Overview
The Hongce Cable YJV22 8.7/15kV Power Cable offers high-efficiency electricity distribution for industrial and utility infrastructure. Built to IEC 60502-2, it ensures reliable 15kV power transmission in tough environments. Electrical Performance Featuring Class 2 stranded copper conductors, it minimizes power loss. High-grade XLPE insulation supports continuous 90°C operation and withstands 250°C short circuits. Semi-conducting screening and copper tape shielding eliminate partial discharge risks. Rugged DSTA Armor Double steel tape armor (DSTA) over PVC bedding shields inner cores from heavy mechanical impacts, soil loads, and rodent bites. This allows safe direct underground burial without extra piping. Wide Application Ideal for power plants, substations, urban grids, and mining areas, delivering long-term stability and reduced maintenance.
