北京朝阳电缆厂分析电缆耐温等级,在国标、美标、欧标中有啥不同?

北京朝阳电缆厂彩票大赢家分析电缆耐温等级,在国标、美标、欧标中有啥不同?


北京朝阳电缆厂电线电缆的设计、选材、生产、销售过程中,往往碰到很多温度参数,如90℃、105℃、125℃、150℃等。这些参数在行业中的通俗名称都叫耐温等级参数,那这些参数是怎么来的呢?同是90℃的耐温等级的材料,为什么老化温度不一样呢?老化温度和耐温等级是什么关系?绝缘允许的导体长期最高工作温度是怎么定义的?什么是温度指数?什么是材料的额定温度?硅烷交联料能满足125℃的耐温等级吗?


北京朝阳电缆厂指出要回答上述问题,首先要了解标准体系,因为不同的标准体系对耐温等级的定义是不同的。我们常见的标准体系主要有国家标准(及行业标准)、UL标准、EN/IEC标准等。

在IEC标准中,传统的电力电缆、建筑用线甚至太阳能电缆的设计导体长期最高工作温度都不会超过90℃,但并不代表用于此类电缆的材料允许的长期最高工作温度不能大于90℃。也不能说辐照交联料可以达到125℃的耐温等级,而硅烷交联料不能达到125℃的耐温等级,这样的表述是没有道理的。
