Trusted by global companies for 10 years

A Wide Range of Outstanding Features

All the Installation Methods

Cable current rating calculations in custom arrangements for your site specific conditions.

Complies with Standard IEC Standards 60287 and 60853.

In Air and Groups in Air

Unenclosed - exposed to sun or shaded. Enclosed in ducts. Groups of multi-core or single core cables. Adjust ambient air temperature.

Bonding Arrangements

Considers cable screen/sheath/armour circulating and eddy current losses. Solid, single-point or cross-bonded earthing arrangements.

Direct Buried or In Ducts

Equally or unequally loaded multiple buried circuits in any custom arrangement of any cable type. Soil dry-out around cables.

Buried in Thermal Backfill

Multiple custom cable arrangements buried direct or in ducts in thermal backfill. Soil temperature plots.

Modules in the Full version

Powerful add-on modules which dramatically extend the capability.

Emergency and Cyclic Ratings

Transient rating calculations to Standard IEC 60853 and Neher-McGrath methods.

Short-circuit Ratings

Adiabatic and non-adiabatic short-circuit ratings for metallic components of custom cables.

Magnetic Fields

Magnetic field intensity in micro Tesla at any height above the ground for any arrangement of buried or in air cables.

Cable Crossings

Calculate derating to IEC 60287-3-3 for multiple cable circuits or heat pipes crossing at any angles.

Unfilled Troughs

Derating factors for cables installed in unfilled cable troughs where the trough is buried and covered on all sides up to ground level.

Randomly filled cable trays

Ratings for cables installed in bundles in cable trays with options for fire-rated insulation, cable tray covers, custom diversity and solar radiation.

Graphical Cable Modelling

Very easily build custom cable models based on their construction.

Custom Cables

Using the datasheet or manufacturers catalog easily build cable models for custom rating calculations.

Database of Cables

Includes hundreds of pre-modelled cables from LV to 500 kV (5 kV DC).

Multiple Cable Types

Single core or multi-core, DC, single phase or 3 phases. Copper or aluminium. Screened, sheathed or armoured cables.

Variable Frequency

Use for 50 Hz or 60 Hz systems and high frequency applications such as motor drives.

Advanced Reporting

Beautiful, comprehensive and easy to understand reports.

Detailed PDF Reports

The reports include the input data, detailed results and show compliance.
