Figure. 5.4.12 - 123. Example of a high-voltage cable datasheet.
The datasheet shows the currents which in a combination with a specific installation and a specific
construction method achieve a specific conductor temperature in give standard conditions (e.g. a
copper conductor reaches a temperature of 90 °C when, for example, it has a continuous current-
carrying capacity of 815 A, an open screen circuit, and is laid in a trefoil formation in soil whose
temperature is 15 °C).
The most important parameters for setting a working thermal image are the cable's current and the
installation place. In addition to the above-mentioned current-carrying capacity table, the manufacturer
should also provide data to allow for fine-tuning the thermal image. Equally important to the
ampere–temperature values are the presumptive conditions under which the given continuous current-
carrying capacity values can be expected to apply. The following figure is an example of these general
presumption as presented in a Prysmian Group cable datasheet.
