Recyclable cable insulation, polymeric insulator, recyclable polymers, PP, LDPE, HDPE, XLPEAbstract
Global consumption of electrical cables continues to grow with increasing electrification and infrastructure projects. Cross-Linked Polyethylene (XLPE) has been used as a traditional non-recyclable insulating material for cable insulation for many years due to its good dielectric, mechanical, and thermal properties and economic viability. The volume of waste generated increases daily due to XLPE, which contributes to growing landfill sites. Recyclable insulation of electric cables is significant in promoting environmental sustainability and resource efficiency, akin to substantial advantages over XLPE. Additionally, recyclable materials help conserve non-renewable petroleum resources. This review article presents an overview of recyclable polymeric insulation materials that can be an alternative solution to XLPE. Recyclable polymeric materials like Polypropylene (PP), Low-Density Polyethylene (LDPE), High-Density Polyethylene (HDPE), and polyolefins are briefly discussed in this paper. PP and its blend composites and test results of electrical and mechanical properties are further explained.
