Embodiment 1
[0031] please see figure 1 and figure 2, a rodent-proof and termite-proof cable, which includes a plurality of cable units 1, an inner sheath 2 covering a plurality of cable units, and an outer sheath 4 outside the inner sheath, characterized in that the inner sheath and There is also a rodent-proof and termite-proof layer 3 between the outer sheaths, and the rodent-proof and termite-proof layer 3 is composed of a sealed bag-like body 31 and a rat-proof and termite-proof part 33 located in the bag-like body; there are multiple bag-like bodies, Adjacent bags are separated by partitions 32; the thickness of the rodent and termite-proof layer is 0.20 mm to 0.80 mm; the rodent and termite-proof components are calcium carbonate, which exists in the bag-like bodies in the form of powder , the upper surface 311, the left surface 312, the lower surface 313, the right surface 314, and the front and rear surfaces of the bag-shaped body are gas and liquid-tight; the bag-shaped body is ...
Embodiment 2
[0034] please see image 3 , and refer to figure 2 , a rodent-proof and termite-proof cable, basically the same as the implementation example 1, the difference is that: the cable unit 1 is composed of an optical fiber 11 inside and a sleeve 12 outside the fiber; the cable unit is twisted around the central strength member .
[0035] Of course, among the five cable units in the figure, some of them may be filled ropes, and the filled ropes are solid or hollow structures made of polyethylene or polypropylene.
Embodiment 3
[0037] please see Figure 4 , and refer to figure 2 , a rodent-proof and termite-proof cable, basically the same as Example 2, the difference is: there is a cushion layer 5 between the rodent-proof and termite-proof layer and the inner sheath; the bag-shaped body is spirally coated or longitudinally Wrapped outside the inner sheath, there is a partial overlap between the rear helix and the front helix when the helix is wrapped, and there is an overlapping overlap when the longitudinal wrap is used; the material of the cushion layer is nylon 6 or nylon 12 or nylon 66 .
[0038] Of course, the rodent-proof and termite-proof cable described in any of the above implementation examples includes a plurality of cable units 1, an inner sheath 2 covering the plurality of cable units, and an outer sheath outside the inner sheath 4. It is characterized in that there is a rodent-proof and termite-proof layer 3 between the inner protective layer and the outer protective layer. The rod...
