Abstract
The invention provides a photovoltaic cable production technology which comprises the steps that a plurality of tinned copper wires are bunch-twisted to form a conductor in a layering way along the same direction for many times; an insulation layer is extruded and wrapped on the surface of the conductor and is subjected to cooling processing; a protection layer is extruded and wrapped on the outer side of the insulation layer; the insulation layer is subjected to one-time extrusion molding; the one-time extrusion molding step, the cooling treatment step and the protection layer extrusion step are completed at the same production line. According to the photovoltaic cable production technology, the extrusion and the cooling of the insulation layer and the extrusion and the wrapping of the protection are sectionally and continuously carried out on the same production line, the problems that the surface of the insulation layer is polluted and damaged when the two-time extrusion is separately carried out and the like are avoided, two layers of an insulating sheath are tightly combined, the cable concentricity is ensured, and the production quality is improved.
Description
Technical field
The present invention relates to cable production technical field, particularly a kind of production technology of photovoltaic cable.
Background technology
Solar photovoltaic technology is as one of following green energy resource technology, and its development and popularization will be day by day extensive all over the world.The performance of photovoltaic generating system not only depends on efficiency or the performance of solar components self, also needs many seeming and the parts of assembly without direct relation, such as terminal box, inverter and photovoltaic cable.Wherein, photovoltaic cable is also one of key factor having influence on the useful life of whole photovoltaic generating system.Because solar energy photovoltaic system usually can use under severe environmental conditions, such as the environment of high temperature and high ultraviolet radiation.Therefore, the photovoltaic cable that photovoltaic generating system uses also has strict requirement, except selecting of high temperature resistant, anti-ultraviolet material, also to there is the ability of very strong anti-mechanical load, so during installation and maintenance, cable can connect up on the sharp edge of roof structure, pressure, bending, tension force be can bear simultaneously, load and powerful impact are stretched across, if cable cover(ing) insufficient strength, cable insulation will be subject to badly damaged, thereby affect the useful life of whole cable, or cause short circuit, fire and personnel to injure the appearance of the problems such as danger.In traditional cable production technology; it is to be divided into two production lines to produce respectively that insulating exruded operation and outer protection layer are extruded operation; complete after insulating exruded operation at a production line; cable winding becomes package; again package cable moving is carried out to sheathing operation to another production line by cable-uncoiling; production process extends, and quality is restive, cost of idleness when production.
Summary of the invention
The object of the present invention is to provide a kind of production technology of photovoltaic cable, it can improve the quality of cable product, the excellent insulation property of reduction production cost and assurance cable.
Concrete, to achieve the object of the present invention, the production technology of a kind of photovoltaic cable of the present invention comprises step: will be with many tinned copper wire layerings, repeatedly, bundle is stranding into conductor in the same way; At conductive surface extruded insulation layer; Insulating barrier cooling processing; And extrude protective layer in insulation outside; Wherein said insulating barrier is that an extrusion molding and itself and cooling processing step and protective layer extrusion step complete at same machining production line.
Preferably, described insulating barrier is low smoke halogen-free flame-retardant polyolefin insulating barrier.
Preferred again, described protective layer is cross-linked polyolefin protective layer.
Adopt photovoltaic cable production technology of the present invention; the extruding of the extruding of insulating barrier, cooling and protective layer is coated on segmentation on same production line and carries out continuously; can avoid owing to extruding while separately carrying out that surface of insulating layer is polluted for twice and the problem such as damage occurs; make to combine closely between insulating sleeve two-layer; guarantee cable concentricity, improve the quality of products.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the present invention is aforesaid will be become apparent with other object, feature and advantage.Wherein:
Figure 1 shows that the cross-sectional view of photovoltaic cable;
Figure 2 shows that the flow chart of steps of the production technology of photovoltaic cable of the present invention.
Embodiment
The cross-sectional view of photovoltaic cable as shown in Figure 1, it comprises the conductor 10 of portion of cable center, the peripheral coated insulating barrier 20 of conductor 10 and at the peripheral coated protective layers 30 of insulating barrier 20.According to the applied environment of photovoltaic cable and special performance requirement, as shown in Figure 2, it comprises the processing step of production photovoltaic cable of the present invention:
S1: will be with many tinned copper wire layerings, repeatedly, bundle is stranding into conductor in the same way;
S2: at conductive surface extruded insulation layer;
S3: insulating barrier cooling processing; And
S4: extrude protective layer in insulation outside; Wherein said insulating barrier is that an extrusion molding and itself and cooling processing step and protective layer extrusion step complete at same machining production line.
Owing to adopting the cross-linked technique of radiation can change the chemical constitution of polymer, make meltability thermoplastic material be converted to non-meltability elastomeric material, it can significantly improve thermal characteristic, mechanical property and the chemical characteristic of cable insulation material.Therefore, one preferred embodiment in,, described insulating barrier is low smoke halogen-free flame-retardant polyolefin insulating barrier, described protective layer is cross-linked polyolefin protective layer, reaches preferably insulation effect and makes the protective layer of cable have very strong mechanical performance with this.
Photovoltaic cable production technology of the present invention adopts the continuous expressing technique of segmentation; the extruding of the extruding of insulating barrier, cooling and protective layer is coated on segmentation on same production line and carries out continuously; avoid twice point to open while extruding that surface of insulating layer is polluted and the problem such as damage occurs; make to combine closely between insulating sleeve two-layer; guarantee cable concentricity, improve the quality of products.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention openly in scope, still can do some corrections or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
