Abstract: According to the requirements of relevant standards for the volume resistivity of conductor shielding and insulation shielding, the volume resistivity of conductor and insulation shielding made from two imported shielding compounds and one domestic shielding compound was investigated. Cable core samples were prepared using the three shielding compounds with cross-linked polyethylene (XLPE) insulating material, respectively. The volume resistivity of the conductor shielding and insulation shielding was measured, and the production performance of different shielding compounds was analyzed. The results showed that the three shielding compounds exhibited no significant differences in processing performance and product appearance. At 90 °C, the volume resistivity of the conductor shielding and insulation shielding of the three samples showed no significant differences, and for the same cable core sample, no significant difference was observed between the volume resistivity of the conductor shielding and that of the insulation shielding; all values met and exceeded the standard requirements. It was concluded that when the same shielding compound was used for both the conductor shielding and insulation shielding of a cross-linked cable core, no significant difference in volume resistivity was observed between them. The results provided a reference for shielding material selection, process improvement, and standard revision.
