimum possible radius that a bend can take.  This is known as the bending radius.  If the cable is bent at a radius below the minimum specified radius, the cable can get damaged.

 As a rule of thumb, the bending radius is 10 to 15 times the diameter of the cable.  However, the bending radius value provided by the manufacturer should be consulted before laying any cable.
