Abstract
The present invention provides a kind of low-voltage cable transition joint methods, first thermal contraction type plastic cable is worn on the cable of any side, overlap another side cable, the cable core of cable includes that conductor is crimped 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, form crosslinking with radiation heat shrink films.The present invention is low in cost, easy to operate, highly-safe.
Description
Technical field
The present invention relates to field of cables, specifically a kind of low-voltage cable transition joint method.
Background technique
In the actual production of cable and use process, the practical rice number that enterprise produces a cable can not be without limitation
Length, damaging in laid processes there are cable causes to be segmented, it is therefore desirable to do cable intermediate joint, at present make cable among
The cost of connector is relatively high, the insecurity for causing construction party production transition joint simply to use.
Summary of the invention
The present invention in order to solve problems in the prior art, provide it is a kind of low in cost, in easy to operate low-voltage cable
Between jointing method, it is highly-safe.
The present invention the following steps are included:
1) thermal contraction type plastic cable is worn on the cable of any side, overlaps another side cable, the cable core packet of cable
It includes conductor to crimp using conductor casing, conductor casing size is identical as the nominal section of cable；
2) three layers of overlap wrapping fire-resistant isinglass belt outside cable joint-box are received using the insulating materials crosslinking with radiation heat of material of the same race
Contracting film, winding insulation thickness are 1.1-1.2 times of nominal thickness；
3) crosslinking with radiation heat shrink films are heated, forms crosslinking with radiation heat shrink films, hard-pressed bale conductor is anti-further around one layer of packet
Glue band.
Cable bond process described in step 1) specifically: first overlap core, equal at least distance between any two connector
It 20 centimeters, after a plurality of insulated core is repaired, is packed tightly using adhesive tape, reuses non-woven fabrics and tighten, form cable core.
Crosslinking with radiation heat shrink films forming method described in step 3) specifically: after coating crosslinking heat shrink films, use
The overlapping of high temperature resistant clad strip is overlapped around double-baging further around packet glass fiber band around double-baging, is then overlapped wrapped 0.10mm copper
Two layers of band, by heating, heating temperature is arranged about 140 DEG C, the time about 5-8 minutes, is cooled to room temperature using cold water, removes copper
Band, glass fiber band, high temperature resistant clad strip polish flat insulated wire cores surface treatment.
If there is armor outside cable, armor is connected using braided metal item, then by cable thermal contraction type plastics
Casing is heated in mend, until seam crossing uses wrapped one layer of adhesive waterproof tape on the fixed cable of plastic shrink, plays waterproof
Effect.
The beneficial effects of the invention are that: it is low in cost, it is easy to operate, it is highly-safe.
Specific embodiment
The present invention provides a kind of low-voltage cable transition joint methods, comprising the following steps:
1) thermal contraction type plastic cable is worn on the cable of any side, overlaps another side cable, the cable core packet of cable
It includes conductor to crimp using conductor casing, conductor casing size is identical as the nominal section of cable；
2) three layers of overlap wrapping fire-resistant isinglass belt outside cable joint-box are received using the insulating materials crosslinking with radiation heat of material of the same race
Contracting film, winding insulation thickness are 1.1-1.2 times of nominal thickness；
3) crosslinking with radiation heat shrink films are heated, forms crosslinking with radiation heat shrink films, hard-pressed bale conductor is anti-further around one layer of packet
Glue band.
Cable bond process described in step 1) specifically: first overlap core, equal at least distance between any two connector
It 20 centimeters, after a plurality of insulated core is repaired, is packed tightly using adhesive tape, reuses non-woven fabrics and tighten, form cable core.
Crosslinking with radiation heat shrink films forming method described in step 3) specifically: after coating crosslinking heat shrink films, use
The overlapping of high temperature resistant clad strip is overlapped around double-baging further around packet glass fiber band around double-baging, is then overlapped wrapped 0.10mm copper
Two layers of band, by heating, heating temperature is arranged about 140 DEG C, the time about 5-8 minutes, is cooled to room temperature using cold water, removes copper
Band, glass fiber band, high temperature resistant clad strip polish flat insulated wire cores surface treatment.
If there is armor outside cable, armor is connected using braided metal item, then by cable thermal contraction type plastics
Casing is heated in mend, until seam crossing uses wrapped one layer of adhesive waterproof tape on the fixed cable of plastic shrink, plays waterproof
Effect.
Cable intermediate joint means of defence is as follows:
1, repair place uses groove mode, and trench depth according to environmental requirement, put to cable by some sands of pre-fill in groove
After entering, the cable in groove is covered using sand, at least exceeds cable surface 10Ccm, covers cover board.
2, it is protected using steel pipe, when needing to make cable connector again, in advance by cable through in steel pipe, the internal diameter of steel pipe is extremely
Less it is 2 times of cable, and prevents steel pipe from sinking, some sands need to will be filled out in groove.
There are many concrete application approach of the present invention, the above is only a preferred embodiment of the present invention, it is noted that for
For those skilled in the art, without departing from the principle of the present invention, it can also make several improvements, this
A little improve also should be regarded as protection scope of the present invention.
