The invention relates to a cable arrangement (CA) where three cables (L1, L2, L3) have at least two cross-bonding locations (SCB) when transmitting power between a first location (A) and a second location (B). At the cross-bonding location (CBL) not only the screens (51L, 52L, 53L; 51R, 52R, 53R) but also the water sensing wires (71L, 72L, 73L; 71R, 72R, 73R) are cross-bonded in cross-bonding devices (WCBD, SCBD). Thus, voltage differences between the water sensing wires and the screens of the respective cables in the three- phase system can be avoided. The invention finds particular application in high power transmission systems using high voltage cables.
L'invention concerne un agencement de câble (CA) dans lequel trois câbles (L1, L2, L3) possèdent au moins deux emplacements de permutation de connexion (SCB) lors de la transmission d'énergie entre un premier (A) et un second (B) emplacement. Au niveau de l'emplacement de permutation de connexion (CBL), non seulement les écrans (5¿1L?, 5¿2L?, 5¿3L?; 5¿1R?, 5¿2R?, 5¿3R?) mais également les fils hydrosensibles (7¿1L?, 7¿2L?, 7¿3L?; 7¿1R?, 7¿2R?, 7¿3R?) sont permutés dans des dispositifs de permutation de connexion (WCBD, SCBD). Ainsi, il est possible d'éviter des différences de tension entre les fils hydrosensibles et les écrans des câbles, des câbles respectifs du système triphasé. L'invention s'applique notamment à des système de transmission de puissance élevée mettant en oeuvre des câbles haute tension.
