Today we are here with another comprehensive copper and aluminum wire size calculator as we have discussed in detail the topic of how to calculate the proper wire size for electrical wiring.
Cable drum size calculation formula.
The full drum capacity is calculated below using the formula below.
Number of cable per trench is 1 number of run of cable is 1 run.
This formula is based on the practices of wire rope manufacturers and assumes uniform winding of the wire rope.
Choose the cable size whichever is greater in step 1 or step 2.
Fill diameter is the flange diameter less 2 which allows for an inch of clearance.

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.
Cable is directed buried in ground in trench at the depth of 1 meter ground temperature is approximate 35 deg.
Check for voltage drop with the cable size chosen.
Below is the formula to calculate the voltage drop of an electrical circuit based on the wire size and load current.
Step 3 check calculate voltage drop.
Caution for guidance only.
And they should be checked with an electrician.

Steel drums can vary in size from 630mm to 10000mm and carry loads of up to 250 tonnes.
No guarantee as to the accuracy of these values is given.

Ingersoll rand has reviewed and used drum storage formulas offered in engineering hand books and those of various wire rope manufacturers.
In actual practice drum capacities may be 25 30 less than the values given by this formula due to uneven spacing loose wind ing and overlapping.
This formula is based on the prac tices of wire rope manufacturers and assumes uniform winding of the wire rope.
Full drum capacity is typically calculated using the formula shown below.
