Technical Datasheet — ZC-YJV 3×16 mm² Low Voltage Power Cable (Three-Core, Copper Conductor, XLPE Insulated, PVC Sheathed, Flame Retardant C)

Standard Compliance Note: ZC-YJV is a flame-retardant C, cross-linked polyethylene (XLPE) insulated, PVC sheathed power cable. Parameters below are based on GB/T 12706.1-2020 / IEC 60502-1 and typical Chinese manufacturer technical data.

✅ This is a STANDARD SIZE.​ 3×16 mm² three-core power cable is within the standard production range (1.5 mm² to 400 mm² per GB/T 12706.1-2020). Widely stocked​ by Chinese manufacturers and commonly specified for small three-phase motors, distribution boards, and industrial equipment circuits.

⚠️ Note:​ This cable is UNSHIELDED​ (no copper tape/wire screen). The designation "YJV" indicates no shield layer. For a shielded equivalent, the correct model is YJVP​ (copper tape screen).

⚠️ Note:​ This is a THREE-CORE​ cable (3×16 mm² = 3 cores of 16 mm² each). It is typically used for three-phase 3-wire systems​ (3L, no neutral). For three-phase systems requiring a neutral, use 4-core​ (3L+N) or 5-core​ (3L+N+E) versions.

Cable Designation & Meaning

Construction: Three Class 2 stranded copper conductors, XLPE insulation, PVC outer sheath (no armour, no shield, circular formation).

Applicable Standards

• Maximum pulling tension (copper conductor only):​ 50 N/mm² × 16 mm² = 800 N​
• PVC sheath pulling limit:​ significantly lower — avoid direct sheath grip; use conductor pulling eye
• Direct burial:​ Allowed in non-aggressive soil; recommended sand bed + warning tape, depth ≥ 0.7 m, conduit under roads

10. Scope of Application / Usage Range

The ZC-YJV 0.6/1 kV 1×16 mm²​ cable is intended for fixed installation​ in low-voltage power distribution & transmission systems up to 1.2 kV system voltage, where basic flame-retardant (Class C)​ performance is required but fire-survival (fire-resistant)​ function is not mandated.

Typical applicable locations:

• Indoor power distribution rooms, switchboards, distribution boxes, and final sub-circuits
• Cable trays, cable ducts, cable trenches & shafts in residential, commercial and public buildings
• Lighting branch circuits and small-to-medium power equipment feeders​ (16 mm² is a standard size for lighting/utility circuits)
• Fixed wiring in industrial plants, warehouses, and machinery feeders
• Direct buried routes in non-aggressive soil with low mechanical impact
• Street lighting, small PV/combiner and EV charger branch circuits (DC side requires polarity check)
• High-rise buildings, metro/station auxiliary power, general civil projects requiring ZC flame-retardant grade​

Not suitable for:

• Heavy tensile / armour-protected routes → use YJV22 / ZC-YJV22
• Fire-survival emergency circuits → use NH-ZC-YJV
• Highly corrosive / hydrocarbon-rich environments without extra barrier
• Magnetic conduit AC single-core runs​ (eddy-current risk)
• Long high-current feeders where voltage drop / 105 A limit governs (upsize to 25 mm²+)

11. Packing

• Drum:​ Steel-wooden drum; common length 100–1000 m per drum (16 mm² flexible, long continuous lengths typical)
• HS code (China):​ 8544 4921 (LV power cable, PVC sheath)

Key engineering notes for 16 mm²

1. Insulation is only 0.7 mm​ — the same as 1.5 mm². This is correct per GB/T 12706.1 (the 10/16 mm² class). Do not apply the 1.2/1.6 mm values from 120/185 mm².
2. Sheath is 1.4 mm​ (not 1.5/1.7 mm) — single-core 1.5–35 mm² share this value .
3. Conductor is 7×1.70 mm​ for stranded (Class 2); solid Class 1 is also permitted for 16 mm² ≤ 35 mm² .
4. Design current: ≈ 100 A (air) / ≈ 115–125 A (buried)​ — always apply correction for grouping, ambient temperature, and conduit fill; for a 30 kW motor (≈54 A) at 200 m, 16 mm² gives voltage drop ≈ 2.4 V (well within 19 V limit) .
5. ZC ≠ NH:​ ZC is flame-retardant only, not fire-survival. For emergency/life-safety circuits, use NH-ZC-YJV.
