UL 854 和 UL 1893 认证是光伏 (PV) 电缆的重要标准,确保其满足严格的安全、性能和耐久性要求。这两项认证均由美国保险商实验室 (UL) 颁发,UL 是一家领先的独立安全机构,以其在评估电气产品方面的专业知识而享誉全球。这些认证专门针对太阳能发电系统中使用的电缆,这些电缆对于安全地将电力从太阳能电池板传输到逆变器、电网或储能系统至关重要。确保光伏电缆符合这些认证,即可保证其符合行业安全规范,并能承受太阳能装置中常见的恶劣环境。
UL 854认证专注于光伏系统中使用的中压(MV)电缆。具体而言,该认证适用于额定电压为600伏或以下的电缆,并验证这些电缆在住宅和商业太阳能装置中的使用安全性。UL 854标准对于安装在光伏板、接线盒和光伏系统其他组件附近的电缆尤为重要,因为电缆故障可能导致严重的安全隐患,例如短路或火灾。
UL 854认证流程确保电缆具备安全传输太阳能电池板所产生电力所需的电气性能。这包括确认其绝缘电阻、额定电压和载流能力是否符合标准。获得UL 854认证的电缆还会接受评估,以检验其承受物理磨损、极端温度、紫外线辐射和潮湿环境的能力,这些都是户外环境中常见的挑战。
