Tech/Engineering - Energy / Power Generation / Guidelines for the selection of electrical conductors for mining industry solutions/conductor cables for mines
Spanish term or phrase: conducción de corriente instalados al aire
Calibre mínimo por capacidad de conducción de corriente

A continuación se presentan unas tablas para la determinación del calibre mínimo de los conductores de los cables de minas, en las que se indica la capacidad de conducción de corriente (que es la máxima corriente que pueden transmitir los cables sin sobrepasar la máxima temperatura permisible en el conductor, la cual está determinada por las características del aislamiento) en función del calibre del conductor, para los diferentes tipos de cables. En estas tablas se considera lo siguiente:

-Capacidades de **conducción de corriente al aire** de cables para minas de tres conductores tipo MP-GC de 2,001 a 15,000 V

Nota A: Capacidad de **conducción de corriente instalados al aire**, con temperatura en el conductor de 90 y temperatura ambiente de 40° C.

Many thanks for your help!!!

neutral  Fiona Kirton: These are cables to be used in a mine, so they're unlikely to be overhead lines.
