Kommunikasie & Beheer kabel
ZMS manufactures a comprehensive range of communication & control cable for solar system. These high-quality cables ensure seamless data transfer and efficient system management, as well as precise power distribution and operational control.
Communication cables in a solar power system facilitate data transfer between components such as solar panels, omsetters, and monitoring systems, enabling real-time performance monitoring, remote control, and diagnostics. ZMS can provide singlemode or multimode fiber optic cables with the required terminations as well as shielded twisted pair cables.
Control cables manage power distribution and operational control within a solar power system by transmitting control signals to components like inverters, trackers, and relays. They ensure proper execution of operational commands, safety mechanisms, and synchronization of multiple system parts. ZMS control and instrumentation cables can maintain the efficiency and reliability of PV systems by coordinating power regulation and providing protective functions.
ZMS Communication Cable
Single Mode Fiber Optic Cable
ZMS’s single mode fiber optic cables are engineered for long-distance data transmission with minimal signal loss, making them ideal for connecting SMU loops to inverter stations and linking inverter stations to SCADA rooms. These cables provide high bandwidth and low attenuation, ensuring reliable and high-speed communication essential for real-time monitoring and control in solar energy systems.
Multimode Fiber Optic Cable
ZMS offers multimode fiber optic cables designed for shorter-distance data transmission within solar energy systems. These cables are perfect for connecting various components within an inverter station, providing robust performance and high data transmission rates. The multimode design allows multiple signals to be sent simultaneously, enhancing the efficiency and reliability of your solar power system.

Gereelde vrae
Beïnvloed kommunikasiekabels die akkuraatheid van sonkragopwekkingstelseltelling?
In 'n sonkragopwekkingstelsel, the primary role of communication cables is to transmit control signals and monitoring data, such as power output, system status, fault alarms, and other information. These cables do not directly participate in the transmission of electrical energy. Daarom, communication cables themselves do not directly affect the accuracy of the counting in a solar power generation system.
Egter, if communication cables experience faults (such as signal attenuation, interference, or disconnections), it may lead to the monitoring system being unable to accurately receive or transmit data, thereby affecting the precision and timeliness of system monitoring. Byvoorbeeld, data transmission delays or errors might prevent maintenance personnel from promptly understanding the actual operational status of the power generation system or lead to inaccurate data recording, thus impacting the statistics and analysis of power generation.
Daarom, while communication cables do not affect the actual production of electrical energy, they are crucial for the effective management and maintenance of the system. This indirectly relates to the overall performance evaluation and efficiency optimization of the solar power generation system. Ensuring the quality and proper maintenance of communication cables is essential for maintaining reliable monitoring and efficient operation of the solar power generation system.
Watter soorte kabels is nodig vir sonkragstelsels?
As 'n deurslaggewende komponent van volhoubare energie-oplossings, die veilige en doeltreffende werking van sonkragopwekkingstelsels berus op die toepaslike konfigurasie en gebruik van verskeie gespesialiseerde kabels. Die tipes kabels wat in 'n sonkragopwekkingstelsel benodig word, sluit die volgende in:
Sonkrag DC kabel
Hierdie kabels is spesifiek ontwerp om fotovoltaïese modules aan te sluit (sonpanele) en vir kragoordrag tussen modules na die GS-kombinasiekas. Gegewe hul direkte blootstelling aan buitelugomgewings, hulle moet die volgende eienskappe besit:
- UV Weerstand: Om prestasie-agteruitgang as gevolg van langdurige sonblootstelling te voorkom.
- Weerweerstand: Om verskeie weerstoestande te weerstaan, insluitend uiterste temperature, humiditeit, en windverwaaide sand.
- Soutsproei-korrosiebestandheid: Geskik vir kusgebiede om soutskade te voorkom.
- Vlamvertraging: Om brandrisiko's te verminder en stelselveiligheid te verbeter.
- Meganiese sterkte: Om installasie en omgewingsdruk te verduur sonder om maklik beskadig te word.
AC kabel
AC-kabels word by die omskakelaar-uitsetpunt gebruik om die omgeskakelde AC-krag na die AC-verdeelbord of direk na die rooster oor te dra. Hierdie kabels moet aan netwerkverbindingstandaarde voldoen en oor goeie isolasie-eienskappe en hittebestandheid beskik om veilige en doeltreffende kragoordrag te verseker.
Data kommunikasie kabel
In 'n sonkragopwekkingstelsel, datakommunikasiekabels dien as die inligtingsbrug. Hulle stuur nie net die elektriese data wat deur die fotovoltaïese skikking gegenereer word nie, maar dra ook intydse statusinligting van omsetters en ander moniteringstoerusting oor na die sentrale moniteringstelsel via bedrade of draadlose netwerke (insluitend optiesevesel) vir stelseloptimalisering en foutdiagnose.
Beheer kabel
Beheerkabels word gebruik om beheerders aan te sluit, omsetters, en ander hulptoerusting binne die stelsel, geoutomatiseerde beheer en effektiewe monitering te verseker. Hierdie kabels moet goeie seinoordragstabiliteit en anti-interferensievermoë hê om akkurate uitvoering van beheeropdragte te verseker.
Aarding kabel
Grondkabels speel 'n kritieke rol in die veiligheidsbeskerming van die hele sonkragopwekkingstelsel. Hulle bied 'n lae-weerstand pad om weerligstrome of stelselfoutstrome vinnig te ontlaai, voorkoming van elektriese skokke en skade aan toerusting, om sodoende die veiligheid van personeel en toerusting te verseker.
Oorhoofse kabel
In sekere installasie scenario's, soos langafstandtransmissie of terreinbeperkings, oorhoofse kabels word gebruik vir netwerkverbinding van die sonkragopwekkingstelsel. Hierdie kabels moet spesiaal ontwerp word om eksterne fisiese skade en klimaatsfaktore te weerstaan, terwyl goeie geleidingsvermoë en meganiese sterkte behou word..
By die keuse van hierdie sonkragkabels, dit is noodsaaklik om nie net hul eienskappe en toepaslike omgewings in ag te neem nie, maar ook om te verseker dat alle kabels en bykomstighede voldoen aan plaaslike elektriese veiligheidstandaarde en industrieregulasies om die langtermyn stabiele werking en voldoening van die sonkragopwekkingstelsel te verseker.
Watter persentasie van die totale konstruksiekoste verteenwoordig kabels in 'n fotovoltaïese kragstasie?
Die koste van kabels in 'n fotovoltaïese (PV) kragstasie verteenwoordig tipies rondom 10% van die totale konstruksiekoste. Hierdie persentasie kan wissel op grond van verskeie faktore soos die omvang van die projek, toerusting seleksie, streeksverskille, en markskommelings. Volgens sommige skattings:
- Fotovoltaïese modules (sonpanele) rekening vir ongeveer 50% van die totale toerustingkoste.
- Omsetters en ander elektriese toerusting is verantwoordelik vir ongeveer 10%.
- Kabels en monteerstrukture is elk verantwoordelik vir ongeveer 10%.
Daarom, kabelkoste maak oor die algemeen ongeveer uit 10% van die totale konstruksiekoste. Egter, dit is 'n rowwe skatting, en die werklike verhouding kan wissel na gelang van die spesifieke begroting en materiaalpryse van 'n projek. Daarbenewens, met vooruitgang in tegnologie en markveranderinge, hierdie persentasie kan onderhewig wees aan aanpassings.
