Abstract
The invention discloses a method for processing a cracked cable. After removing a cracking wire of a three-core cable and the same size of a single core cable is removed from a outer sheath and a outer semiconductor layer, then heat shrinkable treatment carried with a high pressure insulation shrink tube; each cable core of the three-core cable of the cutting cracked wire is docked with a single-core cable which is processed by step two through an intermediate cable joint; the single-core cable which have finished the docking is connected to the corresponding overhead lines. By docking the original cable with the single-core cable, the single-core cable are led to the overhead line. Since the single core cable shrinks the high pressure heat shrinkable tube, the main insulation damage caused by the bad environment is avoided, so a repair of the cracked cable is completed, and a re-cracking of the cable is avoided.

Specific embodiment
The core of the present invention is to provide a kind of processing method of cracking cable, to avoid the phenomenon of cable cracking.
In order that those skilled in the art more fully understands the technical scheme that the present invention provides, below in conjunction with accompanying drawing and
The present invention is described in further detail for specific embodiment.
As depicted in figs. 1 and 2, the processing method of a kind of cracking cable provided in an embodiment of the present invention, including step：
Step 001：The cracking wire of excision three-core cable 1；Need exist for illustrating, those skilled in the art should be able to
It is understood by, before carrying out step 001, also should include preparation of construction work：Safety appliance inspection on such as steel tower, by ferrum
The cable of former cracking at tower is put to ground after removing.Also should include after completing step 001 cable after processing is tested
It is qualified to test whether, then pulls on to steel tower, according to practical situation, the lower floor that can be pulled to steel tower can also be pulled in steel tower
Layer.
Step 002：The single-core cable 2 of same specification is removed after oversheath and outer semiconductor layer, uses High-Voltage Insulation heat-shrink tube
Carry out pyrocondensation process.It should be noted that those skilled in the art should be understood that whole single-core cable contraction of reply is high
The warm draw.It is further to note that the order of step 001 and step 002 can overturn.
Step 003：By excision cracking wire three-core cable 1 every core cable respectively with the single processing through step 2
Cable 2 docks；Docking can be docked using cable intermediate joint, or other docking modes that those skilled in the art commonly use
Docked.
Step 004：Single-core cable 2 after completing to dock is connected with corresponding aerial line 3.
Compare and introduce content with background technology, the processing method of the cable that is cracked in technique scheme, by by former cable
Dock with single-core cable, then single-core cable is caused on aerial line, the high pressure heat-shrink tube due to single-core cable contraction, and then avoid
Because of the damage of the major insulation that adverse circumstances lead to, while the reparation problem of the cable that therefore completes to be cracked, avoid cable again
Cracking.
In some specific embodiments, above-mentioned single-core cable 2 is to carry out from bottom to top with the order of connection of aerial line 3
Connect.Of course, it should be understood that above-mentioned be attached from bottom to top only the embodiment of the present invention for single-core cable 2 and frame
A kind of citing of the order of connection of ceases to be busy 3, can also be according to top-down mode of actual installation situation etc..
In a more particular embodiment, above-mentioned single-core cable 2 passes through screw bolt-type TLS two-conductor line with corresponding aerial line 3
Downlead T ramp 4 connects.It is appreciated of course that above-mentioned screw bolt-type TLS two-conductor line downlead T ramp 4 only connects
It is that a kind of of the embodiment of the present invention preferably illustrates, can also be general T ramp.
In technique scheme, aerial line 3 can be conventional other in double bundle conductor or distribution line
Wire.Specifically, it is also provided with conductor spacer 5 between this double bundle conductor.Further ensured point by arranging conductor spacer
Split line and be in Separation state.
In some specific embodiments, the end that single-core cable 2 is connected with corresponding aerial line 3 is also crimped with nose
Son.Need exist for illustrating, those skilled in the art should be understood that the nose of crimping is tied for the terminal that one end blocks
Structure.The end avoiding end by crimping nose is invaded by rainwater, in order to reduce rainwater or moisture to greatest extent to electricity
The impact of cable end, nose is gone back contraction high pressure heat-shrink tube, and on nose, the high pressure heat-shrink tube of contraction is located at single electricity in step 2
Cable carries out the outside of the high pressure heat-shrink tube of contraction when pyrocondensation is processed, and that is, high pressure heat-shrink tube in top is set in outside the high heat-shrink tube of bottom
Face, and then avoid due to high pressure heat-shrink tube joint not consolidation or have gap etc. to cause the intrusion of top-down rainwater.
More specifically in implementation process, at above-mentioned nose high pressure heat-shrink tube opening upward, it is also coated with fluid sealant.By close
Sealing carries out sealing and is further ensured that sealing to the opening of high pressure heat-shrink tube, places the erosion of the liquid such as rainwater.Further
In embodiment, through coating after fluid sealant at above-mentioned nose high pressure heat-shrink tube opening upward, also carry out through high pressure PUR
Sealing treatment, is further ensured that sealing.
