Cable High Voltage
Standard IEC 60287 and Neher-McGrath methods
Accurate cable rating calculations of custom cables from LV up to 500 kV.
Wide range of installation conditions: In Air, In Groups, Direct Buried or in Ducts, Buried in Backfill, Multiple Buried Circuits, Unfilled Troughs, Filled Cable Trays.
Wide range of installation methods can be analysed:
- Unenclosed in air – exposed to sun or shaded.
- Enclosed in ducts/conduits.
- Groups of cables.
- Direct buried – optionally consider dry-out of soil.
- Backfilled trenches (areas with different soil thermal resistivity).
- Buried in ducts/conduits.
- Unfilled troughs.
- Filled cable trays.
Features and Benefits:
- Complies with:
- IEC 60287 – Calculation of current ratings

- Suitable for low voltage up to high voltage cables (500 kV AC or 5 kV DC).
- Database of LV, MV and HV modern extruded power cables from various manufacturers incorporated with software.
- Enter custom cables from manufacturer datasheets.
- AC or DC cables.
- Single phase or three phase extruded cables.
- Multi-core or single core cables.
- Solid, single-point or cross-bonded sheathed and armoured cables.
- Short-circuit module for rating of power cables for short-circuit currents.
- Based on IEC 949 – Calculation of thermally permissible short circuit currents, taking into account non-adiabatic heating affects.
Solar Radiation Intensity:
- Calculate maximum expected solar radiation intensity (W/m2) based on location.
Soil Temperature Variation with Time and Depth:
- Calculate expected soil ambient temperature for time of year and depth of burial.
- Duct and conduit selection based on dimensions from Standards.
1. Is the software suitable for Low Voltage and High Voltage cables?
