We have benchmarked our Cable HV Software current rating results for 110 kV cables against the well-known software CYMCAP. We have shown the results are virtually identical (under 1.5 % difference).

The current rating of bare conductors is affected by the conductor temperature, weather parameters, heat losses due to convection and radiation, the solar heat gain and conductor resistance, the calculation of which is governed by a steady-state and a non-steady-state heat balance equation.
