Abstract
The utility model discloses an environment -friendly termite resistance power cable, including many conductors, around external shielding layer the insulating layer outside of the outer insulating layer of the semiconduction area, cladding of package many conductors outside shielding layer including the internal shield layer of semiconduction outband, cladding, cladding, is blocking water the aluminium of outband and is overlapping and the oversheath of cladding outside aluminium overlaps around wrapping the area that blocks water, cladding outside the external shielding layer. The aluminium cover is in through extruding the crowded package of seamless pharcidous mode in succession the surface that blocks water and take, still be equipped with the pitch layer between aluminium cover and the oversheath, the oversheath adopts medium density polyethylene material producing, still crowd the nylon that a package layer thickness is 0.5mm on the surface of oversheath. The utility model discloses an environment -friendly termite resistance power cable has good preventing and stings and bite the performance, can effectively prevent the infringement of termite, and is pollution -free moreover, does not influence the cable bending and lays construction convenience.
Description
Technical field
The utility model relates to a kind of environment-friendly type Anti-termite power cable.
Background technology
Power cable with cross-linked polyethylene insulation is owing to having good electric property, and the series of advantages such as laying installation is relatively simple, and operation maintenance is convenient, are thus widely used.Along with the increase of usage quantity, cable jacket is also seemed by the problem of biological damage to become increasingly conspicuous, and particularly the anti-ant problem of southern area cable, needs the great attention causing us.Termite can not only gnaw through cable sheath, can also break through metal carbonyl coat, and cable insulation is made moist, and insulation resistance declines, thus causes single-line to ground fault, even sets off an explosion, makes cable line generation permanent fault.Only In Guangdong Province accounts for the 60%-70% of cable fault sum due to fault that the harm of termite to cable causes according to statistics.Therefore a kind of cable that can effectively prevent from termite to sting biting urgently is developed.
Utility model content
The purpose of this utility model is to overcome the defect of prior art and provides a kind of environment-friendly type Anti-termite power cable, and it has good anti-bitely bites performance, effectively can prevent the infringement of termite, and pollution-free, and not affecting cable bend lays, easy construction.
The purpose of this utility model is achieved in that a kind of environment-friendly type Anti-termite power cable, comprise many conductors, wrapped semi-conductive tape outside many conductors, the internal shield be coated on outside semi-conductive tape, the insulating barrier be coated on outside internal shield, the outer shielding layer be coated on outside insulating barrier, wrapped waterstop outside outer shielding layer, the oversheath that is coated on the aluminium cover outside waterstop and is coated on outside aluminium cover, wherein
Described aluminium cover is extruded in the outer surface of described waterstop by the mode extruding seamless wrinkle continuously;
Also bitumen layer is provided with between described aluminium cover and oversheath;
Described oversheath adopts medium density polyethylene material to make;
The outer surface of described oversheath also extrudes the nylon that a layer thickness is 0.5mm.
Above-mentioned environment-friendly type Anti-termite power cable, wherein, described many conductors are divided into five sector elements.
Above-mentioned environment-friendly type Anti-termite power cable, wherein, described waterstop is semi-conductive buffer water-blocking band.
Environment-friendly type Anti-termite power cable of the present utility model, employing physics mode is termite-proof, namely the higher nylon of one deck hardness is also extruded at the outer surface of cable jacket, this nylon belongs to ep-type material, have and good anti-bitely bite performance, effectively can prevent the infringement of termite, and it is pollution-free, the technique of available routine is extruded again, and the cable smooth in appearance that the surface of cable is extruded, be combined closely with oversheath, ensure that mechanical and physical performance and the electrical property of cable, do not affect cable bend to lay, easy construction.
Accompanying drawing explanation
Fig. 1 is the sectional view of environment-friendly type Anti-termite power cable of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
First refer to Fig. 1, a kind of environment-friendly type Anti-termite power cable of the present utility model, comprise many conductors 1, wrapped semi-conductive tape 2 outside many conductors 1, the internal shield 3 be coated on outside semi-conductive tape 2, the insulating barrier 4 be coated on outside internal shield 3, the outer shielding layer 5 be coated on outside insulating barrier 4, wrapped waterstop 6 outside outer shielding layer 5, the oversheath 9 that is coated on the aluminium cover 7 outside waterstop 6 and is coated on outside aluminium cover 7, wherein:
Many conductors 1 are divided into five sector elements;
Waterstop 6 is semi-conductive buffer water-blocking band;
Aluminium cover 7 is extruded in the outer surface of waterstop 6 by the mode extruding seamless wrinkle continuously;
Bitumen layer 8 is also provided with between aluminium cover 7 and oversheath 9; Bitumen layer 8 has waterproof, protection against the tide and corrosion-resistant effect;
Oversheath 9 adopts medium density polyethylene material to make;
The outer surface of oversheath 9 also extrudes the nylon 10 that a layer thickness is 0.5mm; Nylon PA1012 selected by nylon 10, and the hardness of this nylon layer 10, up to shore (D) more than 65, makes termite sting motionless cable, and pollution-free, and the technique of available routine is extruded again.
Environment-friendly type Anti-termite power cable of the present utility model, employing physics mode is termite-proof, namely also extrude at the outer surface of cable jacket the nylon that a layer thickness is 0.5mm, the hardness of this nylon layer is up to shore (D) more than 65, have and good anti-bitely bite performance, effectively can prevent the infringement of termite, and it is pollution-free, the technique of available routine is extruded again, and the cable smooth in appearance that the surface of cable is extruded, be combined closely with oversheath, ensure that mechanical and physical performance and the electrical property of cable, do not affect cable bend to lay, easy construction.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit and scope of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
