Embodiment

[0037] Such as figure 1 and figure 2 A submarine cable is shown, which includes:

[0038] The outer sheath 1 and the inner core tube 2, the cross section of the outer sheath 1 is oval, the cross section of the inner core tube 2 is a rounded rectangle, the outer sheath 1 tightly covers the outside of the inner core tube 2, and when the inner core tube When 2 is a rectangle with rounded corners, the long axis of the ellipse of the outer sheath 1 is parallel to the long side of the rectangle with rounded corners. This embodiment takes a square with rounded corners as an example;

[0039] The inner core tube 2 is composed of an inner sheath 201, an I-shaped frame 202 and a plurality of core wires 203. The core wire 203 is formed by tightly wrapping a plurality of non-woven fabric wrapping tapes 2032 outside the transmission line 2031. The transmission line 2031 is an optical fiber or Conductive wire, which plays the role of transmitting optical signal or electric power, is the ...

Abstract

The invention belongs to the field of cables, and particularly relates to a submarine cable. The cable comprises an inner core tube and an outer sheath tightly wrapping the inner core tube, wherein the cross section of the outer sheath is elliptical, and the cross section of the inner core tube is rectangular; the inner core tube is composed of an inner sheath, an I-shaped framework and a plurality of core wires; and the upper end face and the lower end face of the I-shaped framework are parallel to the long axis of the elliptical outer sheath, and the upper end face and the lower end face ofthe I-shaped framework abut against the side wall of the inner sheath. The submarine cable provided by the invention has good pressure resistance, can reduce compression deformation generated under ahuge water pressure condition, realizes a good protection effect on an internal transmission line, has certain bending resistance, and improves the protection effect on an optical fiber or a conductive wire.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a submarine cable. Background technique [0002] A submarine cable is a cable wrapped with insulating material and laid on the seabed for telecommunication transmission. In 1850, the world's first submarine cable was laid between Calais (France) and Dover (UK), and China's first submarine cable was completed in 1888. [0003] With the development of the times, the demand for submarine cables has gradually changed. The current submarine cables are not only satisfied with the transmission of electric power, but some of them also need to realize the function of transmitting optical signals, that is, derivatives such as submarine optical cables and submarine optical cables are produced, collectively referred to as It is a submarine cable, referred to as a submarine cable for short. [0004] To meet the needs of submarine optical signal transmission, since optical fibers are more fragile than ...
