Cable Designation Breakdown for H07RN-F 3G1,5

When selecting a cable like H07RN-F 3G1,5, there are several options available for each part of the designation. Below is a breakdown of what each specification means and the alternatives you might encounter.

1. Cable Type (H)

• H: Harmonized, meeting European standards.
• A: Higher voltage cables.
• X: Special-purpose cables.

2. Voltage Rating (07)

• 03: 300/500V (light-duty applications).
• 05: 300/500V (domestic light applications).
• 07: 450/750V (medium to heavy-duty industrial use).
• 1: 1,000V (heavy-duty equipment).

3. Insulation Type (R)

• R: Rubber insulation (flexible and temperature-resistant).
• V: PVC insulation (chemical resistant).
• E: EPR (Ethylene Propylene Rubber) for higher temperatures.
• K: Halogen-free insulation for safety.

4. Sheathing Material (N)

• N: Neoprene (oil, chemical, and UV resistant).
• T: Textile-braided for enhanced flexibility.
• Z: Halogen-free outer sheath (fire safety).
• Y: PVC sheath (economical but less resistant to environmental factors).

5. Flexibility (F)

• F: Flexible, suitable for mobile or portable equipment.
• H: Hard-use, more rigid for stationary use.
• K: Extra-flexible for highly mobile tools.

6. Number of Conductors (3G)

• 3G: 3 conductors, including a green/yellow ground wire.
  • Variations:
  • 2G: 2 conductors with a ground wire.
  • 4G: 4 conductors with a ground wire.
  • 3x: 3 conductors without a ground wire.

7. Cross-sectional Area (1,5 mm²)

• 0.75 mm²: Very light-duty.
• 1.0 mm²: Low-power applications.
• 1.5 mm²: Moderate power loads (portable tools).
• 2.5 mm²: Higher power loads (industrial machinery).

Other Considerations

• Armoring: Options like steel or aluminum armoring (e.g., SWA) for additional protection.
• Temperature Rating: Ensure the cable is rated for the expected temperature range.
• Fire and Smoke Protection: Use LSZH (Low Smoke Zero Halogen) for areas requiring high fire safety.

By understanding these designations, you can select the best cable suited to your specific electrical, safety, and environmental needs.
