Cable Diameter Calculation Formula:
Cable diameter Dcable is equal to the 1.2 times of square root of the total number of conductor N times of the square of the conductor diameter dconductor. Hence cable diameter calculation formula can be written as,
Cable diameter Dcable = 1.2 x √ (N x dconductor2)
For multiple N core,
Cable diameter Dcable = 1.2 x √ ((Ncore1 x dconductor-core12)+ (Ncore2 x dconductor-core22)+…+ (NcoreN x dconductor-coreN2)))
