Is the number based on the PV Cable size

 Whether large-scale photovoltaic power generation market, medium and small photovoltaic solar power station group, we need a variety of roughly the same cable, the number is based on the size. For the common cable is required to have excellent weather resistance, cold resistance and softness. That is what PV Cable producer considered.

Prefabricated cable connectors is very important part, so as to facilitate field installation, tailor-made prefabricated cable accessories, to determine based solely on the overall design. U.S., Japan and Germany have for photovoltaic (PV) systems using cable standards or specifications, this specification only points slightly Germany Introduction: German standard number 2Pfg 1169.08/2007, the test specification lists German Institute for Standardization (DKE) AK411. 23 working Group "PV system cable," the document requirements.

DC side of photovoltaic systems for flexible single-core flexible cables, the maximum allowable voltage of 1.8 kV DC conductor / conductor of the grounding system. The cable safety level II class. These cables can be connected by multi-core structure.Cable operating at ambient temperature to 90 ℃.
