Flexible RV H07V-K Power Wire with Copper Conductor and PVC Insulation for Enhanced Mobility

How to Select the Right Flexible RV / H07V-K Power Wire

1. Voltage Rating

Confirm the system voltage does not exceed the cable rating:

• H07V-K: 450/750V (U₀/U), suitable for most low-voltage control and power circuits.

• RV: Typically 450/750V or 300/500V depending on the standard and manufacturer.
  For three-phase 400V systems, 450/750V is the standard choice. For lower-voltage control circuits, 300/500V may be sufficient.

2. Conductor Flexibility and Stranding

• Class 5 (fine strand): Highest flexibility, best for mobile applications, tight bends, and vibration-prone equipment.

• Class 2 (stranded): Moderate flexibility, suitable for fixed installations with occasional bending.

• Solid (Class 1): Not recommended for applications requiring mobility.
  For enhanced mobility, select Class 5 conductor according to IEC 60228.

3. Cross-Sectional Area

Select the conductor size based on:

• Continuous load current

• Permissible voltage drop

• Ambient temperature and grouping

• Short-circuit withstand
  Typical range: 0.5 mm² to 240 mm². For control panels, 0.5–6 mm² is common. For power connections, 10–240 mm² may be required.

4. Insulation Material and Temperature

• PVC insulation: Standard, rated 70°C continuous. Suitable for most indoor applications.

• Heat-resistant PVC: Available for higher temperatures if required.

• Flame-retardant PVC: For installations requiring IEC 60332-1 or project-specific fire performance.
  Confirm the maximum conductor temperature and ambient conditions.

5. Installation Environment

• Indoor dry locations: Standard PVC is adequate.

• Humid or wet areas: Confirm suitability or consider alternative insulation.

• High-temperature areas: Verify temperature rating against ambient and equipment heat.

• Panel and cabinet wiring: Flexible wire simplifies routing and reduces stress on terminals.

• Mobile equipment: Select high strand count and appropriate bending radius.

6. Bending Radius

• Fixed installation: Typically 4 × outer diameter.

• Flexible/mobile installation: Typically 6 × outer diameter or as specified by the manufacturer.
  For repeated flexing, follow the recommended minimum bending radius to avoid conductor fatigue.

7. Color Coding

Select colors for phase, neutral, and protective earth:

• Phase: Black, brown, grey, or other colors.

• Neutral: Blue.

• Protective earth: Green/yellow.

• Other: Red, white, orange, etc., for control or signal wiring.
  Confirm color requirements against local wiring codes.

8. Standards and Approvals

• H07V-K: EN 50525-2-31, IEC 60227, VDE 0281.

• RV: GB/T 5023, JB/T 8734.

• Flame retardance: IEC 60332-1.

• RoHS / REACH: Confirm compliance if required for the destination market.
  Request test reports or certificates of conformity as needed.

9. Packaging and Length

• Coils: 100 m, 200 m, or custom.

• Drums: For larger cross-sections or long lengths.

• Cut lengths: Pre-cut with terminals or ferrules if required.
  Confirm packaging to protect insulation during transport and storage.

Technical Specifications

Note: Specifications vary by manufacturer and standard. Confirm actual dimensions, temperature rating, and approvals before ordering.

Typical Applications

• Switchgear and control panel internal wiring

• Distribution boards and meter boxes

• Electrical equipment and appliance connections

• Portable tools and temporary power leads

• Lighting circuits and signal wiring

• Automation and instrumentation panels

• Maintenance and repair wiring where flexibility is required
