Shielding Performance

5. Installation Practice & Handling. Use shielded connectors. Ground shield at one end (low-frequency signals) or both ends (high-frequency). Do not run shielded and unshielded cables in the same tray. At 130 kg/km, very light. Indoor use only.

Mechanical & Installation Parameters

6. Typical Service Applications. Instrument signal transmission, sensor wiring, PLC control circuits, audio interconnection, data acquisition, alarm systems — anywhere low-level signals must be protected from electromagnetic interference.

7. Testing & QA Regime. Routine: conductor DC resistance, 2.0 kV AC withstand, insulation resistance, shield coverage check, dimensional check. Type: heating test, bending test, flame retardancy, mutual capacitance measurement.

11. Cable Industry FAQ.

• Q1: What does "RVVP" mean? R = flexible (soft); V = PVC insulation; V = PVC sheath; P = shielded (copper braid). It is a shielded flexible control cable.
• Q2: What is the difference between RVVP and RVV? RVV is unshielded. RVVP adds a copper wire braid shield over the insulated cores. Use RVVP when nearby power cables or motors could induce noise into signal circuits.
• Q3: Why use a shielded cable? In industrial environments, power cables, VFDs, and motors radiate electromagnetic noise. The copper braid shield absorbs this noise and prevents it from corrupting low-level sensor or control signals.
• Q4: Should the shield be grounded at one end or both ends? For low-frequency signals (< 1 MHz), ground at one end only to avoid ground loops. For high-frequency signals (> 1 MHz), ground at both ends for better high-frequency shielding.
• Q5: What is the difference between this and YJV22 power cable? YJV22 is a large armored power cable (62 mm, 8200 kg/km, 370 A) for high-power distribution. RVVP is a small shielded control cable (8 mm, 130 kg/km, 16 A) for low-level signal circuits. They serve completely different purposes.
• Q6: Can RVVP carry power? It can carry limited power (≈ 16 A), but that is not its purpose. Use RVVP for signal and control. For power, use RVV or YJV.
• Q7: What is the shield coverage? ≥ 80% copper braid coverage. Higher coverage provides better shielding but reduces flexibility.
• Q8: Can I use RVVP outdoors? No — PVC sheath is not UV-resistant. For outdoor use, use outdoor-rated cable.
• Q9: What connectors should I use? Use shielded connectors (D-sub, M12, etc.) that maintain the shield continuity through the connector. Do not break the shield at the connector.
• Q10: Can I run RVVP parallel to power cables? Avoid it if possible. If unavoidable, maintain at least 200 mm separation and cross at 90°. The shield helps but does not eliminate all interference.
• Q11: What is the bending radius? 6×OD ≈ 48 mm — flexible enough for panel wiring and equipment interconnection.
