Armouring joint, an armoured cable joint and a method for jointing armouring of two armoured cables

摘要

The invention concerns an armouring joint (10) between a first armoured cable comprising N first armouring stranded wires (1A to 8B) and a second armoured cable comprising N second armouring stranded wires (1′A to 10′B), characterized in that a number K lower than N of first armouring wires (1′B to 8B), called shorter first wires, are shorter than N-K first armouring wires (1A to 10A), called longer first wires, a number N-K of second armouring wires (3′B to 10′B), called shorter second wires, are shorter than K second armouring wires (1′A to 10′A), called longer second wires, and in that K shorter first wires (1B to 8B) and N-K shorter second wires (3′B to 10′B) are respectively abutting or nearly abutting with K longer second wires (1′A to 10′A) and N-K longer first wires (1A to 10A), thereby forming an armouring common zone (11) comprising first and second armouring wires (1A to 10A, 1′A to 10′A). The invention also concerns an armoured cable joint and a method for making or repairing an armouring joint.
