Embodiment 1

[0044] Embodiment 1 of the present application discloses a high-performance composite cable. refer to figure 1 , The high-performance composite cable includes a cable core 1, a cladding layer 2, a shielding layer 3, an oxygen barrier layer 4, a waterproof layer 5, an armor layer 6 and a sheath layer 7 arranged in sequence from the inside to the outside.

[0045] Among them, the cable core 1 is composed of three single cables 11 and a plurality of filling ropes 12 twisted, the centers of the three single cables 11 are located on the same circumference, and the filling ropes 12 are filled in the gaps around the three single cables 11; the single cables 11 are composed of conductor wires The core is composed of a waterproof insulating layer 112 covering the conductor core. The conductor core is formed by twisting a plurality of conductor monofilaments 111. The waterproof insulating layer 112 is obtained by extruding cross-linked polyethylene. In this embodiment, the conductor mo...

Embodiment 2

[0059] Embodiment 2 of the present application discloses a high-performance composite cable, referring to image 3 The difference from the high-performance composite cable in Example 1 is that the armor layer 6 is composed of steel wire armor, and the side of the moisture-absorbing tube 51 away from the oxygen barrier layer is embedded in the armor layer 6 and formed by adjacent steel wires. In the gap, and the outer diameter of the steel wire of the armor layer 6 is not greater than 2 times of the outer diameter of the moisture-absorbing pipe 51. In this embodiment, the outer diameter of the armored layer 6 steel wire is 2mm, the outer diameter of the moisture-absorbing tube 51 is 1.1mm, and the wall thickness of the moisture-absorbing tube 51 is 0.25mm

[0060] This embodiment 2 also discloses the manufacturing method of the high-performance composite cable in this embodiment. The difference from the manufacturing method of the high-performance composite cable in embodiment ...

Abstract

The invention relates to a high-performance composite cable and a manufacturing method thereof. The high-performance composite cable comprises a cable core, a wrapping tape layer, a shielding layer, a waterproof layer, an armor layer and a sheath layer which are sequentially arranged from inside to outside. The waterproof layer is formed by surrounding moisture absorption pipes, the moisture absorption pipes comprise capillary tubes and super absorbent resin particles in inner cavities of the capillary tubes, and moisture absorption holes are formed in the capillary tubes. The manufacturing method comprises the following steps: extruding a waterproof insulating layer outside the conductive wire core to obtain a single cable, and twisting a plurality of single cables and a filling rope to obtain the cable core; wrapping the outer surface of the cable core with the wrappingtape cloth to form the wrapping tape layer; wrapping with a semiconductor composite belt to form the shielding layer; winding a moisture absorption pipe to form a waterproof layer, arranging an armor layer on the surface of the waterproof layer, and extruding a sheath layer to obtain a finished cable; wherein the moisture absorption pipe is manufactured by blowing and injecting super absorbent resin particles into a thermoplastic pipe, heating and stretching the super absorbent resin particles into capillary tubes, then forming moisture absorption holes, and cooling and shaping the capillary tubes. The high-performance composite cable has the advantage of being good in moisture-proof effect.

Description

technical field [0001] The present application relates to the field of cables, in particular to a high-performance composite cable and a manufacturing method thereof. Background technique [0002] With the rapid development of urbanization and industrialization, both people's daily work and life and industrial production are moving towards electrification. Therefore, cables are used more and more widely as the basis for the use of electrical facilities. [0003] The Chinese invention application with the application number 201510923802.4 discloses a high-performance cable, which includes an outer sheath, an armor layer, an inner sheath, a shielding layer, a filling layer, and several cable cores arranged sequentially from the outside to the inside. The cable core includes a pair of copper wires, and the outside of the pair of copper wires is wrapped with an insulating layer, and resin is filled between the pair of copper wires and the insulating layer; the cable core is arra...
