How do you convert the alternating current voltage value (AC) of an ÖLFLEX® cable into the corresponding direct current voltage value (DC)?




For virtually all of our ÖLFLEX® cables, the rated voltage is specified in the form of an AC value (Alternating Current). In a DC system (Direct Current), the rated voltage of the system must not be greater than 1.5 times of the rated voltage of the cable.
To calculate the DC value, the relevant AC value is simply multiplied by a factor of 1.5, as in the examples below:


AC Alternating current       Factor      DC Direct current
U0/U 300/500 V                    x 1.5          U0/U 450/750 V
U0/U 450/750 V                    x 1.5          U0/U 675/1125 V
U0/U 600/1000 V                  x 1.5          U0/U 900/1500 V

The electrical voltage is measured in Volt (V).
