Bottom line: TFR-CV (Korea) is closest in performance and construction to Chinese ZR-YJV (ZC-YJV) 0.6/1kV flame-retardant power cable — not BVV.
TFR = Tray Flame Retardant; CV = Cu / XLPE / PVC sheathed cable. ZR-YJV = copper conductor, XLPE insulation, flame-retardant PVC sheath, 0.6/1kV power cable, to GB/T 12706.1.
Both are 0.6/1kV, XLPE insulated, flame-retardant PVC sheathed low-voltage power cables with Class 2 compact stranded copper conductors, and their applications overlap heavily (tray laying, plant distribution, PV inverter AC side). But the flame-retardant test systems differ, so they cannot be treated as identical in quotes.
Specification Comparison
| Item | Korean TFR-CV | Chinese ZR-YJV (ZC-YJV) |
|---|---|---|
| Rated voltage | 0.6/1kV AC | 0.6/1kV AC |
| Conductor | Class 2 compact stranded hard copper | Class 2 compact stranded hard copper |
| Insulation | XLPE, 90℃ continuous | XLPE, 90℃ continuous |
| Sheath | FR-PVC (tray flame retardant TFR) | FR-PVC (GB A/B/C flame retardant classes) |
| Standard | KS C IEC 60502-1 | GB/T 12706.1 (equivalent to IEC 60502-1) |
| Application | Tray laying, plant / PV inverter AC side | Tray, indoor distribution, PV inverter AC output |
Key Differences (export focus — not directly interchangeable)
1. Different flame-retardant test systems
TFR is Korea's dedicated tray bundled flame-retardant test; Chinese ZR/ZC follows GB/T 18380 bundled flame retardancy. Material performance is close, but the test standards differ. For Korean project acceptance, domestic ZR-YJV cannot directly replace TFR-CV unless it first passes the Korean TFR flame test and obtains KC certification.
2. Printing & color rules
Korea's KEC electrical code has separate requirements for conductor colors and markings (e.g. single-core black, multi-core black/white/red/green), differing from Chinese GB practice. Export to Korea must adjust printing and colors to KEC.
3. Plain YJV is not flame-retardant
Plain YJV ≠ TFR-CV — you must specify ZR-YJV / ZC-YJV (flame-retardant type). Plain YJV sheath is not mandatorily flame-retardant and fails tray flame requirements.
❌ Models to exclude
- BVV: PVC insulated, 70℃, 300/500V — far from TFR-CV, unsuitable as a substitute (see TFR-CV 6sq vs BVV 6sq).
- VV: PVC insulated and sheathed, not XLPE — one tier lower in current rating and temperature tolerance.
Sourcing & Quotation Tips
- For Korean projects, quote TFR-CV + KS(KC) certification first. If the buyer accepts a domestic equivalent, clarify the feasibility and lead time of "ZR-YJV + Korean TFR flame test + KC".
- Printing example:
TFR-CV 0.6/1kV 1×6mm² KS C IEC 60502-1 Cu XLPE FR-PVC. - Never substitute with plain YJV or BVV — acceptance risk is very high.
FAQ
Q1: Which Chinese model is closest to TFR-CV? A: ZR-YJV (or ZC-YJV) 0.6/1kV copper XLPE insulated FR-PVC sheathed power cable — matching voltage, insulation, conductor and application. BVV is not.
Q2: Why is TFR-CV not the same as BVV? A: BVV is PVC insulated, 70℃ continuous, 300/500V building wire, whereas TFR-CV is XLPE insulated, 90℃, 0.6/1kV power cable — insulation, temperature, voltage and flame rating all differ.
Q3: Can Chinese ZR-YJV directly replace TFR-CV for export? A: Material is close, but not directly. Korean acceptance requires the TFR tray flame system and KC certification; ZR-YJV must pass the Korean TFR flame test and obtain KC, otherwise EPC projects cannot be accepted.
Q4: Can plain YJV be used as TFR-CV? A: No. Plain YJV sheath is not mandatorily flame-retardant and fails tray flame requirements; you must use the ZR/YJV flame-retardant type.
Q5: What is the difference between VV and TFR-CV? A: VV is PVC insulated and sheathed, not XLPE cross-linked polyethylene, so its current rating and temperature tolerance are one tier lower — not equivalent.
