This formula is based on the practices of wire rope manufacturers and assumes uniform winding of the wire rope.
Cable drum size calculation formula.
Full drum capacity is typically calculated using the formula shown below.
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.
Required cable size mm 2 voltage drop volts percentage drop load amps reset.
This formula is based on the prac tices of wire rope manufacturers and assumes uniform winding of the wire rope.
Length at 90 of perfect wind feet.
Check for voltage drop with the cable size chosen.
To calculate these fields.
Ingersoll rand has reviewed and used drum storage formulas offered in engineering hand books and those of various wire rope manufacturers.
We have gleaned the best of these methods and offer this electronic calculator for our customer s convenience.
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.
Choose the cable size whichever is greater in step 1 or step 2.
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.
Length at 75 of perfect wind feet please verify this guide with actual put ups as variables of tension lay material type etc.
Length at 100 of perfect wind feet.
An example how to calculate voltage drop and size of electrical cable photo credit.
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.
We do not guarantee it will match other rope or winch manufacturers methods or results.
Caution for guidance only.
Fill diameter is the flange diameter less 2 which allows for an inch of clearance.
Step 3 check calculate voltage drop.
The full drum capacity is calculated below using the formula below.
How should electrical cable drums be stored.
Cable is directed buried in ground in trench at the depth of 1 meter ground temperature is approximate 35 deg.
Steel drums can vary in size from 630mm to 10000mm and carry loads of up to 250 tonnes.
