Abstract
The utility model discloses a kind of water resistant tree crosslinked polyethylene insulation material cable, ecto-entad includes outer jacket, water blocking layer successively, insulated wire cores are provided with water blocking layer, the gasket for packing that blocks water is provided between insulated wire cores, moisture-proof layer is provided with water blocking layer, the material of moisture-proof layer is metal composite bag, and moisture-proof layer is internally provided with metal armor layers, is provided with the gasket for packing that blocks water in metal armor layers；This utility model is arranged on moisture-proof layer in water blocking layer, it is to avoid moisture-proof layer is directly contacted with outer jacket, reduces and changes skin problem because temperature is too high and caused under the influence of external environment or event of overload.Metal armouring, so that moisture-proof layer material directly will not be contacted with the gasket for packing that blocks water, so as to moisture-proof layer be caused to fail because loose, this utility model is converted by simple technology, cable is enabled effectively to prevent water inlet in cable, even if also water tree will not be produced in cable insulation after water inlet.
Description
Technical field
This utility model is related to a kind of cable, specifically a kind of water resistant tree crosslinked polyethylene insulation material cable.
Background technology
To disclose one kind water resistant tree crosslinked polyethylene that blocks water entirely exhausted for the patent documentation of CN201069676Y for Authorization Notice No.
Edge power cable, structure are by water-blocking conductor 1, internal shield 2, insulating barrier 3, the resistance of external shielding layer 4, semiconductive from inside to outside successively
Block water outer layer 7, radial direction moisture-proof layer 8 and outer jacket 9 of water internal layer 5, metal screen layer 6, semiconductive is constituted；Three-core structure is by three
After insulated wire cores 10 and 11 twisted synthesizing cable of gasket for packing that blocks water, outer layer is water blocking layer 12, radial direction moisture-proof layer 8 ', 9 ' group of outer jacket successively
It is to be formed by many single metal wires 13 are stranded into, water-blocking conductor 1, it is wrapped absolutely in the stranded overlap between layers of single metal wire 13
Edge waterstop 14.This utility model adopts the mode that longitudinally and radially blocks water by conductor, insulant, the construction of cable, so as to have
Effect suppress crosslinked cable in use moisture immersion and insulation in water tree generation, significant reduction crosslinked cable failure
Rate, provides a kind of New Type of Cable Products for wires and cables industry.
This structure, when easily moisture-proof layer skin is caused because temperature is too high under external environment or event of overload, no
Moisture-proof layer failure is only resulted in, can also connect electricity because of the change skin of moisture-proof layer.
Utility model content
The purpose of this utility model is to provide a kind of water resistant tree crosslinked polyethylene insulation material cable, and the cable effectively can be prevented
Water tree is produced in cable after water inlet, and water inlet in cable insulation only.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is：
A kind of water resistant tree crosslinked polyethylene insulation material cable, ecto-entad include outer jacket, water blocking layer, the resistance successively
Insulated wire cores are provided with water layer, the gasket for packing that blocks water between the insulated wire cores, is provided with, the insulated wire cores ecto-entad is successively
Block water internal layer, external shielding layer, insulating barrier, internal shield and water-blocking conductor including metal screen layer semiconductive, in the water blocking layer
Moisture-proof layer is provided with inside, the material of the moisture-proof layer is metal composite bag, the moisture-proof layer is internally provided with metal armor layers,
The gasket for packing that blocks water is provided with metal armor layers.
Preferably, the material of the moisture-proof layer is composite steel-plastic belt.Metal armor layers are zinc-plated copper wire armored
This utility model is arranged on moisture-proof layer in water blocking layer, it is to avoid moisture-proof layer is directly contacted with outer jacket, is reduced
Change skin problem because temperature is too high and caused under the influence of external environment or event of overload.On the other hand, in moisture-proof layer
The metal armouring of setting so that moisture-proof layer material directly will not be contacted with the gasket for packing that blocks water, so as to gear will not be caused because loose
Damp layer failure, it is seen that electromagnetic shielding and mechanical protection are not only played a part of in metal armouring.This utility model is by simple
Technology is converted so that cable can effectively prevent water inlet in cable, even if also water tree will not be produced in cable insulation after water inlet.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in further detail.
As shown in figure 1, a kind of water resistant tree crosslinked polyethylene insulation material cable, ecto-entad is successively including outer jacket 1, resistance
Water layer 2, moisture-proof layer 3, metal armor layers 4 are provided with insulated wire cores 12 in metal armor layers 4, arrange between the insulated wire cores 12
Block water gasket for packing 5, and 12 ecto-entad of the insulated wire cores is blocked water internal layer 7, external screen including metal screen layer 6, semiconductive successively
Cover layer 8, insulating barrier 9, internal shield 10 and water-blocking conductor 11.The material of insulating barrier 9 selects the crosslinked polyetylene insulated material of water resistant tree
Material.
The material of the moisture-proof layer 3 be metal composite bag, preferred composite steel-plastic belt；The metal armor layers 4 are TC
Silk armouring, metal armouring play electromagnetic shielding and mechanical protection act on while so that moisture-proof layer material will not directly with resistance
Water gasket for packing is contacted, so as to moisture-proof layer be caused to fail because loose.
Above-described embodiment limits this utility model never in any form, every by the way of equivalent or equivalent transformation
The technical scheme of acquisition is all fallen within protection domain of the present utility model.
