Abstract
The utility model relates to the improvement of a termite-proof cable, which is characterized in that a termite protecting layer is at least composed of an inner protecting layer of high-density polyethylene, a middle nylon protecting layer and an outer protecting layer of high-density polyethylene. Anti-termite damaging ability is evidently enhanced by three layers of protecting layers of high-hardness composite materials, termite biting and eating protection is enhanced, and favorable termite-protecting effects can be obtained by the utility model under the condition of environmental protection and no medicine contamination. The brittle nylon protecting layer is effectively protected by the inner and the outer double layers of protecting layers of high-density polyethylene which are favorable for moulding of a nylon protecting layer. The proposal of the utility model both can be used for a power cable and can also be used for other cables such as a communication cable, etc.
Description
Technical field
Utility model is about the improvement to termite-proof cable, relates in particular to the termite-proof cable of a kind of avirulence environment-friendly type.
Background technology
Cable is termite-proof, is to add the medicine type anti-termite agent in cable sheath material than common method, and this type of technology is by multinomial patent report.Add the medicine type anti-termite agent in the protective cover material, though can reach certain termite-proof effect.Yet usually the medicine type anti-termite agent all is poisonous, can cause the pollution of noxious substance, along with the environmental requirement that improves day by day, and the use that tends to be under an embargo of this cable.In addition, add the medicine type anti-termite agent in the sheath material, also can damage the performance of sheath material, improved so need add some other auxiliary agent sometimes, this can cause the increase of cost again.
Chinese patent CN96111838.5 disclosed termite-proof in pressure, low pressure and signal cable, then adopt to comprise density and be at least 0.9g/cm3 outer layer of polyethene armouring.Though the polyethylene of density more than 0.9g/cm3, its hardness is higher, can play termite-proof stinging and eat effect, and it is actual because material hardness is enough big inadequately, therefore anti-ly stings that to eat effect still limited, still has worth improved place.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of termite-proof performance better, the termite-proof cable of longer service life.
The utility model purpose realizes that main the improvement is with termite-proof polyethylene armour, changes high density polyethylene (HDPE) internal layer, nylon sheath wire intermediate layer, the outer compound termite-proof layer of high density polyethylene (HDPE) into, thereby has improved termite-proof effect.Specifically, the termite-proof cable of utility model comprises conductor and outer termite overcoat, it is characterized in that said termite overcoat has at least high density polyethylene (HDPE) sheath, middle nylon sheath and high density polyethylene (HDPE) outer jacket to form.
Utility model can also increase a metal, especially nonmagnetic material armour again outside the nylon sheath, with the anti-ant effect of further raising.
In addition, as required can also conductor and outside between the termite overcoat, increase other functional layers, as conductor shield, insulation screen, metal screen layer etc.
The termite-proof cable of utility model, owing to adopt high density polyethylene (HDPE) internal layer, nylon sheath wire intermediate layer, the termite-proof layer of the outer compound physical of high density polyethylene (HDPE), because of nylon has higher intensity than high density polyethylene (HDPE), three floor height hard composite overcoats have significantly strengthened termite-proof infringement ability, improved termite-proof stinging greatly and eaten, and can make cable under the situation of environmental protection medicine-less pollution, obtain good termite-proof effect.Inside and outside double-deck high density polyethylene (HDPE) overcoat has not only effectively been protected the nylon overcoat of fragility, and has been helped the processing and forming of nylon sheath.The utility model scheme both can be used for power cable, also can be used for other as telecommunication cable etc.
Below in conjunction with two embodiments, further specify utility model.
Description of drawings
Fig. 1 is the utility model first embodiment power cable structural representation.
Fig. 2 is the utility model second embodiment power cable structural representation.
Fig. 3 is utility model the 3rd an embodiment power cable structural representation.
Embodiment
Embodiment 1: referring to Fig. 1, the termite-proof single-core power cables of utility model is made up of conductor 1, insulation 2, high density polyethylene (HDPE) sheath 3, nylon layer 4, high density polyethylene (HDPE) 5 from inside to outside successively.
Embodiment 2: referring to Fig. 2, as embodiment 1, increasing outside conductor 1 has conductor shield 6, and insulation screen 7 and metal screen layer 8 are arranged respectively outside the insulating barrier 2.
Embodiment 3: referring to Fig. 3, and termite-proof three core power cables of utility model, each core is made up of conductor 1, conductor shield 6, insulating barrier 2, insulation screen 7 and metal screen layer 8.Three cores are delta arrangement, and fill the space strandings by filling 10, are tightened by lapping layer 11 outward, and extruding high density polyethylene (HDPE) sheath 3, nylon layer 4, nylon sheath wire respectively has the wrapped armour 9 of nonmagnetic metal band outward, and outermost layer is a high density polyethylene (HDPE) 5.
Above-mentioned termite-proof structure can also be used for other non-electricity cables.
Claims (3)
1, termite-proof cable comprises conductor and outer termite overcoat, it is characterized in that said termite overcoat has at least high density polyethylene (HDPE) sheath, middle nylon sheath and high density polyethylene (HDPE) outer jacket to form.
2,, it is characterized in that the nylon sheath has the metal armouring layer outward according to the described termite-proof cable of claim 1.
