- No armour, no screen

Scope of Application / Usage Range
ZC-YJV 0.6/1 kV 2×10 mm² is for fixed installation in LV distribution up to 1.2 kV where flame-retardant Class C is required (plain YJV is not sufficient).
Typical use:
- Single-phase AC circuits (L+N) or DC pairs (+,−) in buildings with fire-code requirement for ZC
- Indoor distribution boards, residential/commercial final circuits, lighting & small equipment feeders
- Cable trays, ducts, trenches, shafts in high-rise buildings, hotels, stations, metros, hospitals, data centres (where ZC or better is specified)
- Industrial plants, warehouses, PV/battery/charger branch circuits (DC polarity check needed)
- Direct buried in non-aggressive soil, low mechanical risk

Not suitable for:
- Fire-survival circuits → use NH-ZC-YJV 2×10
- Heavy mechanical load → use ZC-YJV22 2×10
- Three-phase → use 3-core / 4-core
- Magnetic conduit AC run (eddy risk, though less critical at 10 mm²)
- Corrosive/oily environment without extra barrier
Packing
- Drum / coil: Steel-wooden drum or coil, 100–500 m typical.
