Recommended Cleat Spacings

150The following illustration shows the tensile strength required by each cable cleat depending upon fixing centres/intervals.

 = 0.17  / S
 = maximum force on the cable conductor (N/m)

0.17 (190 x 190) / (36 / 1000) = 170,477.22 N/m
Cable Ø = 36mm  = 190kA
mounting intervals: 300mm (x 0.3) = 51,141.67N per cable cleat

0.17 (190 x 190) / (36 / 1000) = 170,477.22 N/m
Cable Ø = 36mm  = 190kA
mounting intervals: 600mm (x 0.6) = 102,283.33N per cable cleat.
Each cable cleat in this configuration must restrain two times the force
of those in the above configuration (300mm).

0.17 (190 x 190) / (36 / 1000) = 170,477.22 N/m
Cable Ø = 36mm  = 190kA
mounting intervals: 900mm (x 0.9) = 153,424.00N per cable cleat.
Each cable cleat in this configuration must restrain one-and-a-half times the force of those in the above
configuration (600mm), or three times the force of those in the first configuration (300mm).
