北京朝阳电缆厂电缆耐温等级分析。国家标准、美国标准和欧洲标准有什么区别?


电线电缆的设计、选材、生产和销售过程中,经常会遇到许多温度参数,如90(?),105(?),125(?),150(?)工业上的这些参数通常被称为耐温等级参数,北京朝阳电缆厂彩票大赢家那么这些参数是如何产生的呢?为什么相同耐温等级的材料的老化温度不同?老化温度与耐温性有什么关系?绝缘导线的最大长期工作温度的定义是什么?温度指数是多少?材料的额定温度是多少?硅烷交联材料能满足125℃的耐温水平吗?

那么硅烷交联交联交联交联聚乙烯能达到125℃的耐温水平吗?更严格的答案应该是,硅烷交联交联交联交联聚乙烯可以达到UL标准规定的125的额定温度,因为在UL 1581第40章绝缘和护套材料的一般规则中,已经明确提出材料的化学成分应不受管制。交联聚乙烯导线的长期最高工作温度能否达到125C,关系到电缆的设计寿命及其应用情况。目前还没有相关数据对交联聚乙烯导线寿命进行系统评价。从短期老化可以推断,如果电缆的设计寿命为25年,允许导体的长期最高温度当然可以大于90 C。在IEC标准中,传统电力电缆导体的长期最高工作温度为施工电缆,甚至太阳能电缆都不会超过90摄氏度,但这并不意味着电缆所用材料的允许长期最高工作温度不能超过90摄氏度,不能说辐照交联材料能达到125摄氏度的耐温性。等级,而硅烷交联材料不能达到125℃的耐温等级。这种说法是不合理的。
