For achieving the above object, the technical solution of the utility model is as follows:
A kind of crosslinked polyetylene insulated phase-splitting water-proof cable that blocks water, comprises at least one core and is arranged on the aluminium sheath in described core outside, between described core and described aluminium sheath, is provided with rubber filling layer.
Polyethylene water blocking layer, water sucting belt and polyethylene inner sheath that described core comprises conductor and sets gradually from the inside to the outside in described conductor outside.
Described conductor comprises wire, water blocking yarn and semi-conductive layer, and described water blocking yarn is together with described wire stranding, and described semi-conductive layer is extruded in the outside of described wire and described water blocking yarn.
Preferably, between described semi-conductive layer and described polyethylene water blocking layer, be provided with successively from the inside to the outside conductor shield and insulating barrier, between described polyethylene water blocking layer and described water sucting belt, be provided with plastic anti-corrosion layer.
Preferably, described aluminium sheath outside is coated with outer protective polyethylene cover.
Preferably, described core is three.
Pass through technique scheme, the crosslinked polyetylene insulated phase-splitting of one that the utility model the provides water-proof cable that blocks water is realized footpath phase waterproof by polyethylene water blocking layer, water sucting belt, aluminium sheath, polyethylene inner sheath, outer protective polyethylene cover also has the effect of footpath phase waterproof, realize longitudinal phase waterproof by water blocking yarn and rubber filling layer, can, exceeding under the prerequisite that increases production cost, significantly promote the water resistance of cable.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
According to Fig. 1, the utility model provides a kind of crosslinked polyetylene insulated phase-splitting water-proof cable that blocks water, comprise three cores (1) and be arranged on the aluminium sheath (2) in core outside, aluminium sheath outside is coated with outer protective polyethylene cover (3), is filled with rubber filling layer (4) between core and aluminium sheath.
Rubber filling layer adopts the rubber sleeve of extrusion molding in advance in conjunction with blocking water stranding of band, and outside adopts argon arc welding welding of aluminum sheath, finally extrudes outer protective polyethylene cover at aluminium sheath skin.
Aluminium sheath adopts contrast corrugated aluminum sheath argon arc welding solder technology to manufacture, this solder technology be under the protection of argon gas and helium taking aluminium sheet as negative pole, tungsten electrode be anodal, by low-voltage, electric current completes welding greatly.Tungsten electrode soldering tip only has the diameter of 2mm, and blows to continuously solder joint place by protective gas, takes away rapidly heat, makes welding position evenly cooling fast, and in welding process, the construction of cable can not be subject to any harmful effect, has also avoided the high-temperature oxydation of aluminium sheath simultaneously.Compare with traditional aluminium sheath technology that extrudes, use contrast corrugated aluminum sheath argon arc welding solder technology little to core damage, the cable machinery excellent performance of processing.
According to Fig. 2, conductor shield (1-2), insulating barrier (1-3), polyethylene water blocking layer (1-4), plastic anti-corrosion layer (1-5), water sucting belt (1-6) and polyethylene inner sheath (1-7) that core comprises conductor (1-1) and sets gradually from the inside to the outside in conductor outside.
Extrude one deck outward by the made conductor shield of high density polyethylene (HDPE) carbon black composite conducting ptc material at conductor, utilize its material under the irradiation of electromagnetic field of high frequency, because of poorly conductive, molecule is not substantially by electromagnetic field effects, also little characteristic of its electromagnetic field of high frequency energy loss, realizes the electromagnetic shielding of conductor.
Insulating barrier adopts crosslinked polyetylene insulated, extrudes polyethylene water blocking layer outward at insulating barrier, and at polyethylene water blocking layer outer wrapping plastic anti-corrosion layer, wrapped water sucting belt outside plastic anti-corrosion layer, finally extrudes polyethylene inner sheath again and form core.
According to Fig. 3, conductor comprises wire (1-1-1), water blocking yarn (1-1-2) and semi-conductive layer (1-1-3), and water blocking yarn is together with wire stranding, and semi-conductive layer is extruded in the outside of wire and water blocking yarn.In stranded copper wires process, add and adopt the middle water blocking yarn that adds water absorbent polymer of double-deck base cloth, be difficult to the characteristic in copper conductor surface attachment compared to water-proofing powder, water blocking yarn more can effectively be filled in the space of wire.
Semi-conductive layer can fixed conductor shape, can also prevent that electric field deterioration from appearring in cable in transport or work progress because of flexural deformation, cause the phenomenon of bubble-discharge insulation breakdown.
The crosslinked polyetylene insulated phase-splitting of one that the utility model the provides water-proof cable that blocks water is realized footpath phase waterproof by polyethylene water blocking layer, water sucting belt, aluminium sheath, polyethylene inner sheath, outer protective polyethylene cover also has the effect of footpath phase waterproof, realize longitudinal phase waterproof by water blocking yarn and rubber filling layer, and waterproof and the effective combination of mechanical performance, can, exceeding under the prerequisite that increases production cost, significantly promote the water resistance of cable.
To the block water above-mentioned explanation of water-proof cable embodiment of disclosed a kind of crosslinked polyetylene insulated phase-splitting, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
