Concept cables limited is an independent insulated wire and cable manufacturer providing cabling solutions for a whole spectrum of industries across the uk europe and worldwide.
Fill diameter is the flange diameter less 2 which allows for an inch of clearance between flange edge and wire.
For more information about the size and dimensions of the drums we have a drum guide chart that you can find here below.
The reactance for single core cables is selected from the flat touching column in from table 30 in as nzs 3008.
In actual practice drum capacities may be 25 30 less than the values given by this formula due to uneven spacing loose winding and overlapping.
We do not guarantee it will match other rope or winch manufacturers methods or results.
This is the worse case scenario.

Please verify this guide with actual put ups as variables of tension lay material type etc.
This formula is based on the practices of wire rope manufacturers and assumes uniform winding of the wire rope.
Ingersoll rand has reviewed and used drum storage formulas offered in engineering hand books and those of various wire rope manufacturers.
It is recommended that an allowance of up to 30 be made to accommodate loose winding.
We have gleaned the best of these methods and offer this electronic calculator for our customer s convenience.
