Low Voltage 2 Cores Cable 2 X 10mm2 Stranded Copper Fire Resistant PVC Insulated Sheathed

Low Voltage Power Cable 0.6/1kv YJV-2*10mm² Stranded Copper XLPE Insulation Fire-Resistant PVC Outer Sheath

Technical Datasheet — ZC-YJV 0.6/1 kV 2×10 mm²

1. Cable Designation & Meaning

Compared with plain YJV 2×10, the only difference is the ZC prefix: flame-retardant PVC sheath + flame-retardant filler/binder, passing Class C bunched flame test. Dimensions, conductor, insulation thickness and electrical values are identical.

2. Applicable Standards

• GB/T 12706.1-2020​ (equiv. IEC 60502-1) — Extruded insulation power cables ≤ 1 kV
• GB/T 3956 / IEC 60228​ — Conductors (Class 2)
• GB/T 19666-2019​ — Flame retardant & fire resistant cables (ZC = Class C)
• GB/T 18380.3​ — Bunched flame propagation test, Class C (sample non-metal volume 1.5 L/m, flame 20 min, char ≤ 2.5 m above burner)

3. Product Components / Construction (inside → outside)

1. Conductor (×2)​ — Bare annealed copper, Class 2 stranded circular, 7×∅1.35 mm​ (typical); Class 1 solid permitted for 10 mm²
2. Conductor screen​ — Not required for 0.6/1 kV; omitted
3. Insulation (×2)​ — XLPE compound, extruded (red/black/blue/brown etc.)
4. Insulation thickness (nominal)​ — 0.7 mm​ (GB/T 12706.1, 10/16 mm² class)
5. Filler​ — Flame-retardant non-hygroscopic PP/PE filler​ (ZC grade, replaces plain filler)
6. Binder​ — Flame-retardant glass-fibre tape / halogen-free flame-retardant tape​ (ZC grade)
7. Outer sheath​ — Flame-retardant PVC​ compound (ZC grade)
8. Sheath thickness (nominal)​ — 1.8 mm​ (multi-core rule)
9. Sheath colour​ — Black (standard); other colours available
10. Armour​ — None
11. Metallic screen​ — None

10. 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

11. Packing

• Drum / coil:​ Steel-wooden drum or coil, 100–500 m typical.
