What is the meaing of Cable Training (Offset bending) ?

Cable Training (Offset bending)

You may use the following formula to determine the minimum distance necessary for permanent cable training (offset bending) in a manhole:
         ____________
L = √ S (4 R – S)

Where:

L = Minimum distance required (in)
S = Offset (in)
R = Bending radius to cable centerline (in)
