L'invention améliore la résistance aux interférences et la sécurité de fonctionnement d'un câble électrique au moyen d'une conception structurale et d'une sélection de matériau raisonnables. Le câble électrique comprend deux fils de puissance principaux (1) disposés en parallèle en une seule rangée. Un espace formé par les deux fils de puissance principaux (1) disposés en parallèle en une seule rangée l'un par rapport à l'autre est enveloppé de manière séquentielle par une couche de blindage (2), une couche de séparation (3), et une couche de protection (4) qui ont une forme ovale ou une forme de type ovale. Spécifiquement, la couche de blindage est une couche de blindage tissée, et la couche de séparation est une couche de séparation et de blindage métallique. Un grand axe de la forme ovale ou de la forme de type ovale est parallèle à une ligne reliant les centres des deux fils de puissance principaux. Un espace entre les fils de puissance principaux dans la couche de blindage ne contient pas d'élément de remplissage.
