Construction Description
| Construction Description — RVVP 2×4.0 mm² heavy shielded control cable | |||
| Layer-by-layer heavy shielded control cable: 2×large flexible Cu / PVC insulation / copper braid shield / PVC sheath · 300/500 V · 70 °C · ≈ 10.0 mm | |||
| 1. Product Identity & Ratings | |||
| RVVP 2×4.0 is a heavy shielded flexible PVC control cable rated 300/500 V, 70 °C continuous. Built per GB/T 9330 / IEC 60227. Two 4.0 mm² large flexible copper conductors enclosed in a copper wire braid shield (≥ 80% coverage) and PVC outer sheath. Designed for motor power and heavy control circuits. Finished OD ≈ 10.0 mm, mass ≈ 190 kg/km, 100 m coils. | |||
| 2. Two Large Flexible Copper Conductors | |||
| Two 4.0 mm² fine-stranded annealed copper conductors (Class 5, ~56×0.30 mm). DC resistance ≤ 4.61 Ω/km at 20 °C. The large flexible construction handles up to ~23 A for motor power and drive interconnection. | |||
| 3. Heavy Copper Braid Shield | |||
| Tinned copper wire braid woven over the insulated cores with ≥ 80% coverage. The heavier braid shield blocks EMI/RFI from VFDs, motors, and power cables — critical when carrying both power and signal in noisy industrial environments. | |||
| 4. PVC Outer Sheath | |||
| PVC outer sheath ≈ 1.4 mm thick, dark brown. Provides heavy-duty mechanical protection. The flexible sheath bends for equipment interconnection but requires a generous 6×OD bend radius. | |||
| 5. Site Handling & Operational Notes | |||
| • Bend radius 6×OD (≈ 60 mm). • Use crimp lugs and heavy terminal blocks. • Ground shield at both ends. • At 190 kg/km, heavy. • Indoor use. • Heavy control / power (≈ 23 A max). |
8. Standards & Conformity. GB/T 9330 (plastic insulated control cables); IEC 60227 (international); GB/T 3956 (Class 5 flexible conductors). Rated 300/500 V.
9. Packaging, Storage & Logistics. 100 m per coil, plastic wrapped. Continuous marking: RVVP, 2×4.0, 300/500V, GB/T 9330. Store dry, indoor.
10. Procurement Specification. State "RVVP 2×4.0" + length. Specify shield coverage requirement (≥ 80%). Confirm against factory test certificate.
11. Cable Industry FAQ.
- Q1: What is the difference between RVVP 2×4.0 and RVVP 2×2.5? The 4.0 mm² version has 60% more copper cross-section, is 25% thicker (10.0 vs 8.0 mm), 46% heavier (190 vs 130 kg/km), and carries 44% more current (23 vs 16 A). It is for motor power; the 2.5 mm² version is for general control.
- Q2: Why choose 4.0 mm²? When you need to carry up to ~23 A while maintaining EMI shielding — e.g., powering small motors, solenoids, or drives — 4.0 mm² provides the current capacity. The 2.5 mm² version is limited to ~16 A.
- Q3: Can it power a small motor? Yes — up to ~23 A at 300/500 V is enough for fractional-horsepower motors and drive inputs. The shield prevents VFD noise from radiating back into the control circuit.
- Q4: What connectors are used? Heavy crimp lugs, ferrules, or terminal blocks rated for 4 mm² conductors. The 2.5 mm conductor diameter requires larger lugs than the 2.0 mm in RVVP 2×2.5.
- Q5: Is the shield heavier? Yes — the braid is thicker (0.6 vs 0.5 mm) and shield resistance is lower (≤ 15 vs ≤ 20 Ω/km) because it wraps larger cores. Coverage remains ≥ 80%.
- Q6: Can it be used as a power cable? It can carry up to 23 A at 300/500 V, but it is not a power cable per se. For true power distribution, use RVV or YJV. RVVP 2×4.0 is for shielded power/control hybrid runs.
- Q7: What is the bending radius? 6×OD ≈ 60 mm — stiffer than the 48 mm of RVVP 2×2.5 due to the larger conductors.
- Q8: Can it be used outdoors? No — PVC sheath is not UV-resistant. For outdoor use, use outdoor-rated cable.
- Q9: How does it compare to RVVP 2×6.0? The 6.0 mm² version carries ~30 A and is for heavier motor power. The 4.0 mm² version carries 23 A and is the sweet spot for small drives and heavy control. If you need more than 23 A, step up to 6.0 mm².
- Q10: Should the shield be grounded at one or both ends? For VFD and high-frequency noise, ground at both ends. For low-frequency signals, one end only. With 4.0 mm² power/control hybrid, both ends is typical.
- Q11: What is the standard? GB/T 9330 / IEC 60227 for plastic insulated control cables, rated 300/500 V.
