H05VV-F and H07VV-F are types of flexible electrical cables commonly used in Europe that conform to Harmonized (HAR) standards. Below is a breakdown of their specifications:
1. H05VV-F
Voltage Rating: 300/500V (for light-duty applications)
Conductor: Copper (stranded for flexibility)
Insulation: PVC (Polyvinyl Chloride)
Sheath: PVC (flexible and abrasion-resistant)
Temperature Range: -5°C to +70°C (remains flexible at low temperatures)
Applications:
Household appliances (irons, lamps, small electronics)
Extension cords
Light-duty power connections
2. H07VV-F
Voltage Rating: 450/750V (for heavier-duty applications)
Conductor: Copper (stranded)
Insulation: PVC
Sheath: PVC (more robust than H05VV-F)
Temperature Range: -5°C to +70°C
Applications:
Industrial equipment
Power tools
Fixed installations (where flexibility is needed)
Heavy-duty extension cords
Key Differences:
| Feature | H05VV-F | H07VV-F |
|---|---|---|
| Voltage | 300/500V | 450/750V |
| Use Case | Light-duty | Heavy-duty |
| Thickness | Slightly thinner | Slightly thicker |
Standards Compliance:
Both cables comply with Harmonized (HAR) standards (EN 50525 series).
"H" = Harmonized European cable.
"05" / "07" = Voltage rating.
"VV" = PVC insulation + PVC sheath.
"F" = Fine-stranded flexible conductor.
When to Use Which?
H05VV-F: Suitable for low-power devices and short extensions.
H07VV-F: Recommended for higher-power tools and fixed installations requiring flexibility.
