目前,聚合物作为结构材料用于输配电系统的高电压户外绝缘子。在早期,户外绝缘子用陶瓷和玻璃材料制造。近年来聚合物绝缘子取得了发展,同时,设计和制造技术的进步使其越来越受到欢迎。此外,与陶瓷和玻璃绝缘子相比,聚合物绝缘子介电性能好,重量轻,成本低。选取绝缘子时要从材料性能和设计两方面考虑。在全球电力工业,人们愈来愈关注在严重污染环境中材料的降解过程和聚合物绝缘子的性能。 Currently, polymers are used as structural materials for high voltage outdoor insulators in power transmission and distribution systems. In the early days, outdoor insulators were made of ceramic and glass. Polymer insulators have gained momentum in recent years, and advances in design and manufacturing technology have made them more and more popular. In addition, compared with ceramic and glass insulators, polymer insulators dielectric properties, light weight, low cost. Select the insulator from the material properties and design considerations. In the global power industry, people pay more and more attention to the degradation of materials and the performance of polymer insulators in heavily polluted environments.
