Number of cable per trench is 1 number of run of cable is 1 run.
Cable drum size calculation formula.
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.
Length at 90 of perfect wind feet.
Fill diameter is the flange diameter less 2 which allows for an inch of clearance.
Choose the cable size whichever is greater in step 1 or step 2.
How should electrical cable drums be stored.
Required cable size mm 2 voltage drop volts percentage drop load amps reset.
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.
To calculate these fields.
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 wind ing and overlapping.
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.
Full drum capacity is typically calculated using the formula shown below.
Length at 100 of perfect wind feet.
Step 3 check calculate voltage drop.
Length at 75 of perfect wind feet please verify this guide with actual put ups as variables of tension lay material type etc.
The full drum capacity is calculated below using the formula below.
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 prac tices of wire rope manufacturers and assumes uniform winding of the wire rope.

An example how to calculate voltage drop and size of electrical cable photo credit.
This formula is based on the practices of wire rope manufacturers and assumes uniform winding of the wire rope.
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.
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.
