热塑性电力电缆绝缘材料:历史与发展
Thermoplastic Insulation Materials for Power Cables: History and Progress
摘要
Abstract
Power cables insulated by cross-linked polyethylene (XLPE) have been widely used in power transmission and distribution because of the excellent mechanical, thermal and dielectric properties of the insulation. However, the thermoset nature results in super low recycling capability of XLPE insulation out of service. In addition, the byproducts of cross-linking also lead to negative influence on the cable properties and health of workers. These factors call for and drive the development of thermoplastic cable insulation. We introduced the basic requirements of electrical properties of power cable insulation and summarized the structure-property relationship of low density of polyethylene (LDPE), high density of polyethylene (HDPE) and polypropylene (PP), which can be possibly used as thermoplastic cable insulation. Emphasis was given on the roles of polymerization, copolymerization, blending, additives, nanoparticles and chemical modification in tailoring the structure and property of thermoplastic insulating materials. Finally, the perspectives on the development of thermoplastic insulation materials were presented from the viewpoints of structure-property relationship of power cable insulation, multi-structure of the same type of polymer, and the rapid development of the polymerization techniques of polymers. It is suggested that the new polymerization techniques are the powerful strategy for realizing the high performance of thermoplastic power cable insulating materials, and the strategies of composite and modification are also important supplements.关键词
