标准摘要
[中文适用范围]： 本标准规定了评定聚乙烯(PE)和交联聚乙烯(XLPE)复合物中水树枝化的试验方法，即评定这些复合物在交流(AC)电应力和水存在卜的相关性能。标准中叙述丁两种试验方法，方法J用厂评定单独绝缘材料，方法Ⅱ用于评定覆有半导电屏蔽层的绝缘复合物的绝缘夹层。 [外文原描述]： Prescribes methods of test for the evaluation of water treeing in polyethylene (PE) and crosslinked polyethylene (XLPE) compounds, as a means to assess their relative performance under alternating (a.c.) electric stress, in the presence of water. Two methods are described, method I covering the evaluation of insulating materials alone, and method II covering the evaluation of insulating sandwiches consisting of an insulating material in intimate contact with semiconducting screens.
