Current Rating of Cables in Multiple Backfills Using the Finite Element Method

A new calculation method based on FEM and IEC 60287 for current rating of HV cables in soils with multiple different thermal resistivities is explained with an example calculation. Modelling the different soil thermal resistivity zones (multiple backfills) is important for obtaining accurate cable current ratings.

Waveform Cables Current Ratings

Waveform cables are commonly used in the UK for low-voltage power networks. The term waveform refers to the way the neutral/earth wires are laid around the cores/bedding. Using this configuration enables the neutral/earth wires to be opened so a connection can be made to the conductors anywhere along its length.
