Problems solved by technology

[0004] However, the water-blocking performance of the water-blocking cable plays a vital role in whether it can operate normally in water. However, the existing water-blocking cables still have certain deficiencies in the water-blocking performance. The water-blocking performance must be weakened when the water is waterproof. Therefore, a new type of water-blocking cable is needed to improve the weakness of the water-blocking performance of the existing water-blocking cables.

Embodiment 1

[0046] Interlocking armored water-blocking cable

[0047] Such as figure 1 As shown, the interlocking armored water-blocking cable includes: cable core 1 with 3 water-blocking cores twisted into a cable, water-blocking tape 2 covering cable core 1, water-blocking tape 2 and water-blocking core Composite water-blocking material is filled in between, the first water-blocking yarn 3 wrapped on the outer surface of the water-blocking tape 2, and the armor layer 4 wrapped on the outer surface of the first water-blocking yarn 3, wrapped on the armor layer 4 the second water-blocking yarn 5 on the outer surface, and the outer sheath 6 covered on the outer surface of the second water-blocking yarn 5, the water-blocking tape 2 is a commercially available water-blocking tape, the first water-blocking yarn 3, the second water-blocking Water yarn 5 is a commercially available water blocking yarn;

[0048] Among them, such as figure 2 As shown, the water blocking core is wrapped with c...

Embodiment 2

[0071] This embodiment is basically the same as Embodiment 1, except that the combination of composite water-blocking materials is different, specifically:

[0072] The composite water-blocking material mainly consists of: 30 parts of superabsorbent resin particles, 5 parts of hydrated magnesium silicate superfine powder, 2 parts of anhydrous copper sulfate fine powder, and 10 parts of palygorskite fine powder in parts by weight, wherein , the particle size of the hydrated magnesium silicate ultrafine powder is 0.8 μm, the particle size of the anhydrous copper sulfate fine powder is 1.2 μm, and the mesh number of the palygorskite fine powder is 110 mesh. The composite water-blocking material prepared by formulating the above-mentioned proportioning components not only has higher fluidity, but also has strong water absorption, which can be well applied to the special aluminum alloy strip 41 of the armor layer 4. At the same time, due to its It has better fluidity and can be use...

Embodiment 3

[0074] This embodiment is basically the same as Embodiment 1, except that the combination of composite water-blocking materials is different, specifically:

[0075]The composite water-blocking material is mainly composed of: 50 parts of superabsorbent resin particles, 9 parts of hydrated magnesium silicate superfine powder, 4 parts of anhydrous copper sulfate fine powder, and 20 parts of palygorskite fine powder in parts by weight. , the particle size of the hydrated magnesium silicate ultrafine powder is 0.8 μm, the particle size of the anhydrous copper sulfate fine powder is 1.2 μm, and the mesh number of the palygorskite fine powder is 110 mesh. The composite water-blocking material prepared by formulating the above-mentioned proportioning components not only has higher fluidity, but also has strong water absorption, which can be well applied to the special aluminum alloy strip 41 of the armor layer 4. At the same time, due to its It has better fluidity and can be used as a...

Abstract

The invention discloses a method for preparing an interlocking armored water-blocking cable based on a composite water-blocking material, comprising: S1 preparing a composite water-blocking material for use; S2 prefabricating a water-blocking wire core for use; S3 pre-pressing a special aluminum alloy tape After forming an S shape, a special aluminum alloy belt is prefabricated by a special device for use; S4 twists multiple water-blocking cores into a cable, and wraps multiple water-blocking cores with a water-blocking tape, and the water-blocking tape and the water-blocking core Composite water-blocking material is filled in between, the outer surface of the S5 water-blocking tape is wrapped with the first water-blocking yarn, the outer surface of the first water-blocking yarn is covered with the armor layer, and the outer surface of the armor layer is covered with the second water-blocking yarn in turn. The water yarn and the outer sheath, and the outer surface of the outer sheath is covered with a super-hydrophobic surface to obtain an interlocking armored water-resistant cable. The invention utilizes the structural design of the special aluminum alloy strip and the composite water-blocking material, so that the wrapped armor layer not only has the protection of the cable structure but also has a certain water-blocking performance, thereby improving the water-blocking performance of the water-blocking cable.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a method for preparing an interlocking armored water-blocking cable based on a composite water-blocking material. Background technique [0002] With the large-scale use of cross-linked cables, the accidents of insulation water tree aging and cable breakdown due to the infiltration of moisture in the surrounding environment into the cable are increasing year by year. More and more users are in urgent need of a cable with good water resistance. So water-blocking cables came into being. [0003] Water-blocking cables generally add water-blocking powder and water-blocking yarn between the monofilaments of the stranded conductor during the single-filament twisting process. With further penetration, it can maintain normal operation in water for a long time, effectively ensuring the safety performance of insulation and electricity use. [0004] However, the water-blocking performance o...
