The YJV three-core XLPE cable serves 6–35 kV transmission and distribution. Compacted copper conductors are insulated with super-clean XLPE and screened with copper tape; the three cores are assembled, rounded with filler and oversheathed in PVC or PE. With stable insulation, high heat resistance and large capacity, it is used in urban grid upgrades, industrial distribution and municipal projects, buried direct or laid in trays and trenches.
