Description

太阳能光伏电缆
技术领域
本发明属于电缆领域， 尤其是一种应用于光伏太阳能系统的太阳能光伏电 缆。
背景技术
能源是人类赖于生存与发展的基本资源， 随着社会的进歩、 科技的发展， 常规资源消耗日益增大， 可利用能源的储量却越来越少。 而取之不尽， 用之不 竭的绿色环保能源- --一太阳能， 已经引起人们极大的兴趣。
21世纪， 各国政府特别是欧洲为了推动太阳能行业的发展，采取政府补贴、 资助等一系列鼓励政策， 加上人们环保意识日益增强， 太阳能产业大约以 40% 的速度递增， 在未来几年内将继续保持快速递增的强劲势头。
太阳能光伏电缆在北美市场销售必须符合 UL的相关标准;在欧洲市场销售 必须符合德国莱茵 TUV公司的技术规范 2PfG 1169/08.2007的要求。但在实际的 生产与应用中， 为了满足 UL的相关标准就无法满足德国莱茵 TUV公司的技术 规范 2PfG 1169/08.2007的要求， 因为 UL的相关标准主要指标是阻燃性和绝缘 性， TUV主要指标是电缆寿命、 热老化和无卤性， 然而在国际上还没有一种材 料作为绝缘层可以同时满足 UL和 TUV的要求， 所以如果产品只能满足一个要 求， 就限制了产品的销售区域。 因此同一种光伏电缆产品无法在两大市场同时 销售， 或者只能针对两大市场进行分开销售两种不同的产品， 这样不仅增加了 企业的研发成本和生产成本， 而且不利于光伏组件的研发。 太阳能光伏电缆主 要用于太阳能光伏组件的接线盒内， 世界上各大生产接线盒的公司针对现有的 接线盒都在改进， 尤其是将接线盒的体积减小、 重量减轻， 由于太阳能光伏电 缆是接线盒的主要零部件之一， 所以现有的太阳能光伏电缆的外径、 重量直接 制约着接线盒的改进。
发明内容

所述的导体同一截面最大外径与最小外径之差与平均外径比值小于等于 15%。
所述的护套的厚度为 0.5mm至 1.5mm。 护套与导体及绝缘层结合时保证了 太阳能光伏电缆的整体外径的减小。
所述的退火软铜丝或铍锡退火软铜丝的单丝最小伸长率 为 20%，其最大单 丝外径为 0.41mm。
