The influence of trouble, rodent-proof characteristic are very prominent.
Description of the drawings
Fig. 1 is the schematic cross-section of cable in embodiment one.
Reference sign:1, crust；2, the first protective layer；3, armoured layer；4, the second protective layer；5, inner armor layer；
6, insulating layer；7, cable core；8, filler material.
Specific implementation mode
Embodiment one：
A kind of underground cable.
Referring to Fig.1, the cable ecto-entad be followed successively by crust 1, the first protective layer 2, armoured layer 3, the second protective layer 4,
Inner armor layer 5, insulating layer 6 and cable core 7 are filler material 8 between cable core 7.
In the present embodiment, crust 1 is using common cable sheath 1；First protective layer 2 and the second protective layer 4 are
Glass layer.Armoured layer 3 is the armor being entwined using stainless steel band；Inner armor layer 5 is using braided steel wire
Net cover；Insulating layer 6 and filler material 8 are all made of conventional cable materials.
The cable laying, after being buried in underground, when have mouse bite cable when, the crust 1 of cable was broken by the teeth before this, crust
After 1 is broken by the teeth, the first protective layer 2 is exposed, when mouse bites the first protective layer 2, since the first protective layer 2 is glass fibers
Layer is tieed up, when it is broken by the teeth, glass fibre is exposed, and since glass fibre is superfine and crisp, during mouse bites, is in
The cavity for injuring mouse is made to generate cable by the glass dregs of comminution fears sense, to achieve the effect that protection against rodents.
After cable long-time use, if the first protective layer 2 is gnawed rotten, armoured layer 3 will be exposed.Due to outer armour
Layer 3 is filled using stainless steel band, intensity and hardness are all very high, and mouse is difficult to be gnawed through.Armoured layer 3 can be in nylon
Cloth set gnawed it is rotten after highly desirable protect cable.
