高压电缆是城市输电网的关键电力装备,是海上风电输送到陆地电网、实现新能源大规模利用的关键电力装备。然而,高压电缆用交联聚乙烯绝缘料是我国高压电缆生产的“卡脖子”关键电工材料。高压电缆交联聚乙烯绝缘料的生产与应用全流程涉及多步骤、多结构、多性能。该文梳理高压电缆交联聚乙烯绝缘料的4个关键性能,凝练出高压电缆交联聚乙烯绝缘的5个基础科学问题。通过基础问题探讨,旨在推进我国高压电缆交联聚乙烯绝缘料基础理论的研究及自主研发进程。

High-voltage cable is the key power equipment for urban power transmission grids,as well as for the transmission of offshore wind power to the land power grid and the large-scale utilization of renewable energy.However,crosslinked polyethylene insulating material has become the bottleneck for the production of high-voltage cables in China.The entire process for the production and application of high-voltage cable crosslinked polyethylene insulating materials involves multiple steps,multiple structures,and multiple properties.In this paper,four key properties and five basic scientific issues of high-voltage cable used crosslinked polyethylene insulating materials were proposed.The purpose is to promote the research on the basic theory of high-voltage cable crosslinked polyethylene insulating material,as well as to promote the independent research and development of high-voltage cable crosslinked polyethylene insulating materials.
