| Protection des lignes de télécommunication à conducteurs métalliques contre les décharges directes de foudre |
 |
La présente Recommandation décrit une procédure visant à protéger les lignes de télécommunication, à conducteurs métalliques, contre la foudre, qu'il s'agisse de la ligne elle-même ou des structures par lesquelles la ligne pénètre. Cette procédure doit permettre de protéger les lignes contre les effets directs de la foudre. Elle porte sur le choix des caractéristiques du câble et son installation, la mise à l'équipotentiel/à la terre du blindage du câble, l'utilisation de fils de blindage, l'installation de parafoudres (SPD, surge protective device) et la redondance de cheminement. |
