Electric conductors are elements that transport electric power, and are made of materials that offer little resistance to the flow of current.
The materials used in electrical installations are copper and aluminum due to their high conductivity and relatively low cost. The study of ampacity in cables is the calculation of the temperature elevation of the conductors in a system of cables at steady state.
The conducting capacity of current in energy cables is 608553-1 problem of heat transference.

Losses are energy that turn into heat in the cable, which it is necessary to quantify 608531 order to define the quantity that dissipates into the environment, through thermal resistances. Ampacity studies simulate the behavior of heat in the cables.
These studies permit one to calculate the rise in temperature and current rating for the cable installation. Three current rating studies exist: Cyclic rating factor 68053-1 cables up to and including.
