Description
Technical field
The present invention relates to a kind of manufacture crafts of distribution cable medial head, particularly suitable in the laid processes of distribution cable
It uses, belongs to distribution technique field.
Background technique
Currently, when encountering institute's laying-out length more than piece cable length, needing to make in distribution cable laid processes
Cable mid head connects two sections of cable runs, and often humidity is larger or even some places are arranged in the place of end laying
When water is unsmooth, partial cables are directly immersed in water, and the cable mid head leakproofness of traditional handicraft production is poor, easy to aging, are easy hair
Raw failure.According to statistics, end aging, failure have become one of the main reason for distribution fault has a power failure.
Since cable laying is in underground, once it breaks down, it is extremely difficult to search fault point.Especially to some laying time ratios
Relatively long, gap marker is unclear, even more so, but often exactly these cable runs because the cable mid head time longer more hold
It is easy to aging to break down.When cable mid head breaks down, difficulty is searched, repair time is long, and the power supply for seriously affecting distribution can
By property.
It would therefore be highly desirable to a kind of novel cable medial head manufacture craft that can overcome the above problem occur.

Both ends extend to reagency and bore on 9 inclined-planes；
10, insulating tape is wound in the outer surface of interior waterproof hot melt layer 11, restores insulating layer 7；
11, waterproof hot melt is wound in 7 outer surface of insulating layer, forms outer waterproof hot melt layer 12；
12, heat-shrink tube 13 is sealingly fastened in outside outer waterproof hot melt layer 12；
13, copper shield 3, installing ground line are set outside outer waterproof hot melt layer 12；
14, cable cover(ing) 1 is installed in the external of copper shield 3.
Preferably, in the step 1, it is respectively 60 centimetres, 80 centimetres that the cable cover(ing) 1 of two cables, which strips length,；
Preferably, in the step 3, it is 21 centimetres that the copper shield 3 of two cables, which strips length,；
Preferably, in the step 4, it is 18 centimetres that the outer semiconductor layer 5 of two cables, which strips length,；
Preferably, in the step 5, it is respectively 4.5 centimetres, 5 lis that insulating layer 7, the inner semiconductor layer 8 of two cables, which strip length,
Rice.
The main innovation point of novel cable medial head manufacture craft of the invention is two layers of waterproof hot melt process of increase,
So that waterproof seal greatly improves, the present invention can effectively reduce the matching for causing due to steam invasion causes decreasing insulating
Electric fault can make cable mid head be laid in the bigger place of humidity, and good airproof performance is anti-aging, and the dimension in later period is effectively reduced
Shield is taken, and is included
1, easy to operate, practical, general staff slightly trains and can grasp；
2, applied widely, it is applicable to the production of different model cable mid head, and the cable mid head made can be used for more
It works under high humility；
3, operating cost is reduced, compared with common process, the end non-failure operation time made of novel process is longer,
The later period is effectively reduced using operating cost.
In conclusion present invention process is simple and direct, easily operated, cable pack-off is strong, and insulation effect is good, durable, can have
Effect reduces Distribution Network Failure rate, reduces later maintenance cost, has a good application prospect.
