This standard specifies the usage characteristics, product codes, markings and examples of irradiation cross-linked halogen-free low-smoke flame-retardant polyolefin insulated and sheathed photovoltaic cables for slope applications with rated voltage AC U0/U of 0.6/1kV and DC of 900V. , technical requirements, finished cables, test conditions, test items and test methods, delivery length, marking, packaging, transportation and storage. This standard is applicable to slopes such as mountains and hills that require cables to be short-distance and low-altitude overhead and resistant to ozone, acid and alkali, salt spray and environmental climate. The rated voltage AC U0/U is 0.6/1 kV and the DC DC is 900V. Use photovoltaic cables. This standard applies to the series cables between photovoltaic modules and modules on the DC side of photovoltaic power generation systems, between strings and between strings and DC distribution boxes.
