Embodiment Construction

[0022] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0023] Such as figure 1 As shown, a method for flexible connection of two cable armor layers, including two first cables 1 and second cables 2 with armor layers, the metal wires in the two cable armor layers pass through the flexible The common area 3 of the joint is connected continuously, and the length of the common area 3 of the flexible joint is at least 1 times the pitch of the armor of the cable body. The number of metal wires in the armor layers of the two cables can be the same or different. The flexible joint public area 3 includes five wire connection interfaces: the first wire connection interface 31, the second wire connection interface 32, the third wire connection interface 33, the fourth wire connection interface 34, the fifth The metal wire connection interfaces 35 are arranged in a staggered interval between each metal...

Abstract

The invention discloses a method for flexible connection of the armored layers of two cables, and the method employs two cables with the armored layers. The method comprises the steps: enabling metalwires in the armored layers of the two cables to be connected through a flexible connector common region, wherein the flexible connector common region comprises a number of metal wire connection interfaces and the number is a positive integer; enabling all metal wire connection interfaces to be arranged to be staggered at intervals in the length direction and/or radial direction, wherein each metal wire connection interface consists of at least one metal wire connection point, and the metal wire connection points are the joint points of the metal wires of the two cables. According to the invention, a restored diameter is equal to or greater than the diameter of a cable body by several millimeters, and the manufacturing is simple and quick. The armored layer has the same mechanical performances as the cable body, and can be widely used in the field of cable joints with metal wire armed structures: power cables, marine cables, photoelectric composite cables, optical cables and umbilicalcables. The method is widely in application range, and has a certain social significance.

Description

technical field [0001] The invention belongs to the technical field of cable connection, and in particular relates to a method for flexible connection of armored layers of two cables, which can be applied to power cables, submarine cables, photoelectric composite cables, optical cables, umbilical cables and other metal wire armored structures The field of cable joints. Background technique [0002] As an important means of contemporary international communication, submarine optical cable undertakes 90% of international communication services and is the main carrier for the rapid development of the global information and communication industry. The special environment of the submarine puts forward very high requirements for the submarine optical cable system. The construction period of the submarine optical cable is long, the investment is huge, and it involves many links such as development, production, construction and maintenance. Each link requires special technology and...
