Overview of Standards and Specifications for Polypropylene Insulation Power Cables and Its Materials in China

Polypropylene insulation power cables have been widely concerned in related fields at home and abroad because of their excellent electrical properties, eco-friendly and recyclable features. With the popularization and application of polypropylene cables, several standards and specifications for polypropylene cables and their materials have been formed. In view of a number of group standards on thermoplastic polypropylene cables and polypropylene cable materials published by domestic industry, the test items, conditions and requirements of each normative documents were compared, the problems concerned were discussed in the engineering application of polypropylene cables, and the research directions for standardization process of polypropylene cables were proposed. These could provide reference and guidance for more scientific and standardized development of polypropylene cables system in the future.
