We performed ampacity calculations for hundreds of industrial and utility power cables from Southwire. The assumptions used for modelling in the software are explained. The calculated ampacities were all within 3 % of the values given in ICEA and NEC standards.

This article analyses the magnetic fields produced by electrical power cables installed in various configurations under varying conditions in the context of a health and safety-related issue. A software program has been used for calculating the results based on the Biot-Savart law. Techniques for the mitigation of magnetic fields are also presented.

The calculation of submarine cable current ratings is different from land cables due to their complex construction and installation conditions.

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.

This article provides a timeline of the key milestones from early 19th century insulated wires through to modern innovations in high-voltage cables.

Soil temperature affects high voltage cable and earthing systems. Equations for soil temperature calculations based on air temperature are provided.
