Electrical Parameters

Reference values: 4.0 mm² Cu at 24 A, 3-phase 400 V (3P+1N+PE) → max balanced load ≈ 16.6 kVA. Voltage drop at 24 A ≈ 5.9 V/km per core (≈0.26% per 10 m at 400 V).

4. Thermal & Flame Behaviour. 70 °C continuous, 160 °C short-circuit (≤ 5 s); -15~+70 °C ambient, ≥ -15 °C laying; flame-retardant to GB/T 18380 / IEC 60332-1 (self-extinguishing). PVC contains halogen → RVVSP (LSZH) for halogen-free.

Fire Performance (RVV — Standard)

5. Installation Practice & Handling. Bend ≥ 6 × OD ≈ 80 mm fixed, ≥ 10 × OD ≈ 135 mm flexed; always use ferrules (cord end terminals) for stranded conductors; lay in trunking, tray, conduit, or indoor sheltered locations. Core colours: R/Y/B = L1/L2/L3, light blue = N, green = PE.

Mechanical & Installation Parameters

6. Typical Service Applications. 3-phase equipment power, motor connections, machine tool supply, distribution panel to machinery, industrial automation, pump/compressor power — indoor or sheltered outdoor.

7. Testing & QA Regime. Routine: conductor DC resistance ≤ 4.61 Ω/km, 2.0 kV AC / 5 min withstand, dimensional check (inner insulation ≥ 0.7 mm, sheath ≥ 1.5 mm, OD ≈ 13.5 mm). Type: heat ageing at 100 °C / 168 h, cold bend at -15 °C, heat shock at 150 °C, insulation resistance, flame retardancy per GB/T 18380.

11. Cable Industry FAQ.

• Q1: What is the difference between RVV-5×4.0 and ZC-YJV 4×50? RVV-5×4.0 is a 5-core flexible PVC cable (300/500 V, 70 °C, Class 5 strands, 25 A, 350 kg/km) for equipment power. ZC-YJV 4×50 is a 4-core XLPE power cable (0.6/1 kV, 90 °C, Class 2 compacted, 175 A, 2380 kg/km) for distribution trunking. Different voltage, temperature, current, and conductor class.
• Q2: Why 5 cores? A 5-core cable provides 3 phases (L1/L2/L3) + neutral (N) + protective earth (PE) in one sheath — everything needed for a 3-phase equipment connection. No need to run separate earth wire.
• Q3: When do I need 5 cores vs 4 cores? Use 5-core when the load requires a neutral (e.g. 3-phase equipment with 230 V control circuits). Use 4-core (3P+PE) for 3-phase loads that don't need neutral (e.g. motors).
• Q4: Can RVV carry 3-phase motor current? Yes — RVV-5×4.0 at 25 A per core can drive small 3-phase motors up to about 11 kW (at 400 V). For larger motors, use YJV (XLPE, higher ampacity).
• Q5: What is the difference between RVV and RVVP? RVVP adds a copper wire braid screen over the cores. Use RVVP near EMI sources (VFDs, inverters). RVV is unshielded.
• Q6: Why use Class 5 flexible strands instead of Class 2 compacted? Class 5 (26×0.45) is flexible — easy to route inside equipment and between panels. Class 2 (7×3.0) is rigid — for fixed underground distribution. RVV is for equipment connections; YJV is for fixed distribution.
• Q7: What is the minimum bending radius? 6 × OD for fixed (≈ 80 mm), 10 × OD for flexing (≈ 135 mm). Much smaller than ZC-YJV 4×50 (15×OD ≈ 430 mm) because RVV is a small flexible cable.
• Q8: Can RVV-5×4.0 be used outdoors? Only sheltered. For outdoor or burial, use YJV or YJV22 (armored). RVV's PVC sheath is not UV-stable.
• Q9: What size ferrules do I use? 4.0 mm² cord end terminals (ferrules), crimped with a ferrule crimper. Do not use bare stranded wire without ferrules.
• Q10: What is the difference between RVV and RVVB? RVV is round (circular cross-section). RVVB is flat (oblong, 2 cores side by side). For 5-core, RVV is always round.
• Q11: How do I choose between RVV and YJV for equipment? If the equipment is rated 300/500 V or less and the connection is short/flexible, use RVV. If the equipment is rated 0.6/1 kV and the run is long/high-current, use YJV. For 3-phase small equipment, RVV-5×4.0 is the standard choice.
