Description
Technical field
This utility model belongs to field of cable technology, especially relates to a kind of photovoltaic cable.
Background technology
Following heliotechnics is by one of green energy resource technology of becoming, and solar energy or photovoltaic application will be day by day extensive, and in addition to the photovoltaic generation factory of governmental support quickly grows, private investor the most actively founds the factory.But heliotechnics depends not only on efficiency or the high-performance of solar components self, also be unable to do without the service cable system supporting with it.And these systems do not have the performances such as good tensile strength, high temperature resistant, low temperature resistant, ozone-resistant, uvioresistant, resistance to steam, wear-resisting, shock resistance, high electric insulation and high fire-retardance, and keep in repair and safeguard solar energy system costly, the service life of whole system is shorter；Therefore improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, thering is provided a kind of photovoltaic cable, it has length in service life, good tensile strength, high temperature resistant, low temperature resistant, ozone-resistant, uvioresistant, resistance to steam, wear-resisting, shock resistance, high electric insulation and the performance characteristics of high fire-retardance.
In order to realize above-mentioned purpose, this utility model be the technical scheme is that a kind of photovoltaic cable, including conductor, the outer surface of described conductor is enclosed with insulating barrier, described insulating barrier includes inner insulating layer and external insulation layer, described inner insulating layer uses cross-linking radiation polyolefine material, and described external insulation layer uses irradiation cross-linking flame-retardant polyolefine material；Described external insulation layer is cladded with equipped with outer jacket, is provided with reinforcing strip between described outer jacket and external insulation layer；The tensile core being internally provided with dacron thread braiding composition of described outer jacket.
Described conductor is layered by many thin tinned copper wires, repeatedly, in the same direction bundle be stranding into.
Described reinforcing strip uses nylon tape.
The outer surface of described outer jacket is provided with heat loss through radiation High tailored coating layer.
After using said structure, compared to the prior art this utility model has the advantage, that this utility model simple in construction, pass through inner insulating layer, make that there is excellent electrical insulation properties and high-low temperature resistant, external insulation layer has excellent physical mechanical performance and high-low temperature resistant, high flame resistance, solves insulating properties and a difficult problem that high flame retardant can be taken into account；Setting up reinforcing strip between external insulation layer and outer jacket, the inside of outer jacket is provided with tensile core, improves the tensile strength of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, the most therefore limits protection domain of the present utility model, further illustrates this utility model with embodiment below in conjunction with the accompanying drawings.
Embodiment, as shown in Figure 1, a kind of photovoltaic cable, including conductor 10, conductor 10 be layered by many thin tinned copper wires, restraint repeatedly, in the same direction and be stranding into；The outer surface of conductor 10 is enclosed with insulating barrier, insulating barrier includes inner insulating layer 11 and external insulation layer 12, inner insulating layer 11 uses cross-linking radiation polyolefine material, by the crosslinkable polyolefin base material of 90%, inner insulating layer 11 adds that other anti-aging, assistant crosslinking agent and the processing aids of 10% form so that have excellent electrical insulation properties and high-low temperature resistant.External insulation layer 12 uses irradiation cross-linking flame-retardant polyolefine material, has excellent physical mechanical performance, high-low temperature resistant and high flame resistance, solves insulating properties and a difficult problem that high flame retardant can be taken into account.This insulating barrier uses special double-deck system of processing manufacture simultaneously, it is ensured that the one of insulation system, homogenizing and high prescription.External insulation layer 12 is cladded with, equipped with outer jacket 13, being provided with reinforcing strip 14 between outer jacket 13 and external insulation layer 12, and reinforcing strip 14 uses nylon tape；The tensile core 15 being internally provided with dacron thread braiding composition of outer jacket 13, improves the tensile strength of cable, and improves the mechanical performance of cable.The outer surface of outer jacket 13 is provided with heat loss through radiation High tailored coating layer 16, the effect of object heat insulating water-proof can be radiated away, it can walk be painted the heat on object to airspace autoemission with 8-13.5 μm infrared wavelength, reduces support body outer surface and internal temperature, and radiating and cooling is obvious.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this utility model, although this utility model being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
