Research Progress on the Application of Graphene in Cable Materials

Cable materials encompass a diverse array of components, including metal conductors, semi-conductive shielding materials, the preferred insulating elements of cables, and cable accessory insulation materials, in addition to other related components. The performance of cable conductor materials has a direct impact on the amount of current that can be carried and the transmission loss. Consequently, the development of high-conductivity cable conductor materials represents the current primary research focus of the cable industry. Given its exemplary conductivity and substantial mechanical strength, graphene represents a pivotal material for enhancing the conductive attributes of copper conductors. Moreover, conventional cable semiconducting shielding materials are typically enhanced in conductivity through the incorporation of carbon black. Similarly, graphene has the potential to serve as a viable alternative for improving the conductivity characteristics of semiconducting shielding materials. This paper presents a study of the application of graphene in cable materials, with a particular focus on its role in enhancing the conductive properties of copper cable conductors and semiconducting shielding materials. This thesis begins with a comprehensive examination of graphene’s electrical and mechanical properties, emphasizing its remarkable performance. It then explores the use of graphene in cable materials and the potential applications for graphene cables. The objective of this paper is to serve as a reference point for the advancement of high-performance cable materials based on graphene research.
