Abstract
The invention belongs to power safety technique fields, more particularly to a kind of cable laying waterproof method.Water-inlet-proof pretreatment is carried out to cable end end before cable waterproof by this method, good water-proof effect extends the service life of cable.
Description
Technical field
The invention belongs to power safety technique fields, more particularly to a kind of cable laying waterproof method.
Background technology
Currently, the production and application of cross-linked power cable product have nearly 30 years history.It has in dry environments
Have excellent electrically and mechanically performance, but in practical applications, precautionary measures are inadequate when due to cable laying, cause cable into
Water makes moist, and the insulating materials of cable body can gradually absorb the moisture in environment.When operation, under the action of electric field, long
And long meeting causes a large amount of water tree in cable insulation, water-treeing makes insulating polymer crack.When water tree reaches in insulation
When saturation state, insulation electrical and mechanical performance will drastically decline, and a large amount of electric energy can be lost in conductive water tree, and finally causes
Cable insulation punctures, to greatly reduce cable service life.
Invention content
Corresponding countermeasure has been formulated for its main influencing factor：Cable end end is prevented before cable waterproof
Into water pretreatment.The present invention proposes that a kind of cable laying waterproof method, good water-proof effect extend the service life of cable.
The technical scheme is that；A kind of cable laying waterproof method, includes the following steps；
S1：At the 50-60cm of cross-linked power cable end, cable jacket, steel armour and copper shield are divested, then in cable
Head divests inner sheath, semiconductor and cable core insulating layer at 10cm backward；
S2：The three-phase cable core of stripping is covered into ear of reaching the standard grade respectively, and is compressed using Press Plier, and online ear end, root and cable core
It at insulated combination and oversheath opening, is sealed using marine glue, prevents water and moisture from penetrating into；
S3：Covering upper heat-shrink tube respectively outside the threephase cable for being pressed with line ear, pyrocondensation tightening is used in combination PVC bands by cable core bundled fixed,
End oversheath is put on, entire end is fastened and is sealed with adhesive waterproof tape, PVC bands；
S4：Upper wire sets are covered on end, you can carry out cable pulling laying.
The above method, cable laying is used to complete by the project under construction for bad environments of paddling in multiple cable layings
Afterwards, the pretreated end of prior progress waterproof is blocked and split analysis, find the end adhesive waterproof tape after splitting
Excellent, three-phase core ear non-loosening, Waterproof glue line is without falling off, and cable copper core is without water inlet.Obviously, to electricity when cable laying
Cable-end portion end carries out the pretreated cable of waterproof, and waterproof is with obvious effects after laying, and cable laying is had into water problems
Effect solves.
The beneficial effects of the invention are as follows；By using above-mentioned side in the project cable laying of multiple bad environments of paddling
Method finds that the waterproof method and step are effective methods, has realized cross-linked power cable substantially in laid processes
Control water inlet, has reached good construction effect.It can be supplemented and be incorporated in cable laying job instruction, promote and answer
With.
Specific implementation mode
Only for illustration, it should not be understood as the limitation to this patent；In order to more preferably illustrate the present embodiment, certain portions
Part has omission, zooms in or out, and does not represent the size of actual product；To those skilled in the art, certain known
Structure and its explanation, which may be omitted, will be understood by.It describes position relationship only for illustration, should not be understood as to this
The limitation of patent.
Embodiment 1：
A kind of cable laying waterproof method, includes the following steps；
S1：At the 50-60cm of cross-linked power cable end, cable jacket, steel armour and copper shield are divested, then in cable
Head divests inner sheath, semiconductor and cable core insulating layer at 10cm backward；
S2：The three-phase cable core of stripping is covered into ear of reaching the standard grade respectively, and is compressed using Press Plier, and online ear end, root and cable core
It at insulated combination and oversheath opening, is sealed using marine glue, prevents water and moisture from penetrating into；
S3：Covering upper heat-shrink tube respectively outside the threephase cable for being pressed with line ear, pyrocondensation tightening is used in combination PVC bands by cable core bundled fixed,
End oversheath is put on, entire end is fastened and is sealed with adhesive waterproof tape, PVC bands；
S4：Upper wire sets are covered on end, you can carry out cable pulling laying.
The above method, cable laying is used to complete by the project under construction for bad environments of paddling in multiple cable layings
Afterwards, the pretreated end of prior progress waterproof is blocked and split analysis, find the end adhesive waterproof tape after splitting
Excellent, three-phase core ear non-loosening, Waterproof glue line is without falling off, and cable copper core is without water inlet.Obviously, to electricity when cable laying
Cable-end portion end carries out the pretreated cable of waterproof, and waterproof is with obvious effects after laying, and cable laying is had into water problems
Effect solves.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
All any modification, equivalent and improvement etc., should be included in the claims in the present invention made by within the spirit and principle of invention
Protection domain within.
