types of solar cable
Solar cables are the key to photovoltaic installations, large installations of solar farms, or small installations of homeowner solar systems. The characteristics of solar cables are determined by the special insulation and sheath material of the cable, which we call cross-linked polyethylene. Heute, ZMS Cable will show you how to choose the right solar cable.
Die Ummantelung herkömmlicher Kabel hat eine schlechte Anti-Ultraviolett-Leistung, was zur Alterung des Kabelaußenmantels führt. Der Unterschied zwischen Solarkabel und gemeinsame Kabel besteht hauptsächlich aus den Materialien Isolierung und Mantel.
Die in Solarkabeln verwendeten Materialien sind bestrahlte Materialien, which are resistant to high temperatures, ultraviolet rays, und Umweltschutz.
Nach Bestrahlung durch einen Bestrahlungsbeschleuniger, die Molekularstruktur des Kabelmaterials verändert sich, wodurch seine Leistung in allen Aspekten erbracht wird.
In der Tat, während der Installation und Wartung, Kabel können an scharfen Kanten von Dachkonstruktionen verlegt werden, während Kabel unter Druck stehen, biegen, Spannung, cross-tensile loads, and strong shocks.
If the cable jacket ist nicht stark genug, die Kabelisolierung wird stark beschädigt, die Lebensdauer des gesamten Kabels beeinträchtigen, oder Probleme wie Kurzschlüsse verursachen, Feuer, and personal injury hazards.
While you are about to invest in solar cable, Es gibt mehrere Dinge, die Sie beachten müssen.
Eine Sache, die Sie berücksichtigen müssen, ist, wann Sie das Solarkabel verwenden möchten. You must make certain the cable is certainly going to be strong enough to suit your needs, and that means that you need to understand the exact amount of weight that you simply plan to build using the solar cable.
Sie sollten auch erfahren, wie weit Sie die Art des Materials bewegen möchten. Nicht nur das, but you are able to customize the type, so you have to know ahead of place where place the type should be.
Außerdem, you also need to examine such things as the maintenance requirements and precisely what the cable is created away from.
You might want to look into cables that are easy and portable to transport so that you don’t need too much trouble maintaining them.
Pricing is another significant consideration in regard to buying your cables.
You desire to make sure that the price of the cable suits your budget, and you also want to make certain you will not be paying an excessive amount for your solar cable. Wenn Sie sich die Zeit nehmen, die richtige Recherche durchzuführen, wird es sich auszahlen, wenn Sie den besten Preis finden.
The selection of cables for photovoltaic power generation follows the general requirements for cable selection.
Das ist, in accordance with the voltage level, to meet the continuous operation of the allowable current, short-circuit thermal stability, allowable voltage drop, economic current density, and laying environmental conditions factors such as selection.
Zur selben Zeit, photovoltaic power generation has its own characteristics, solar energy systems are often used in harsh environmental conditions, such as high temperatures, cold and ultraviolet radiation.
(1) Insulation properties of solar flexible cables.
(2) The heat resistance and flame retardant properties of the cable.
(3) The cable’s moisture-proof, light-proof (Anti-Strahlung).
(4) Cable laying mode.
(5) Cable conductor materials (Kupferkern, aluminum alloy core); (6) Cable conductor materials (Kupferkern, aluminum alloy core).
(6) Specification of cable cross-section.
You also need to consider whether to choose PV AC cables or PV DC cables.
(1) The series connection cable between components and modules, this part should use a special cable with PV certification 9.
(2) Parallel cables between strings and between their strings to the DC distribution box (convergence box), which may optionally use rare earth aluminum alloy conductor cables.
(3) The PV wire between the DC distribution box to inverter, this part can also choose to use rare earth aluminum alloy conductor cable.
The above cables are all DC cables, which are laid more outdoors and need to be moisture-proof, sunproof, kältebeständig, heat-resistant, UV-beständig, and some special environments need to be protected against acid and alkali, and other chemical substances.
The connecting cables between components are usually supplied in sets with the components.
(1) Connection cable from inverter to step-up transformer.
(2) Connection cable from the step-up transformer to the distribution unit.
(3) Connection cable from the distribution unit to the grid or the user.
The focus here is on the selection and laying of DC cables for grid-connected PV power generation Q. The principles are also applicable to some other types of photovoltaic power generation projects. PV power generation projects.
Vericable is a professional photovoltaic cable manufacturer, if you need PV installations that require high-quality cables, hope this was helpful. Weitere Informationen finden Sie unter unsere Webseiten.
