Emergency overload temp.: 105 °C (limited duration)
Min. ambient temp. during installation: 0 °C (pre-heat below 0 °C)
Service ambient temperature range: −20 °C to +90 °C (sheath/environment)
Flame retardant class: Category C per GB/T 19666 (bundled, self-extinguishing, char ≤ 2.5 m)
8. Mechanical & Installation Parameters
Minimum bending radius (unarmoured multi-core): ≥ 15 × overall diameter → ≈ 330 mm at Ø22 mm
Maximum pulling tension (copper conductor only): 50 N/mm² × 16 mm² × 5 = 4000 N total (distributed to all 5 cores)
PVC sheath pulling limit: significantly lower — avoid direct sheath grip; use conductor pulling sock
Direct burial: Allowed in non-aggressive soil; sand bed + warning tape, depth ≥ 0.7 m, conduit under roads
Conduit fill: Conduit ID ≥ 1.5 × cable OD → ≥ 33 mm (use 40 mm conduit or larger)
Cable tray / duct: 5-core is stiff; observe 15D bend radius to avoid core deformation
Elevation difference: No limitation for XLPE insulated cable
9. Material Specification Summary
Conductor: Cu ≥ 99.9 % annealed, Class 2, 7×1.70 mm, IEC 60228 / GB/T 3956
Insulation: XLPE, 0.7 mm nom., rated 90 °C (coloured per core function)
Filler: Flame-retardant PP/PE (ZC grade)
Binder: Flame-retardant glass fibre / FR tape
Outer sheath: Flame-retardant PVC (ZC), 1.8 mm nom.
No armour, no metallic screen
10. Scope of Application / Usage Range
ZC-YJV 0.6/1 kV 5×16 mm² is intended for fixed installation in low-voltage power distribution & transmission systems up to 1.2 kV where flame-retardant Class C is required. As a five-core cable (3L+N+PE), it is the standard choice for three-phase LV supplies with separate neutral and protective earth.
Typical applicable locations:
Three-phase distribution feeders (L1/L2/L3 + N + PE) for equipment, motors, distribution boards, and final sub-circuits in TN-S / TN-C-S systems
Indoor/outdoor distribution rooms, floor distribution cabinets, and risers in high-rise buildings, hotels, shopping malls, hospitals, schools, stations and metros (where ZC flame-retardant grade is mandated by fire code)
Cable trays, cable ducts, cable trenches & shafts in commercial / residential / public buildings
Industrial plants, warehouses, small-to-medium machinery and HVAC feeders, elevator power supplies
Direct buried routes in non-aggressive soil with low mechanical impact
Renewable / PV inverter AC output and EV charger three-phase branch circuits (polarity/earthing design required)
