Cableizer does currently support AC voltage levels from medium voltages of 1 kV up to extra-high voltages of 500 kV. DC voltage levels are currently limited to below 5 kV. For low-voltage cable sizing, alternatives to Cableizer are readily available.

For a comprehensive overview of supported rated cable voltages in Cableizer, including their corresponding highest equipment voltages, test voltages, and IEC standards coverage, refer to the documentation about the rated cable voltage.
In Cableizer, voltage levels are categorized according to the following table:
| Low voltages | LV | $U_m$ <= 1 kV |
| Medium voltages | MV | 1 kV < $U_m$ <= 52 kV |
| High voltages | HV | 52 kV < $U_m$ <= 245 kV |
| Extra-high voltages | EHV | 245 kV < $U_m$ <= 800 kV |
| Ultra-high voltages | UHV | $U_m$ > 800 kV |
Cableizer support following voltage levels
| Rated phase-to-phase voltage $U_n$ | Highest voltage for equipment $U_m$ | Operating voltage $U_0$ | Relevant standard |
