摘要
电缆中线芯导体的长期载流发热和外界环境因素的影响会导致护套和绝缘材料老化以至最终失效,因此,人们对其环境适应性研究也越来越重视。探讨了电缆的失效行为和机理,并据此总结了目前常用的环境适应性试验方法和评价方法。
With the calorific effect of extended electric current in the conductive cores and the influence of environmental factors, the insulating and sheathing material of cables may age, and ultimately fail. The research of its atmosphere environmental adaptation gets more attention. The failure behavior and mechanism of cables are discussed. Commonly used tests and evaluation methods are summarized.
