[0029] Furthermore, in this embodiment, the first connecting member 3 may be a bolt, so that the clamping force of the armored steel wire 100 can be adjusted by adjusting the tightening degree of the bolt to ensure that the tensile strength of the armored steel wire 100 is not affected.

[0030] It should be noted that the fixing fixture provided in the embodiment of the utility model is used to fix most of the armored steel wires in the armor layer of the submarine cable.

[0031] The fixing clamp for the armored steel wire of the submarine cable provided in the embodiment of the utility model can clamp the armored steel wire between the first fixing piece and the second fixing piece by arranging a first fixing piece, a second fixing piece and a first connecting piece, thereby ensuring that the tensile strength of the armored steel wire is not affected, thereby meeting the use requirements of the armored steel wire in an underwater working environment.
