Abstract
The invention provides a novel ant-proof and rat-proof cable comprising a cable core and an oversheath layer. The cable core is formed by the intertwist of at least one insulation wire core. Each insulation core comprises conductors and polyvinyl chloride insulation layers cladding the conductors. A water proof layer fills a gap among the insulation wire cores. A water-resistant taped cladding layer is arranged outside the water proof layer. An inner sheath is arranged outside the water-resistant taped cladding layer. A steel band armor layer is arranged between the inner sheath and the oversheath. Damages by rats and ants to the cable can be prevented, and a certain waterproof function can be realized, so that the usage life of the cable is substantially raised.
Description
Technical field
The present invention relates to a kind of power cable, relate in particular to a kind of Novel anti-mouse ant cable.
Background technology
Along with the develop rapidly of China's modernization construction, undergroundization of cable become inexorable trend.Adopt buried power cable to replace aerial line to have many advantages, as transmit electricity stable, safe and reliable, save metal and timber etc.Termite-resistant rodent-resistant cable, as special property cable, is generally used for the municipal works such as city water supply and sewage, sewage, road, bridge, tunnel, subway, square and tourist attractions, environmental facility.But how moist underground environment is, water has certain permeability to insulating material, affects the working life of cable.In recent years, the procreation speed of mouse, ant is surprising, extremely serious to the destruction of electric wire.
Summary of the invention
Technical problem to be solved by this invention is to overcome defect of the prior art, and a kind of Novel anti-mouse ant cable is provided, and not only can prevent the destruction of mouse ant to cable, also has certain water-proof function, has greatly improved the useful life of cable.
For solving the problems of the technologies described above, the invention provides a kind of Novel anti-mouse ant cable, comprise cable core and external sheath layer, cable core is by least one insulated wire cores twisted synthesizing cable, insulated wire cores comprises conductor and be wrapped in the polyvinyl chloride insulation layer outside conductor, the gap-fill watertight composition between insulated wire cores, the watertight composition peripheral hardware lapping layer that blocks water, the lapping layer peripheral hardware inner sheath that blocks water, is provided with steel-tape armouring layer between inner sheath and oversheath.
As a further improvement on the present invention, inner sheath and oversheath all adopt rat-and-ant proof halogen-free and low-smoke flame-retardant polyolefin.
As a further improvement on the present invention, watertight composition adopts radially waterproof material.
As a further improvement on the present invention, the lapping layer that blocks water adopts longitudinal water-blocking material.
The beneficial effect that the present invention reaches: the invention provides a kind of Novel anti-mouse ant cable, not only can prevent the destruction of mouse ant to cable, also there is certain water-proof function, greatly improved the useful life of cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of Novel anti-mouse ant cable.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, the invention provides a kind of Novel anti-mouse ant cable, comprise cable core and external sheath layer 7, cable core is by least one insulated wire cores twisted synthesizing cable, insulated wire cores comprises conductor 1 and is wrapped in the polyvinyl chloride insulation layer 2 outside conductor 1, the gap-fill watertight composition 3 between insulated wire cores, the watertight composition 3 peripheral hardwares lapping layer 4 that blocks water, the lapping layer 4 peripheral hardware inner sheaths 5 that block water, are provided with steel-tape armouring layer 6 between inner sheath 5 and oversheath 7; Inner sheath 5 and oversheath 7 all adopt rat-and-ant proof halogen-free and low-smoke flame-retardant polyolefin; Armour 6, inner sheath 5 and 7 pairs of cables of oversheath play the effect of double protection, prevent the destruction of mouse ant to cable; Watertight composition 3 and the lapping layer 4 that blocks water adopt respectively radially waterproof material and longitudinal water-blocking material, have solved the non-moistureproof problem of cable.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
