Why do solar photovoltaic power stations use specific solar photovoltaic cables?

The photovoltaic power station is a photovoltaic PV cable with the following characteristics: The high temperature and voltage resistance value reaches 1000V Corrosion resistance and weathering resistance The insulating layer is 2-3 times thicker than ordinary cables. The photovoltaic power station needs to determine the cable line according to the current value of the string The distributed power station uses a single string to directly connect the inverter in series. Generally, the current value of a single string does not exceed 9A, and the photovoltaic cable of 2.5mm2 or 4mm2 is used.

Concentrated photovoltaic power stations generally use centralized inverters, at least 100KW inverters. At this time, the string will pass through the DC combiner box and then connect to the inverter. At this time, the wire diameter is determined according to the current.

The solar photovoltaic cable centralized inverters generally used in centralized photovoltaic power stations are at least 100KW inverters. At this time, the string will pass through the DC combiner box, and then connect to the inverter. At this time, it will come and go according to the current. Determine the wire diameter.
