Abstract
The invention provides a kind of low-voltage cable transition joint method, first thermal contraction type plastic cable is worn on the cable of any side, overlap another side cable, the cable core of cable is crimped including conductor using conductor casing, then three layers of overlap wrapping fire-resistant isinglass belt outside cable joint-box, using the insulating materials crosslinking with radiation heat shrink films of material of the same race, finally crosslinking with radiation heat shrink films are heated, crosslinking with radiation heat shrink films are molded.The present invention is with low cost, easy to operate, safe.
Description
Technical field
The present invention relates to field of cables, specifically a kind of low-voltage cable transition joint method.
Background technology
During the actual production of cable and use, the actual rice number that enterprise produces a cable can not possibly be unrestricted
Length, exist in laid processes cable damage cause segmentation, it is therefore desirable to do cable intermediate joint, at present make cable in the middle of
The cost of joint is higher, causes construction party to make the insecurity that transition joint is simply used.
The content of the invention
The present invention in order to solve problem of the prior art there is provided one kind it is with low cost, in easy to operate low-voltage cable
Between jointing method, it is safe.
The present invention comprises the following steps：
1）Thermal contraction type plastic cable is worn on the cable of any side, another side cable is overlapped, the cable core of cable includes leading
Body is crimped using conductor casing, and conductor casing size is identical with the nominal section of cable；
2) three layers of overlap wrapping fire-resistant isinglass belt outside cable joint-box, use the insulating materials crosslinking with radiation thermal contraction of material of the same race
Film, winding insulation thickness is 1.1-1.2 times of nominal thickness；
3）Crosslinking with radiation heat shrink films are heated, crosslinking with radiation heat shrink films are molded, hard-pressed bale conductor, further around one layer of marine glue of bag
Band.
Step 1）Described cable bond process is specially：First overlap between core, any two joint at least distance
20 centimeters, after many insulated wire cores are repaired, packed tightly using adhesive tape, reuse non-woven fabrics and tighten, form cable core.
Step 3）Described crosslinking with radiation heat shrink films forming method is specially：Coat after crosslinking heat shrink films, use
High temperature resistant clad strip is overlapping around double-baging, overlapping around double-baging further around bag glass fiber band, then overlapping wrapped 0.10mm copper
Two layers of band, by heating, heating-up temperature sets about 140 DEG C, about 5-8 minutes time, is cooled to normal temperature using cold water, removes copper
Band, glass fiber band, high temperature resistant clad strip polishes flat insulated wire cores surface treatment.
If having armor outside cable, armor is connected using braided metal bar, then by cable thermal contraction type plastics
Sleeve pipe is heated in mend, is tightly covered to plastic shrink on cable, and seam crossing uses wrapped one layer of adhesive waterproof tape, plays waterproof
Effect.
Beneficial effect of the present invention is：It is with low cost, it is easy to operate, it is safe.
Embodiment
The invention provides a kind of low-voltage cable transition joint method, comprise the following steps：
1）Thermal contraction type plastic cable is worn on the cable of any side, another side cable is overlapped, the cable core of cable includes leading
Body is crimped using conductor casing, and conductor casing size is identical with the nominal section of cable；
2) three layers of overlap wrapping fire-resistant isinglass belt outside cable joint-box, use the insulating materials crosslinking with radiation thermal contraction of material of the same race
Film, winding insulation thickness is 1.1-1.2 times of nominal thickness；
3）Crosslinking with radiation heat shrink films are heated, crosslinking with radiation heat shrink films are molded, hard-pressed bale conductor, further around one layer of marine glue of bag
Band.
Step 1）Described cable bond process is specially：First overlap between core, any two joint at least distance
20 centimeters, after many insulated wire cores are repaired, packed tightly using adhesive tape, reuse non-woven fabrics and tighten, form cable core.
Step 3）Described crosslinking with radiation heat shrink films forming method is specially：Coat after crosslinking heat shrink films, use
High temperature resistant clad strip is overlapping around double-baging, overlapping around double-baging further around bag glass fiber band, then overlapping wrapped 0.10mm copper
Two layers of band, by heating, heating-up temperature sets about 140 DEG C, about 5-8 minutes time, is cooled to normal temperature using cold water, removes copper
Band, glass fiber band, high temperature resistant clad strip polishes flat insulated wire cores surface treatment.
If having armor outside cable, armor is connected using braided metal bar, then by cable thermal contraction type plastics
Sleeve pipe is heated in mend, is tightly covered to plastic shrink on cable, and seam crossing uses wrapped one layer of adhesive waterproof tape, plays waterproof
Effect.
Cable intermediate joint means of defence is as follows：
1st, repair place uses groove mode, and gash depth is according to environmental requirement, some sands of pre-fill in groove, treat cable be put into
Afterwards, the cable in groove is covered using sand, at least beyond cable surface 10Ccm, covers cover plate.
2nd, protected using steel pipe, when it needs to make cable connector again, in advance by cable through in steel pipe, the internal diameter of steel pipe is extremely
It is 2 times of cable less, and prevents steel pipe from sinking, some sands need to will be filled out in groove.
Concrete application approach of the present invention is a lot, and described above is only the preferred embodiment of the present invention, it is noted that for
For those skilled in the art, under the premise without departing from the principles of the invention, some improvement can also be made, this
A little improve also should be regarded as protection scope of the present invention.
