Abstract

As the most important problem for crosslinked polyethylene (XLPE) insulated power cable, the nature of water treeing has been studied with great efforts. And recently, some insulating materials to be watertree resistive have been proposed. However, the substantial mechanism of water treeing has been left still unclarified in spite of the importance of complete suppression of water treeing. In this paper, the nature and morphology of XLPE with o r without water tree were examined by means of analytical instruments tnd the influence of contack with certain fluids on water treeing without water was investigated. A theoretical mechanism on water treeing will also be discussed.

一种新的化学方法来水树在聚乙烯绝缘
交联聚乙烯(XLPE)绝缘电力电缆的主要问题是疏水性能的研究。近年来,人们提出了一些耐水绝缘材料。然而,尽管完全抑制水树的重要性,但水树的实质机制仍未明确。本文用分析仪器对无水和无水交联聚乙烯的性质和形貌进行了研究,并探讨了与特定流体接触对无水交联聚乙烯的水树形的影响。本文还讨论了水树的理论机理。
