Taking you to understand the photovoltaic cable and selection principles
Photovoltaic power generation systems can generate electricity by using solar energy, reducing fuel consumption and reducing energy waste. Speaking of photovoltaic power generation system, photovoltaic cable is the basis of supporting electrical equipment in photovoltaic system, so it is an indispensable part, may not be understood by everyone, the following is the introduction and selection of some photovoltaic cables organized by Guangdong Jiaxin Company, hoping to help you.
01 What is a photovoltaic cable?
Photovoltaic cable, that is, photovoltaic special cable, mainly used in photovoltaic power stations, the conductor part of tin-coated soft copper wire, insulation layer, sheath using radiation cross-linked polyolefin plastic, with high temperature resistance, cold resistance, oil resistance, anti-aging, anti-ultraviolet, environmental protection and other characteristics, mainly used in the environment of harsh climate conditions. Its characteristics are determined by its cable special insulation material and sheath material, which we call cross-linked PO.
02 The selection principle of photovoltaic DC cable
The cable used in the low-voltage DC transmission part of the solar photovoltaic power generation system, because the use of the environment and technical requirements are different, there are different requirements for the connection of different parts, the overall factors to consider are: The insulation performance of the cable, the heat and flame retardant performance of the cable, the moisture, cold and weather resistance of the cable, the laying method of the cable, the type of the cable core (copper core, aluminum core), the size of the cable, etc., taking into account the output current of the DC connector and the photovoltaic module, the current commonly used photovoltaic DC cable is PV1-F1*2.5mm2, PV1-F1*4mm2, PV1-F1*2.5mm2. PV1-F1*6mm2, etc.
