Abstract
The utility model discloses a single-core photovoltaic cable comprising an alloy conductor with a cross section of 1.0 to 260 square millimeters. A twisted structure of a plurality of tinned magnesium aluminum silicon alloy wires is employed by the alloy conductor, elongation at break of a single wire is not less than 18%, through extruding modification of cross-linked polyethylene outside the alloy conductor, an insulation layer is formed, a fire resistant layer is formed through winding a high temperature resistant polyester belt between the alloy conductor and the insulation layer, a reticular tensile layer which is woven by aramid belts and nylon belts is arranged outside the insulation layer, a sheath layer is formed through extruding modification of irradiation cross-linked fluorine rubber outside the tensile layer, and the irradiation cross-linked fluorine rubber of the sheath layer and the tensile layer form a whole body through extrusion. According to the single-core photovoltaic cable, a bending radius is smaller, the cable is more flexible and is suitable for laying in a narrow space, moreover the cable also has the advantages of thermal properties, mechanical properties and chemical properties for bearing pressure, bending, tension, cross tension load and strong impact, best wind and rain resistance property, ultraviolet light resistance and ozone erosion resistance.
Description
Technical field:
The utility model relates to the electric wire field, relates in particular to a kind of single core photovoltaic cable.
Background technology:
One of green energy resource technology that following heliotechnics will become, solar energy or photovoltaic application will be day by day extensive, and except the photovoltaic generation factory development rapidly that government supports, the private investor also just actively founds the factory.
Heliotechnics not only depends on efficient or the high-performance of solar components self, also be unable to do without the service cable system supporting with it.And these systems should have environmental stress resistance, anti-mechanical load and the performance such as high temperature resistant.To reduce because of maintenance and to safeguard the solar energy system expense.Improve the useful life of whole system.But existing cable can not satisfy above-mentioned requirements.
The utility model content:
For the prior art problem, the purpose of this utility model provides a kind of single core photovoltaic cable, is applicable to rated voltage 3kV and following direct voltage, can bear long-term work under adverse circumstances, and mechanical performance is superior.
The technical solution of the utility model is as follows:
Single core photovoltaic cable, it is characterized in that: comprise alloy conductor, described alloy conductor cross section is 1.0 ~ 260mm
2Alloy conductor adopts many zinc-plated Mg-Al-Si alloy skein silks to close structure, the single wire fracture percentage elongation is not less than 18%, outside alloy conductor, extrude modified crosslinking polyethylene and form insulating barrier, the flame retardant coating that wrapped high temperature resistance polyester band consists of between the alloy conductor of cable and insulating barrier, insulating barrier adopts aramid belt and nylon tape to weave webbed tensile layer outward, and tensile layer extrudes modification cross-linking radiation fluorubber outward and forms restrictive coating, and the cross-linking radiation fluorubber of restrictive coating and tensile layer form one through extrusion molding.
Described single core photovoltaic cable, it is characterized in that: the thickness of described tensile layer is not less than 2mm.
Compared with the prior art, the utility model beneficial effect is embodied in:
Conductor adopts the Mg-Al-Si alloy conductor in the utility model, and bending radius is less, and cable is more soft, is adapted at small space and lays; Insulation and sheath have adopted IXPE, cross-linking radiation fluorubber material, have to bear pressure, bending, tension force, be stretched across load and powerful weather resistance, UV resistant and ozone aggressivity of impacting thermal characteristic, mechanical property and chemical characteristic, the best; The design of tensile layer has promoted the tensile strength of cable under the less prerequisite of outside diameter of cable impact.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Single core photovoltaic cable comprises alloy conductor 1, and alloy conductor 1 cross section is 1.0 ~ 260mm
2Alloy conductor 1 adopts many zinc-plated Mg-Al-Si alloy skein silks to close structure, the single wire fracture percentage elongation is not less than 18%, 1 extrudes modified crosslinking polyethylene formation insulating barrier 2 outside alloy conductor, the flame retardant coating 3 that wrapped high temperature resistance polyester band consists of between the alloy conductor 1 of cable and insulating barrier 2, insulating barrier 2 outer employing aramid belts and nylon tape weave webbed tensile layer 4, the tensile layer 4 outer modification cross-linking radiation fluorubber that extrude form restrictive coating 5, and the cross-linking radiation fluorubber of restrictive coating 5 and tensile layer 4 form one through extrusion molding.
The thickness of tensile layer 4 is not less than 2mm.
