Abstract

Environmental protection is the future trend of power equipment development, and is also a research hotspot in the field of power cable insulation in recent years. Due to the excellent electrical properties and recyclability, polypropylene (PP) based composites are regarded as promising insulating materials for eco-friendly next-generation power cables. However, the high modulus and hardness of pure PP make it difficult to be directly employed as cable insulations, which needs to be further optimised. General methods of mechanical performance regulation often result in the deterioration of electrical performance, such as breakdown strength, space charge and so on. Therefore, it is recognised that the major challenge impeding practical applications of PP power cable insulation arises from the synergetic regulation of multi-performances. The multi-level structures influencing the multi-performances of PP are introduced by the authors and the researches on the performance enhancement of PP through nanoscale structure regulation in recent years are reviewed in detail. Seven kinds of modification methods including nano-doping, chemical grafting, in-suit copolymerisation, heat treatment, nucleating agent, voltage stabiliser and elastomer blending are paid special attention. Based on the full understanding of the research status, the challenges and issues of future research are put forward for eco-friendly PP power cable insulation.

环保聚丙烯电力电缆绝缘:现状与展望
环保是电力设备发展的未来趋势,也是近年来电力电缆绝缘领域的研究热点。聚丙烯(PP)基复合材料具有优异的电性能和可回收性,被认为是环保的下一代电力电缆绝缘材料。然而,纯PP的高模量和硬度使其难以直接用作电缆绝缘,这需要进一步优化。一般的机械性能调节方法往往会导致电气性能的恶化,如击穿强度、空间电荷等。因此,人们认识到阻碍PP电力电缆绝缘实际应用的主要挑战来自多种性能的协同调节。介绍了影响聚丙烯多种性能的多层结构,并对近年来通过纳米结构调控提高聚丙烯性能的研究进行了综述。重点介绍了纳米掺杂、化学接枝、嵌套共聚、热处理、成核剂、电压稳定剂和弹性体共混等7种改性方法。在充分了解研究现状的基础上,提出了环保型PP电力电缆绝缘今后研究的挑战和问题。
