Description
Technical field
The utility model is related to the technical field of cable, specifically a kind of water blocking overhead insulated cable.
Background technology
At present, the researching and analysing for cable fault with people, it is found that water tree phenomenon has greatly to medium and high voltage cable
Harm, has become increasingly aware of the importance that cable insulation waterproof is particularly axial waterproof.
And cable waterproof work of the prior art, surface waterproofing is typically only laid particular emphasis on, i.e., how to prevent water from penetrating into cable
Inside, when once there is water to penetrate into, then cannot be internally formed effectively resistance section layer by layer in cable, cause water tree phenomenon, cable is produced
Raw high risks, shorten the service life of cable.
Content of the invention
The purpose of this utility model is to provide a kind of improved water blocking overhead insulated cable, and it can be overcome in prior art
The not good some shortcomings of waterproof, block-water effect.
To achieve these goals, the technical solution of the utility model is：A kind of water blocking overhead insulated cable, its feature exist
In：Described insulated cable includes compact conductor layer, the water blocking layer being embedded in conductor layer；It is enclosed with outside compact conductor layer successively
Internal shield and insulating barrier.
Preferably, described compact conductor layer is divided into five layers from inside to outside, be respectively 1 conductor layer, 6 conductor layers, 12
Root conductor layer, 18 conductor layers and 23 conductor layers.
Further, first block water layer between a conductor layer and 6 conductor layers；6 conductor layers and 12 conductor layers it
Between be provided with the first water blocking tape layer；It is provided with second to block water layer between 12 conductor layers and 18 conductor layers, 18 conductor layers and 23
The second water blocking tape layer is provided between root conductor layer.
Further, described compact conductor presses aluminium conductor using circle and makes, and presses coefficient for 0.89.
During use, compact conductor layer of the utility model using feature, described compact conductor layer are divided into from inside to outside
Five layers, each layer of number of conductors is different, between layers by block water layer and water blocking tape layer formed layer by layer closed loop around
Effect, reach the optimal purpose that blocks water so that in each pitch of conductor, forms single closed loop, it is ensured that axially anti-
Water, the purpose for blocking water, improve the service life of cable.
Description of the drawings
Structural representations of the Fig. 1 for one embodiment of the utility model.
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
Label in accompanying drawing is expressed as follows：
1 conductor, 2 first block water layer, 3 first water blocking tape layers, 4 second block water layer, 5 second water blocking tape layers, 6 inner shields
Layer, 7 insulating barriers.
A kind of water blocking overhead insulated cable described in the utility model, its difference with the prior art are：Described is exhausted
Edge cable includes compact conductor layer, the water blocking layer being embedded in conductor layer；Be enclosed with outside compact conductor layer successively internal shield and
Insulating barrier.
Preferably, described compact conductor layer is divided into five layers from inside to outside, be respectively 1 conductor layer, 6 conductor layers, 12
Root conductor layer, 18 conductor layers and 23 conductor layers.A conductor layer described here refers to and is made up of a conductor, 6 conductors
Layer is then formed around the arrangement of an above-mentioned conductor layer by 6 conductors, the like, final outer layer is 23 conductor layers.
Further, first block water layer between a conductor layer and 6 conductor layers；6 conductor layers and 12 conductor layers it
Between be provided with the first water blocking tape layer；It is provided with second to block water layer between 12 conductor layers and 18 conductor layers, 18 conductor layers and 23
The second water blocking tape layer is provided between root conductor layer.Blocked water by such water blocking tape layer and the layer alternating that blocks water and arranged so that layer
Between layer by block water layer and water blocking tape layer formed closed loop layer by layer around effect, reach the optimal purpose that blocks water so that
Single closed loop is formed in each pitch of conductor, it is ensured that axial waterproof, the purpose for blocking water, improve the use of cable
Life-span.
Optionally, described compact conductor presses aluminium conductor using circle and makes, and presses coefficient for 0.89.Inner shield is adopted
Cross-linking type semiconductive shieldin material is made, and insulation is made using the weather-proof cross-linking type overhead insulating materials of 25KV, and the thickness of internal shield is
0.3-0.7mm, the thickness of insulating barrier is 4-5mm.
In enforcement, conductor strand presses aluminium conductor using circle, presses coefficient 0.89, and conductor structure is closely knit, same conductor
Under sectional area, press rear conductor diameter and reduce 10% or so, so as to reduce the gap between monofilament.This product sectional area 300mm2,
Using the monofilament of 60 2.58mm, divide five layers from inside to outside, be 1 layer respectively, 6 layers, 12 layers, 18 layers, 23 layers are adopted
With regular stranded.In order that conductor axially can block water, while compact conductor, per layer adds water blocking yarn or waterstop, resistance
Water yarn or waterstop are expanded after meeting water rapidly, prevent water from permeating toward conductor so as to play, so as to play the purpose for blocking water.Interior
Shielding average thickness 0.5mm, insulate average thickness 4.5mm, product mean outside diameter 30.6mm.Inner shield adopts cross-linking type semiconductive
Shielding material, insulation are extruded using fashion of extrusion, extruded material is closely coated on using the weather-proof cross-linking type overhead insulating materials of 25KV
On conductor, so as to play the purpose for blocking water.
Above content is with reference to specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the utility model is embodied as being confined to these explanations above-mentioned.Common skill for the utility model art
For art personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should
It is considered as belonging to protection domain of the present utility model.
