A four-core WDZ-YJY 3×150+1×70 mm² cable — three phase cores plus a neutral — for three-phase four-wire distribution. XLPE insulation allows 90 °C continuous and 250 °C short-circuit conductor temperature, giving high capacity and low loss. The halogen-free flame-retardant polyolefin oversheath passes bunched burning tests and resists flame spread, buying time for evacuation and rescue.
