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？

在电线电缆的设计、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。
