RVVP 2×1.5 mm² — Flexible Shielded Control Cable — Specification 

1. Overview & Ratings

RVVP 2×1.5 is a medium-current shielded control cable rated 450/750 V, one step up from the 0.75 and 1.0 mm² variants. R = flexible tinned copper conductor, V = PVC insulation, V = PVC outer sheath, P = braided copper shield. OD ≈ 7.8 mm, ≈ 68 kg/km (est.), ≈ 12–15 A. The tinned copper braid at ≈ 85% coverage blocks EMI/RFI from nearby VFDs, servo drives and welders. The larger conductor reduces voltage drop on longer control runs, making it the preferred choice for machine tool wiring, remote PLC I/O and 24 V DC control loops. Max conductor temperature 70 °C, operating range -15 to +70 °C. Not for outdoor UV exposure or mains power.

3. Electrical Characteristics

DC resistance ≤ 13.3 Ω/km at 20 °C per GB/T 3956 — roughly 30% lower than the 1.0 mm² variant, cutting voltage drop to ≈ 1.33 V per 100 m at 10 A. Rated voltage 450/750 V. Estimated ampacity ≈ 12–15 A in free air at 30 °C. Insulation resistance ≥ 25 MΩ·km. Routine AC withstand test at 2500 V for 5 minutes. Typical capacitance ≈ 150 pF/m at 1 kHz. The braid provides ≈ 60–70 dB shielding at 30–1000 MHz. Suitable for 24 V DC and 110 V AC control loops over longer distances.

Insulation & Sheath Data

Electrical Parameters

Reference values: RVVP 2×1.5 at 10 A per core, 24 V DC → max load ≈ 240 W​ per core (control/signal use). At 230 V AC → max load ≈ 2,300 VA​ per core (not recommended for power).

4. Thermal & Flame Behaviour

Operating range -15 to +70 °C continuous. Short-circuit withstand up to 160 °C for ≤ 5 seconds. PVC insulation and jacket are flame-retardant per IEC 60332-1. The cable is halogen-containing (PVC), emitting HCl gas on burning — avoid in enclosed switchrooms where corrosive fume is a concern. For public or enclosed spaces, specify LSZH alternatives. The thicker 0.8 mm Type ST jacket offers improved oil resistance for machine tool and press applications. UV resistance is limited; install indoors or in UV-protected conduits only.

5. Installation Practice & Handling

Minimum bending radius ≥ 6×OD ≈ 47 mm for fixed installation; 12×OD ≈ 94 mm for drag-chain or moving applications. The thicker 1.5 mm² core feels stiffer than 0.75/1.0, so use proper cable management. Terminate the braid shield to earth via a shield gland or drain wire at one end (or both ends per system grounding strategy). Use appropriate ferrules on the 30-strand conductor. Route the cable at least 200 mm away from motor and VFD power cables. After installation, verify insulation resistance, shield continuity and polarity before energizing.

Mechanical & Installation Parameters

6. Typical Service Applications

Machine tool control wiring, PLC remote I/O drops, 24 V DC control loops, relay and contactor control circuits, sensor and transducer interconnection on larger machines, and low-voltage alarm circuits. The 1.5 mm² cross-section is the sweet spot for longer runs (20–50 m) where smaller cables would show noticeable voltage drop, or where auxiliary loads such as small solenoid valves demand a bit more current. Particularly valuable near variable-frequency drives, servo motors and robotic cells. Not for: mains AC power distribution, high-speed fieldbus, direct burial, or outdoor UV-exposed runs.

7. Testing & Quality Assurance Regime

Routine tests (100% production): DC resistance, AC voltage withstand (2500 V/5 min), insulation resistance, conductor construction, wall thickness, dimensional check, print legibility, mass per length, visual appearance, and packing. Type tests (per batch / material change): shield coverage, heat aging (100 °C/7 days), cold bend (-15 °C), jacket tensile, flame retardancy, and shielding effectiveness. Every coil ships with mill test certificate, ROHS and REACH declarations. The 450/750 V rating adds a higher withstand test voltage than 300/500 V cables.

8. Factory Advantages

Pure copper conductor at 30×0.25 mm stranding balances flexibility and current capacity. Thicker 0.7 mm insulation and 0.8 mm jacket match the 450/750 V rating for extra dielectric margin. Tinned copper braid at ≈ 85% coverage provides reliable EMI shielding for industrial noise environments. Lower DC resistance (13.3 Ω/km) supports longer control runs. Oil-resistant Type ST jacket for machine tool duty. 100% routine electrical QA on every reel. Cut-to-length coils with sealed ends. Lightweight ≈ 68 kg/km. Full traceability with MTC and certification support for industrial and machinery tenders.

9. Packaging, Storage & Logistics

Cut to customer-specified length on export-grade coils or wooden drums, with both ends heat-sealed. Coils wrapped in waterproof film and corrugated cardboard, labelled with product type, core count, cross-section, length, weight, production date and reel number. Standard lengths 100/200/500/1000 m. Store dry indoor, -10 to +40 °C, below 75% RH, away from direct sunlight and chemical solvents. FOB Shanghai/Nanjing/Qingdao; CIF and DAP available. Sample lead time 5–7 days; bulk production 15–25 days. Wooden drums recommended for lengths over 500 m.

10. Procurement Specification

State cable designation "RVVP 2×1.5", required length per coil/drum, and core colour preference. Request the routine AC withstand test record (2500 V) and shield coverage certificate for the specific batch. Note that the voltage rating is 450/750 V — higher than the 300/500 V of smaller cross-sections. Specify any regional certification requirements (UL 2464, CE, etc.) at order time. Payment: 30% T/T deposit, balance against B/L copy. Documents: MTC, ROHS/REACH, COO, commercial invoice, packing list. For drag-chain duty, specify RVVSP variant with enhanced flexible braid.

11. Cable Industry FAQ

Q1: Why choose 1.5 mm² over 1.0 mm²? Lower DC resistance (13.3 vs 19.5 Ω/km), higher ampacity (12–15 A vs 8–10 A), and a higher 450/750 V rating for longer control runs.

Q2: What voltage is it rated for? 450/750 V, suitable for machine tool control and 110 V AC control circuits.

Q3: How does the braid shield work? The tinned copper braid at ≈ 85% coverage diverts EMI/RFI currents to earth through the shield drain, giving ≈ 60–70 dB attenuation.

Q4: Is it suitable for drag chains? Not as standard — specify RVVSP (flexible braid) variant for continuous-flex applications.

Q5: Can it be used outdoors? No — limited UV resistance; install indoors or in UV-protected conduits.

Q6: Is it halogen-free? No — PVC is halogen-containing. Use LSZH for enclosed or public spaces.

Q7: How do I ground the shield? Connect braid to earth at one end (or both ends per system design) using a shield gland or drain wire.

Q8: What is the bending radius? ≥ 6×OD ≈ 47 mm for fixed; 12× for moving applications.

Q9: What is the temperature range? -15 to +70 °C continuous.

Q10: What proof ships? Routine AC test record (2500 V) + shield coverage certificate + MTC.

Q11: Can it carry 24 V DC signals? Yes — 1.5 mm² is well suited for 24 V DC control loops over longer distances with minimal voltage drop.
