Fig. 1 is a schematic view of an underwater cable according to an embodiment of the present utility model.
In the figure: 1-a shielding layer a; 2-a flexible sheath layer; 3-a flexible wire core A; 4-a flexible wire core B; 5-a shielding layer B; 6-Kevlar filler; 7-polyvinyl chloride insulating sheath.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1, the present utility model provides an underwater cable, which includes an outer covering member, a core member, and a kevlar filler 6.
The outer wrapping member comprises a flexible jacket layer 2;
the wire core component comprises a flexible wire core A3 positioned at the center of the flexible sheath layer 2 and a flexible wire core B4 which is designed in an outward circular array by taking the flexible wire core A3 as the center of a circle, and the flexible wire core B4 is also positioned in the flexible sheath layer 2, as shown in figure 1, the number of the flexible wire core B4 designs in the utility model is eight;
the kevlar filler 6 is filled in the flexible sheath layer 2 and is positioned at a gap between the flexible sheath layer 2 and the flexible wire core A3 and the flexible wire core B4, wherein the kevlar filler 6 can increase the softness and the tensile strength of the cable.
The flexible sheath layer 2 is in particular a polyurethane sheath. Wherein. The polyurethane sheath has the characteristics of tensile resistance, wear resistance, seawater corrosion resistance and acid and alkali resistance, namely has a waterproof effect, so that the cable is suitable for underwater operation.
The flexible wire core A3 is formed by four wire cores stranded by pure copper, and the flexible wire core B4 is formed by two wire cores stranded by pure copper. The pure copper stranded wire core has the advantages of strong electromagnetic interference resistance, high elasticity, high foldability and difficult breakage.
The outer walls of the flexible wire core A3 and the flexible wire core B4 are directly extruded with the polyvinyl chloride insulating sheath 7, so that the flexibility is high, and the flexibility of the cable is effectively improved.
The inner wall of the flexible sheath layer 2 is provided with a shielding layer A1, shielding layers B5 are arranged outside polyvinyl chloride insulating sheaths 7 correspondingly connected with the outer walls of the flexible wire cores A3 and each flexible wire core B4, and the shielding layers A1 and B5 are particularly tinned copper shielding layers. The tin-plated copper shielding layer is used for shielding and isolating mutual electric signal interference between twisted wire pairs and interference of external electromagnetic waves on effective signals inside the twisted wire pairs.
The underwater cable is used in the following steps: the inner wire core is composed of a flexible wire core A3 and a flexible wire core B4, and the flexible wire core A3 and the flexible wire core B4 are composed of wire cores stranded by pure copper, so that the cable has the advantages of strong electromagnetic interference resistance, high elasticity, strong foldability and difficult breakage; the outer flexible sheath layer 2 is a polyurethane sheath, has the advantages of tensile resistance, abrasion resistance, seawater corrosion resistance and acid and alkali resistance, and the inner sheath is a polyvinyl chloride insulating sheath 7, so that the flexibility is high, and the flexibility of the cable is effectively improved; the filling structure between the wire core and the outer sheath adopts the Kevlar filling material 6, so that the softness and the tensile strength of the cable can be further increased.
