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. Sot, ZMS Cable will show you how to choose the right solar cable.
Karakteristikat e kabllove diellore
Mbulesa e kabllove të zakonshme ka performancë të dobët kundër ultravjollcës, gjë që çon në plakjen e mbështjellësit të jashtëm të kabllit. Dallimi midis kabllot diellore dhe kabllot e zakonshme është kryesisht në materialet e izolimit dhe këllëf.
Materialet e përdorura në kabllot diellore janë materiale të rrezatuara, which are resistant to high temperatures, ultraviolet rays, dhe mbrojtjen e mjedisit.
Pasi rrezatohet nga një përshpejtues i rrezatimit, struktura molekulare e materialit kabllor do të ndryshojë, duke siguruar kështu performancën e tij në të gjitha aspektet.
Në fakt, gjatë instalimit dhe mirëmbajtjes, kabllot mund të kalohen në skajet e mprehta të strukturave të çatisë, ndërsa kabllot i nënshtrohen presionit, përkulje, tensioni, cross-tensile loads, and strong shocks.
If the cable jacket nuk është mjaftueshëm i fortë, izolimi i kabllove do të dëmtohet rëndë, duke ndikuar në jetën e shërbimit të të gjithë kabllos, ose duke shkaktuar probleme të tilla si qark i shkurtër, fire, and personal injury hazards.
Përgatituni për projektin e kabllove diellore
While you are about to invest in solar cable, ka disa gjëra që duhet të keni parasysh.
Një gjë që duhet të keni parasysh është kur dëshironi të përdorni kabllon diellore. 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.
Ju gjithashtu duhet të mësoni se sa larg keni ndërmend të lëvizni llojin e materialit. Not only that, but you are able to customize the type, so you have to know ahead of place where place the type should be.
Për më tepër, 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. Marrja e kohës për të bërë kërkimin e duhur do të paguajë shumë sa herë që të gjeni çmimin më të mirë.
Basic principles of solar cable selection
The selection of cables for photovoltaic power generation follows the general requirements for cable selection.
Kjo eshte, 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.
Në të njëjtën kohë, 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 (kundër rrezatimit).
(4) Cable laying mode.
(5) Cable conductor materials (bërthama e bakrit, aluminum alloy core); (6) Cable conductor materials (bërthama e bakrit, aluminum alloy core).
(6) Specification of cable cross-section.
You also need to consider whether to choose PV AC cables or PV DC cables.
Kabllot PV DC
(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, rezistente ndaj të ftohtit, heat-resistant, rezistente ndaj UV, 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.
Kabllot PV AC
(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. Mund të gjeni më shumë informacion mbi faqet tona të internetit.
