Step 3 check calculate voltage drop.
Cable drum size calculation formula.
Now you can take the advantage of this calculator to do this job j you can also check the classical wire cable size calculator in awg calculating wire cable size formula for single phase circuits.
Number of cable per trench is 1 number of run of cable is 1 run.
Below is the formula to calculate the voltage drop of an electrical circuit based on the wire size and load current.
Fill diameter is the flange diameter less 2 which allows for an inch of clearance.
Wire rope estimator tugger wire rope calculator winch cable capacity.
Steel drums can vary in size from 630mm to 10000mm and carry loads of up to 250 tonnes.
This formula is based on the prac tices of wire rope manufacturers and assumes uniform winding of the wire rope.
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.
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.
The appropriate storage of cable drums and the electrical cable it contains will depend on both the type of drum and whether or not the cable itself is designed for indoor or outdoor use.
Length at 100 of perfect wind feet.
Required cable size mm 2 voltage drop volts percentage drop load amps reset.
Choose the cable size whichever is greater in step 1 or step 2.
Full drum capacity is typically calculated using the formula shown below.

Length at 75 of perfect wind feet please verify this guide with actual put ups as variables of tension lay material type etc.
Ingersoll rand has reviewed and used drum storage formulas offered in engineering hand books and those of various wire rope manufacturers.
This formula is based on the practices of wire rope manufacturers and assumes uniform winding of the wire rope.
No guarantee as to the accuracy of these values is given.
How should electrical cable drums be stored.
The full drum capacity is calculated below using the formula below.
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.
And they should be checked with an electrician.
Cable is directed buried in ground in trench at the depth of 1 meter ground temperature is approximate 35 deg.
Length at 90 of perfect wind feet.
An example how to calculate voltage drop and size of electrical cable photo credit.
Check for voltage drop with the cable size chosen.
We do not guarantee it will match other rope or winch manufacturers methods or results.
