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.
Cable drum size calculation formula.
We do not guarantee it will match other rope or winch manufacturers methods or results.
To calculate these fields.
Check for voltage drop with the cable size chosen.
This formula is based on the prac tices of wire rope manufacturers and assumes uniform winding of the wire rope.
Required cable size mm 2 voltage drop volts percentage drop load amps reset.

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.
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.
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.
No guarantee as to the accuracy of these values is given.
This formula is based on the practices of wire rope manufacturers and assumes uniform winding of the wire rope.
Below is the formula to calculate the voltage drop of an electrical circuit based on the wire size and load current.
And they should be checked with an electrician.
We have gleaned the best of these methods and offer this electronic calculator for our customer s convenience.
Number of cable per trench is 1 number of run of cable is 1 run.
Full drum capacity is typically calculated using the formula shown below.
Length at 90 of perfect wind feet.
Cable is directed buried in ground in trench at the depth of 1 meter ground temperature is approximate 35 deg.
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.
Choose the cable size whichever is greater in step 1 or step 2.
The full drum capacity is calculated below using the formula below.
Fill diameter is the flange diameter less 2 which allows for an inch of clearance.
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.
