Abstract
The utility model provides an oil resistant environment-friendly photovoltaic cable with high light transmittance, which comprises a plurality of conductors, an insulating layer used for coating the conductors and a sheath, wherein the plurality of conductors, which are coated by the insulating layer, are mutually stranded to form a cable core, the outer side of the cable core is coated by the sheath, and the sheath is an irradiation crosslinked low-smoke oil resistant polyolefin sheath. Compared with the prior art, the sheath of the oil resistant environment-friendly photovoltaic cable is made by adopting irradiation crosslinked low-smoke oil resistant polyolefin, thereby enabling the photovoltaic cable provided by the utility model to has the advantages of small amount of combustion smoke, high light transmittance and good oil resistance. In addition, the irradiation crosslinked polyolefin is adopted, electron accelerator irradiation is adopted, a traditional vulcanization crosslinked process is replaced, investment of production equipment is less, the production efficiency is higher, and the production cost of the photovoltaic cable is greatly reduced.
Description
Technical field
The utility model relates to a kind of photovoltaic cable, especially a kind of high transmission rate oil resistant environmental protection photovoltaic cable.
Background technology
Recently, China's air quality degradation, haze takes place frequently, and low visibility brings great puzzlement to people's life.A main cause that causes haze is the smoke particle that burning object produces, and during cable fire, also can produce a large amount of smog, so people also further improve the environmental requirement of cable.In photovoltaic cable when exploitation,, the aspect mainly paid close attention to concentrated on the performances such as fire-retardant, heatproof, useful life, and whether do not consider needs to possess low cigarette, and while therefore burning, the amount of being fuming is very large, does not meet nowadays environmental protection development trend.
In solar power generation process in order to improve generating efficiency, solar panel need to be kept at an angle with shining upon light, therefore need a kind of mechanical device, according to the track of sun operation, solar panel is carried out to the adjustment of angle at any time, in the process of adjusting, photovoltaic cable can touch the lubricating oil in mechanical device unavoidably.Therefore photovoltaic cable need possess oil resistance, to extend its useful life.And common photovoltaic cable does not possess the characteristic of oil resistant, useful life is short, breaks down many.Therefore, need to develop a kind of photovoltaic cable with oil resistance.And oil resistant photovoltaic cable of the prior art is all to adopt vulcanized rubber to manufacture, and the vulcanization crosslinking equipment of manufacture vulcanized rubber is quite complicated, and not only cost is high but also efficiency is low, and in manufacture process, can produce poison gas, the not environmental protection of penetrating odor.
Summary of the invention
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of high transmission rate oil resistant environmental protection photovoltaic cable, and this kind of photovoltaic cable manufacturing cost is lower, production process environmental protection and possess low cigarette, high transmission rate and oil resistance more.
For achieving the above object, the utility model provides a kind of high transmission rate oil resistant environmental protection photovoltaic cable, the insulating barrier and the sheath that comprise some conductors, coated described conductor, be coated with the mutual stranded formation cable core of described some conductors of insulating barrier, the outside of described cable core is coated with described sheath, it is characterized in that: described sheath is the low cigarette oil-resisting type of cross-linking radiation polyolefin jacket.
Preferably, described insulating barrier is the low cigarette type of cross-linking radiation polyolefin insulation layer.
More preferably, described conductor is by mutual stranded the forming of some wires.
Further, described wire is copper wire.
Further, the quantity of described conductor is three.
Compared to prior art, the beneficial effects of the utility model are: because described sheath of the present utility model is to adopt the low cigarette oil-resisting type of cross-linking radiation polyolefin to make, thereby make that photovoltaic cable of the present utility model has advantages of that burning fuming amount is little, smoke density is low, high transmission rate, oil resistance be good, and employing cross-linking radiation polyolefin, adopt electron accelerator irradiation, replaced traditional vulcanization crosslinking technique, production equipment less investment, production efficiency is higher, greatly reduces the production cost of photovoltaic cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model high transmission rate oil resistant environmental protection photovoltaic cable.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Refer to shown in Fig. 1, the utility model high transmission rate oil resistant environmental protection photovoltaic cable 100, for photovoltaic equipment, comprises some conductors 10, insulating barrier 20 and sheath 30, and the outside of every conductor 10 is coated with described insulating barrier 20.Described conductor 10 is to form by some wires 11 are stranded, thereby the pliability of described conductor 10 can be provided.In the present embodiment, described conductor is three, and described wire 11 is copper wire, but the quantity of described conductor 10 is unrestricted, and the quantity of conductor 10 can be set as the case may be flexibly.The mutual stranded formation cable core of conductor 10 that is coated with described insulating barrier 20, the outside of described cable core is coated with described sheath 30.Described insulating barrier 20 adopts the low cigarette type of cross-linking radiation polyolefin to make, and described sheath 30 adopts the low cigarette oil-resisting type of cross-linking radiation polyolefin to make, and the low cigarette oil-resisting type of described cross-linking radiation polyolefin has the advantages such as good insulating, oil resistant, low cigarette, high flame retardant.Owing to adopting this structure, when photovoltaic cable 100 of the present utility model has advantages of burning, low, the high transmission rate of smoke density and oil resistance are good.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection range of the present utility model.
