Solar photovoltaic cable and general power cable What is the difference

_{Solar photovoltaic cables and ordinary cables are used to transmit current. The difference is that while transmitting current, the requirements for the use environment are different, and the materials and processes that make up the cable are different.}

_{Common photovoltaic cable models: PV1-F, H1Z2Z2-K, 62930IEC131, etc.}

_{Common common cable models: RV, BV, BVR, YJV, VV and other single-core cables}

_{First. The difference in usage requirements:}

_{1. The rated voltage is different}

_{Photovoltaic cable: 600/100V or new standard 1000/1500V;}

_{Ordinary cable: 300/500V or 450/750V or 600/1000V (YJV/VV series)}

_{2. Different adaptability to the environment}

_{Photovoltaic cables: need high temperature resistance, cold resistance, oil resistance, acid and alkali salt resistance, rain resistance, UV resistance, flame retardancy, environmental protection, and can be used in harsh environments with a service life of more than 25 years.}

_{Ordinary cables: generally used for indoor laying, buried pipes and electrical equipment connections, etc., have a certain temperature and oil resistance, but cannot be exposed outdoors and in harsh environments. The service life is generally based on actual conditions without special requirements .}

_{Second, the difference between raw materials and processing technology：}

_{1. Different raw materials}

_{Photovoltaic cable:}

_{Conductor: tinned copper wire conductor}

_{Insulation: cross-linked polyolefin insulation}

_{Sheath: cross-linked polyolefin insulation}

_{Ordinary cable:}

_{Conductor: copper conductor}

_{Insulation: PVC or polyethylene insulation}

_{Sheath: PVC sheath}

_{2. Different processing technology}

_{Photovoltaic cables: the outer skins are all cross-linked and irradiated}

_{Ordinary cables: generally do not undergo cross-linking radiation, YJV\YJY series power cables will be cross-linked}

_{Third, the certification is different:}

_{Photovoltaic cables generally require TUV certification, and ordinary cables generally require CCC certification or only require a production license.}
