Embodiment Construction
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0015] see figure 1 , a cable jacket with good waterproof performance, comprising a cable body 1, a cable core 2 is arranged inside the cable body 1, an insulating layer 3 is arranged on the surface of the cable core 2, the insulating layer 3 is wrapped on the surface of the cable core 2, and is insulated The inner surface of the layer 3 is insulated. By setting the insulating layer 3, the insulation performance of the surface of the cable core 2 can be increa...

The invention discloses a cable jacket with good waterproof performance. The cable jacket comprises a cable body; a cable core is arranged in the cable body; an insulating layer is arranged on the surface of the cable core; an anti-static layer is arranged on one side, far from the cable core, of the insulating layer; an inner sheath is arranged on one side, far from the insulating layer, of the anti-static layer; a macromolecule water-blocking layer is arranged on one side, far from the anti-static layer, of the inner sheath; a PVC protection layer is arranged on one side, far from the innersheath, of the macromolecule water-resisting layer; and a protection sleeve is arranged on one side, far from the macromolecule water-resisting layer, of the PVC protection layer. By virtue of settingof the macromolecule water-resisting layer and a waterproof layer, the waterproof performance of the cable jacket can be improved; meanwhile, the cable jacket adopts waterproof design, so that aftera liquid enters the outer sheath, the waterproof material expands due to water to prevent water from further diffusion along the cable jacket, so that a high waterproof effect is played; and meanwhile, the problem of inconvenience in use by people caused by gradual degradation of the waterproof performance can be solved at the same time.
Description
technical field [0001] The invention relates to the technical field of communication cables, in particular to a cable jacket with good waterproof performance. Background technique [0002] In the construction process of communication engineering, it is necessary to add a layer of protective cover on the surface of the cable to protect the cable, and the surface of the communication cable is covered with a highly insulating covering layer. At the same time, the cable has the characteristics of internal energization and external insulation. Some communication cables Laying in inland rivers or on the bottom of the sea requires high waterproof performance. Because there are many fish and shrimps in the river and bottom of the sea, they will bite the cable, and the waterproof performance of the cable jacket will gradually decrease due to the influence of water pressure after long-term use. , making it inconvenient for people to use. Contents of the invention [0003] The objec...
