NOVELTY - Insulating cable material comprises 70-80 pts. wt. polypropylene (PP), 20-30 pts. wt. elastomer, 0.1-0.5 pts. wt. antioxidant, 0.5-2 pts. wt. modified graphene and 1-5 pts. wt. nano silicon dioxide. USE - Used as insulating cable material. ADVANTAGE - The insulating cable material improves the space charge accumulation phenomenon at the interface DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing insulating cable material comprising adding the elastomer and modified graphene in the torque rheometer, melting and mixing for 8-10 minutes, adding PP and antioxidant, melting and mixing for 10-12 minutes, adding modified nano-particle melting and mixing for 3-5 minutes to obtain the insulating cable material.
