RVVP 5×1.5 mm² — Flexible Shielded 5-Core Control+Signal+Power Cable — Specification

1. Overview & Ratings

RVVP 5×1.5 is a 5-core shielded control+signal+power cable rated 300/500 V. It uses pure annealed bare copper (not tinned) for both the conductor and braid, maximizing conductivity. The five 1.5 mm² cores are laid up in a circular formation and handle 5-wire control circuits, medium solenoid valves, and motor auxiliary. The braid suppresses EMI/RFI from nearby VFDs and motors. OD ≈ 12.5 mm, ≈ 135 kg/km (est.), ≈ 10–13 A. Max conductor temperature 70 °C, -15 to +70 °C. Intended for dry indoor control, signal and power circuits; for damp or outdoor duty, specify tinned copper variant.

3. Electrical Characteristics

DC resistance ≤ 13.3 Ω/km at 20 °C per GB/T 3956 Class 5 pure copper — roughly 32% lower than 1.0 mm², making it suitable for medium solenoid valves and motor auxiliary. Rated voltage 300/500 V. Estimated ampacity ≈ 10–13 A in free air at 30 °C. Insulation resistance ≥ 20 MΩ·km. Routine AC withstand test at 2000 V for 5 minutes. Typical capacitance ≈ 160 pF/m at 1 kHz. The pure copper braid provides ≈ 60–70 dB shielding at 30–1000 MHz. Voltage drop ≈ 1.60 V per 100 m at 12 A — suitable for motor auxiliary runs up to 40 m.

Insulation & Sheath Data

Electrical Parameters

Reference values: RVVP 5×1.0 at 7 A per core, 24 V DC → max load ≈ 168 W​ per core (low-power device supply). At 230 V AC → max load ≈ 1,610 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. For public or enclosed spaces, specify LSZH alternatives. The 1.0 mm Type ST jacket is oil- and abrasion-resistant for machine and panel wiring. Note: bare pure copper oxidizes in humid environments — install in dry indoor or conduit-protected locations. UV resistance is limited.

5. Installation Practice & Handling

Minimum bending radius ≥ 6×OD ≈ 75 mm for fixed installation; 12×OD ≈ 150 mm for drag-chain applications. The 12.5 mm OD and 135 kg/km make the cable robust yet flexible for routing in control panels, through conduits and along machine frames. When terminating, connect the braid shield to earth at one end (or both ends per system design) using a shield gland or drain wire. Use ferrules on the 30-strand conductors. Route the cable away from high-power motor cables by at least 300 mm. After installation, verify insulation resistance, shield continuity and 5-wire polarity before energizing.

6. Typical Service Applications

5-wire control circuits (power, signal, control, ground, shield), medium solenoid valve and actuator power, motor auxiliary circuits (brake, fan, auxiliary), PLC I/O control wiring with auxiliary power, and interconnection between control panels and field devices. The 1.5 mm² cross-section carries enough current for medium solenoid valves and motor auxiliary while the braid shield suppresses EMI from nearby VFDs and servo drives. Particularly suitable for packaging machines, textile machinery, and production lines where control, signal and power circuits share the same cable. 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 (2000 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 300/500 V rating uses a 2000 V withstand test.

8. Factory Advantages

Pure annealed copper conductor at 30×0.25 mm stranding delivers maximum conductivity with Class 5 flexibility. Lower DC resistance (13.3 vs 19.5 Ω/km) supports medium solenoid valves and motor auxiliary. 5-core circular formation combines control, signal, power, ground and shield in one cable. 0.7 mm insulation and 1.0 mm jacket provide robust dielectric and mechanical protection. Pure copper braid at ≈ 85% coverage provides low transfer impedance. Colour-coded cores prevent wiring errors. 100% routine electrical QA on every reel. Cut-to-length on coils with sealed ends. Full traceability with MTC and certification support for industrial machinery tenders.

9. Packaging, Storage & Logistics

Cut to customer-specified length on export-grade coils, with both ends heat-sealed to prevent moisture ingress. 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. The light weight makes courier and small-package shipment practical.

10. Procurement Specification

State cable designation "RVVP 5×1.5 pure copper", required length per coil, and core colour preference (e.g. red/black/white/green/yellow for 5-wire control circuits). Request the routine AC withstand test record (2000 V) and shield coverage certificate for the specific batch. Note that this is a pure copper (bare) control+signal+power variant for dry indoor use — for damp or outdoor applications, specify the tinned copper variant. 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.

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 (10–13 A vs 6–8 A), and enough current for medium solenoid valves and motor auxiliary.

Q2: Can it power medium solenoid valves? Yes — the 1.5 mm² core can carry 10–13 A, enough for medium solenoid valves and motor brake coils, while the other four cores handle control, signal, ground and shield.

Q3: How long can the motor auxiliary run be? At 24 V DC and 12 A load, voltage drop is ≈ 1.60 V per 100 m — suitable for runs up to 40 m with acceptable voltage loss.

Q4: What is the voltage rating? 300/500 V, suitable for low-voltage control, signal and power circuits.

Q5: Why pure copper instead of tinned? Bare pure copper has higher conductivity than tinned copper, ideal for control, signal and power circuits where every ohm matters.

Q6: Is it suitable for outdoor use? No — limited UV resistance and bare copper oxidize in humidity. Use indoors or in UV-protected conduits.

Q7: How do you 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 ≈ 75 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 (2000 V) + shield coverage certificate + MTC.

Q11: When should I step up to 5×2.5? For larger solenoid valves, longer runs (40+ m), or higher current loads (15+ A), step up to RVVP 5×2.5 mm².
