6. Electrical Parameters

7. Temperature Characteristics

• Max. conductor operating temp. (continuous):​ 90 °C​
• Max. short-circuit temp. (≤5 s):​ 250 °C​
• 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

• 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)
