H05V-K (Ysf) PVC insulated single core wire rated 300/500V. Fine-stranded (Class 5) copper conductor, 0.5–10 mm². For fixed electrical installation in conduit, trunking, and panels per IEC 60364.
The H05V-K (Ysf) is a harmonized PVC-insulated single-core conductor compliant with the CENELEC HD 21 harmonized cable standard — the common technical standard that defines PVC single-core wiring cables sold across Europe and IEC-standard markets worldwide. The harmonized designation guarantees that cables from any compliant manufacturer meet the same minimum insulation thickness, conductor resistance, and voltage rating — allowing specifiers to use the designation without specifying a particular brand.
Fine-stranded Class 5 conductor — flexible enough for wiring inside control panels and enclosures where the wire must be routed around bends and dressed neatly to terminals.
| Parameter | Value |
|---|---|
| Rated Voltage | 300/500V |
| Test Voltage | 2 kV (1 min) |
| Conductor Class | Fine-stranded (Class 5) |
| Cross-Sections | 0.5–10 mm² |
| Max Conductor Temp | 70°C |
| Insulation | PVC (colour coded) |
| Standard | IEC 60227 / HD 21 |
The harmonized designation means a cable approved to HD 21 in Germany meets the same standard as one approved in France, the UK, or Australia — simplifying specification for OEM machine builders and contractors who supply equipment internationally.
IEC 60446 requires specific colours for phase (brown, black, grey), neutral (blue), and earth (green/yellow) conductors. Using colour-coded harmonized single-core wire makes conductor identification unambiguous at every point — panels, junction boxes, and equipment connections — satisfying both electrical safety standards and inspection requirements.
