Abstract
Disclosed is a medium voltage termite-resistant cable with high performance. The medium voltage termite-resistant cable comprises: three circular conductor-twisting units, with the conductor units composed of a plurality of lead filaments, a conductor shielding layer wrapping the surface of the conductor units, an insulating layer wrapping the surface of the conductor shielding layer, an insulating shielding layer wrapping the surface of the insulating layer, a semiconduction belt layer wrapping the surface of the insulating shielding layer, a copper wire shielding layer coating the surface of the semiconduction belt layer, a filling layer coating the surface of the copper wire shielding layer, a cladding layer coating the surface of the filling layer, a nylon layer coating the surface of the cladding layer, and an oversheath covering the surface of the nylon layer. The medium voltage termite-resistant cable of the utility model features high mechanical strength, high hardness, excellent wear-resisting and cutting-resisting capability, and great lubricity, thereby being equipped with the merits of water proof, termite proof, and robust mechanical strength.
Description
Technical field
The utility model relates to a kind of power cable, relates in particular to and presses termite-proof cable in a kind of high-performance.
Background technology
At present, the common crosslinked polyetylene insulated steel wire happy dress pvc sheath power cable of general employing in the existing electric power system, this series products waterproof ability is poor, and steel wire is perishable, can not bear due short-time overload electric current; And the pvc sheath corrosion resistance is poor, is prone to destroyed by insects such as termites.If sheath suffers insect bite, the cable electrical degradation, shorten useful life.In case and breaking out of fire, this of burning type cable can discharge the toxic gas and the dense smoke of a large amount of Halogens, has not only influenced normally carrying out of disaster relief work, and the safety of the direct threats person.Therefore, the intensity that how to design a mechanism height, the medium-pressure power cable that hardness is big, wear-resisting, the cutting resistance ability is excellent, lubrification is strong become the direction that those of ordinary skills make great efforts.
Summary of the invention
The utility model provides and presses termite-proof cable in a kind of high-performance; The advantage that the mechanical strength that this termite-proof cable has is high, hardness is big, wear-resisting, the cutting resistance ability is excellent, lubrification is strong, thus make cable have good waterproof, termite-proof and high characteristics such as mechanical strength.
For achieving the above object, the technical scheme that the utility model adopts is: press termite-proof cable in a kind of high-performance, comprising:
Three circular stranded conductor unit, this conductor element is made up of some wire;
One conductor shield is coated on said conductor element surface;
One insulating barrier is coated on said conductor screen laminar surface;
One insulation screen is coated on said surface of insulating layer;
One semi-conductive tape layer is coated on said insulation shielding laminar surface;
One copper wire screen is coated on said semi-conductive tape laminar surface;
One packed layer is coated on said copper wire screen surface;
One lapping layer is wrapped in said packed layer surface;
One nylon layer is coated on said lapping layer surface;
One oversheath is coated on said nylon layer surface.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said packed layer is made up of some glass fiber.
2, in the such scheme, an inner covering is between said lapping layer and nylon layer.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
Press termite-proof cable in the utility model high-performance; The advantage that mechanical strength is high, hardness is big, wear-resisting, the cutting resistance ability is excellent, lubrification is strong of utilizing nylon self to have; Extrude outside cable conductor (or insulated wire cores); As the sheath (inner sheath) of cable, thereby make cable have good waterproof, termite-proof and high characteristics such as mechanical strength.Secondly, the development of this termite-proof cable both can solve the serious problem of China's south sough termite damage cable, also can satisfy the requirement of overseas market (like Australia), had broad application prospects.
Description of drawings
Accompanying drawing 1 is to press termite-proof construction of cable sketch map in the utility model high-performance.
In the above accompanying drawing: 1, conductor element; 2, wire; 3, conductor shield; 4, insulating barrier; 5, insulation screen; 6, semiconductive belt; 7, copper wire screen; 8, packed layer; 9, lapping layer; 10, nylon layer; 11, oversheath; 12, inner covering.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: press termite-proof cable in a kind of high-performance, it is characterized in that: comprising:
Three circular stranded conductor unit 1, this conductor element 1 is made up of some wire 2;
