Description
Technical field
The present invention relates to a kind of cable, and in particular to a kind of anti-termite cable.
Background technology
Domestic current anti-termite cable mainly uses chemical prevention method, for example repellant is added in cable jacket, or ant proof medicine is quantitatively regularly added in cable duct, a malicious ring of encirclement is formed around cable, termite is contacted cable, or touch pesticide-clay mixture and be poisoned to death.Ecological Disposal method is also used sometimes in addition, as laid under water level, avoids termite living environment.In both the above method, former can cause environmental pollution, and latter can increase laying difficulty, and improve laid down cost.
The content of the invention
Goal of the invention：The invention aims to overcome deficiency of the prior art, there is provided a kind of termite-proof effect is good, comprehensive moistureproof, the high anti-termite cable of bulk strength.
Technical scheme：In order to solve the above-mentioned technical problem,A kind of anti-termite cable of the present invention,It includes power wire core conductor,Insulating barrier is provided with outside the power wire core conductor,They form conductive unit,The conductive unit sets four altogether,Their tangent settings,Packed layer is provided with outside the conductive unit,It is wrapped outside the packed layer to be provided with waterstop,Vertical bag is provided with outside the waterstop and is provided with aluminium-plastic tape,Medium density polyethylene inner sheath is provided with outside the aluminium-plastic tape,Aluminium-plastic tape and the medium density polyethylene inner sheath is extruded and formed simultaneously,It is wrapped outside the medium density polyethylene inner sheath to be provided with armouring tape,High-density polyethylene layer is provided with outside the armouring tape,Polyolefin termite-proof layer is provided with outside the high-density polyethylene layer,The high-density polyethylene layer and polyolefin termite-proof layer composition oversheath,The high-density polyethylene layer and polyolefin termite-proof layer are co-extruded.
For the power wire core conductor to press rigid structure conductor, tightening factor reaches 0.92.
The insulating barrier is RPVC layer or medium density polyethylene layer.
The packed layer is waterproofing rope.
The PE plastic layers of the aluminium-plastic tape are outside.
The wrapped double armor steel band outside the medium density polyethylene inner sheath.
The insulating barrier uses RPVC or medium density polyethylene, after insulated wire cores stranding, is filled using waterproofing rope, using comprehensive damp-proof layer outside cable core, is provided with aluminium-plastic tape in comprehensive damp-proof layer, while can stop the intrusion of termite.
The restrictive coating of cable is used using high density polyethylene (HDPE) protective cover material and high rigidity special type polyolefin termite-proof sheath.Polyolefin termite-proof sheath hardness is more than shore 65, can be simple with pe sheath double-layer coextrusion, technique to environment friendly and pollution-free.
The structure design of cable, there is the termite-proof setting of multilayer, the erosion of termite can be resisted completely, while also in relation with the habit of termite, there is provided water-blocking moistureproof layer, ensures that cable also can be used normally in wet environment.
For power wire core conductor using pressing rigid structure conductor, tightening factor reaches 0.92, substantially very close to each other between conductor, can effectively prevent the entrance of moisture.
The insulating barrier uses RPVC or medium density polyethylene, both ensures dielectric strength, while has with enough hardness, can be stung with termite-proof invade.
Filled between cable core using waterproofing rope, wrapped using waterstop after stranding, waterproofing rope and waterstop can absorb the moisture content in environment, prevent moisture content from entering insulating barrier, influence insulation function.
One layer of aluminium-plastic tape of vertical bag outside waterstop, PE plastic layers are outside, and extrude medium density polyethylene inner sheath simultaneously, together with aluminium-plastic tape is fully bonded to medium density polyethylene inner sheath, play waterproof and dampproof termite-proof function.
The armoured clad steel band of medium density polyethylene inner sheath, strengthen the tension resistance ability of cable, to protect cable to be directly laid in underground.
The outer double-layer coextrusion extrusion high density polyethylene (HDPE) of steel band and extraordinary polyolefin termite-proof sheath, high density polyethylene (HDPE) has very high intensity and hardness, and extraordinary polyolefin termite-proof sheath hardness is more than shore 65, this combining structure, with the extraordinary termite-proof function of biting, and it is environment friendly and pollution-free.
Beneficial effect：Compared with prior art, its remarkable advantage is the present invention：The present invention is on the construction of cable using high-density polyethylene layer and high rigidity special type polyolefin termite-proof sheath, even if termite is close, also can not bite in sheath, cable can not be corroded, comprehensive damp-proof layer is used in the construction of cable simultaneously, contains aluminium foil in comprehensive damp-proof layer, termite-proof can also enter, waterproofing rope and waterstop can absorb the moisture content in environment, prevent moisture content from entering insulating barrier.
