Miscellaneous technical information
Calculation of the Minimum Radius of Curvature.
To obtain the minimum bending radius without damaging the cable, the Diameter (D) of the cable must be multiplied by the value indicated in the catalog in order to obtain the possible Radius (r)
Description found in catalogs (Example): Min radius. of curvature: 10 x d.
Calculation of voltage drop.
1-) Single-phase system
The percentage voltage drop will be given by:
2-) Three-phase system
The percentage voltage drop will be given by:
Where:
V = voltage between phases (V)
L = cable length (km)
R = alternating current resistance of the cable ( W /km)
X = inductive reactance of the cable ( W /km)
cos j = power factor of the load
Average consumption of household appliances
