Problems solved by technology

Even with aluminum alloy wire braided armor, its density is 2.7cm 3 The aluminum alloy has a low melting point and poor corrosion resistance. If this material is used for braided armor, once the cable is penetrated by a shell during a war, the high temperature at the moment of explosion will melt the aluminum alloy braided armor layer. thereby destroying the cable

Embodiment Construction

[0027] In order to make the technical means and creative features realized by the present invention easy to understand, the present invention will be further elaborated below.

[0028] Such as figure 1 As shown, an ultra-light halogen-free low-smoke flame-retardant ship cable includes a conductor 1, an insulating layer 2, a filling layer 3, a wrapping layer 4, a braided armor layer 5 and a sheath layer 6, and the insulating layer 2 Extruded on the conductor 1 to form a wire core, several wire cores are twisted with each other to form a cable core, the wrapping layer 4 is set on the cable core, and a braided armor layer is braided on the outer surface of the wrapping layer 4 5. The sheath layer 6 is set on the braided armor layer 5;

[0029] The conductor 1 adopts tinned oxygen-free copper type 2 stranded flexible conductor. On the premise of ensuring the standard resistance, the diameter of the single wire is reduced to reduce the weight of the cable conductor. During the bo...

Abstract

The invention relates to an ultra-light halogen-free low-smoke flame-retardation ship cable, and the cable comprises conductors, insulating layers, a filling layer, a wrapping layer, a woven armored layer, and a sheath layer. The insulating layers wrap the conductors to form wire cores. A plurality of wire cores are twisted together to form a cable core. The wrapping layer sleeves the cable core, and the external surface of the wrapping layer is provided with the woven armored layer in a weaving manner. The sheath layer sleeves the woven armored layer. The cable is advantageous in that 1, the tensile strength of the cable is high; 2, the performance of resistance to high temperature is good; 3, the performance of resistance to corrosion is good; 4, the density is low, and the weight is light; 5, the electromagnetic compatibility of the cable is improved; 6, the temperature resistance level and current carrying capability of the cable can be improved.

Description

technical field [0001] The invention relates to the technical field of cable production and processing, in particular to an ultra-light halogen-free low-smoke flame-retardant ship cable. Background technique [0002] The structure of the current ship power cable adopts the following structure, the conductor is tinned conductor, the insulation is cross-linked polyethylene insulation, the filling is filled with glass fiber rope, and the inner sheath is wrapped with glass fiber tape plus extruded low-smoke and halogen-free Flame retardant polyolefin material, then braided tinned copper wire or galvanized steel wire, and finally extruded cross-linked halogen-free low-smoke flame-retardant and oil-resistant polyolefin sheath. In this structure, the fiberglass rope filling material has a high density, which will increase the weight of the cable, and the glass fiber in the glass fiber rope will cause harm to the human body. However, this patent uses foamed low-density flame-retarda...
