It is not limited to the patent that front enumerates and does not provide the technical issues of being addressed the puzzlement industry that applicant is mentioned above
Enlightenment, technical solution described below generate in this background.
Summary of the invention
Task of the invention lies in provide one kind and help avoid insulated wire cores in the case where encountering TRANSIENT HIGH TEMPERATURE and external force to occur
Damage in insulation and even if the distributed photovoltaic power generation cable that insulated wire cores can still work as usual when oversheath occurs damaged.
The task of the present invention is come what is completed, a kind of distributed photovoltaic power generation cable is included in length direction holding in this way
A pair of of the insulated wire cores and extrusion sticked together parallel and mutually with tangential manner outside a pair of of insulated wire cores one outside protect
Set, respectively by conductor and successively insulating layer and inner sheath of the extrusion outside conductor are constituted a pair of of insulated wire cores, are characterized in that institute
The insulating layer stated is the semi-rigid polyvinyl chloride that nylon film layer is combined on outer wall.
In a specific embodiment of the invention, the conductor is bare copper wire or silver-gilt copper wire.
In another specific embodiment of the invention, the inner sheath is nylon.
In another specific embodiment of the invention, the oversheath is polyvinyl chloride.
Technical solution provided by the invention is due in a creative way using the insulating layer of the structural system of a pair of of insulated wire cores
The semi-rigid polyvinyl chloride of nylon film layer is combined on outer wall, thus emerges from excellent high temperature resistant and impact resistance,
Avoid insulated wire cores to occur insulating layer under encountering TRANSIENT HIGH TEMPERATURE and external impacts damaged and even if when oversheath occurs damaged,
Insulated wire cores can still shine work.
Detailed description of the invention
Fig. 1 is the embodiment of the present invention schematic diagram.
Specific embodiment
Referring to Figure 1, it shows and keeps a pair that is parallel and mutually sticking together with tangential manner in length direction
The oversheath 2 of insulated wire cores 1 and extrusion outside a pair of of insulated wire cores 1, a pair of of insulated wire cores 1 are respectively squeezed by conductor 11 and successively
The insulating layer 12 and inner sheath 13 overlayed on outside conductor 11 is constituted.
Technical essential as technical solution provided by the invention: insulating layer 12 above-mentioned is to be combined with nylon membrane on outer wall
The semi-rigid polyvinyl chloride of layer, i.e. insulating layer 12 are SR-PVC+ thin-walled nylon structure.
SR-PVC, that is, semi-rigid above-mentioned polyvinyl chloride has following strong point: since the degree of polymerization is significantly higher than PVC, thus machine
Tool is had excellent performance；Since hardness is high and up to 90A, and the hardness of common PVC is 75-85A, thus is emerged from excellent resistance to
Grind performance；Since SR-PVC is in burning, flame leaves just to be extinguished at once, and common PVC need to be after the 3-4S after flame leaves
Extinguish, thus there is ideal anti-flammability.Nylon has resistance to combustion, tensile strength high (up to 104 kPas), wear-resisting and electrical insulating property good
The characteristics of, therefore aforementioned dielectric layer 12 of the invention can be made to embody ultimate attainment effect, i.e., embodiment applicant is in technology above
The technical effect recorded in effect column.
In the present embodiment, conductor 11 above-mentioned is bare copper wire but it is also possible to be silver-gilt copper wire；Inner sheath 13 above-mentioned is
Nylon；Oversheath 2 above-mentioned is polyvinyl chloride.
Preferably, in manufacturing process of the invention, the extrusion of aforementioned oversheath 2 uses interior wall mould, and inner wall uses mirror
Face polishing forms the step of corrugated on the surface of oversheath 2 due to mould inner wall is rough to eliminate.In addition, if mold
Inner wall lose it is smooth, then oversheath can be undermined.
Preferably, in manufacturing process of the invention, external mold uses the mold with certain radian, this is because material has
Shrinkage, it is oval in cross-sectional shape of the invention then if using straight mold according to conventional thinking
Two plane positions will appear recess.It is through non-finite number of time made by the applicant experiments have shown that: using with cambered mould
The flat horizontal surface of the distributed photovoltaic power generation cable of the present invention of tool manufacture is smooth substantial and without recess, and is squeezing out oversheath 2
In the process, scratch will not be caused to the inner sheath 13 that material is nylon, is further ensured that insulation core wire 1 is able under harsh environment
It works normally without generating the risk because failing caused by insulation.
In conclusion technical solution provided by the invention compensates for the shortcoming in prior art, invention has been favorably accomplished
Task has faithfully fulfilled the technical effect that applicant refers in technical effect column above.
