Product Overview

H05V-U / H07V-U PVC Insulated Single Core Wire is a solid bare copper conductor PVC insulated installation wire manufactured to DIN VDE 0281-3 and DIN EN 60228. The harmonised European designation encodes the key technical parameters: H = harmonised type (CENELEC), 05 = 300/500V or 07 = 450/750V voltage class, V = PVC insulation, -U = single-core solid conductor. Stripping the designation reveals the complete specification: H05V-U is the 300/500V solid wire for signal and control circuits (0.5-1.0mm²), while H07V-U is the 450/750V solid wire for higher-voltage fixed installations (1.5-10mm²). Both variants share the same PVC insulation compound, 70°C continuous rating, and EN 60332-1-2 flame retardancy certification — the entire range is interchangeable in construction and only differentiated by operating voltage and cross-section.

The H05V-U/H07V-U wire occupies a specific niche in European electrical practice: it is the solid-core counterpart to the stranded flexible NYAF and the green/yellow earth wire, designed for protected fixed installations where the wire, once terminated, remains stationary for its service life. Solid copper's advantages over stranded for this application are threefold: no strand separation during terminal tightening (a common failure mode with fine-strand wire under screw terminals), lower cost due to simpler manufacturing, and a 4×D bending radius — surprisingly tighter than Class 2 stranded house wire (15×D) because the solid conductor's single rigid core holds its bend shape without spring-back. However, the application scope is limited by VDE 0281-3 to signal circuits and control circuits only when installed under plaster or in pipes — this wire is not approved for main power distribution circuits where current-carrying capacity demands larger cross-sections than the 10mm² maximum in this range.

For electrical wholesalers, H05V-U/H07V-U represents the entry-level solid single-core product line — the most affordable per-metre wire in the building wire category. Packaged in standardised 100m rolls with export wooden case and pallet, the small overall diameters (2.1-5.7mm) and lightweight construction (9-115 kg/km) enable dense container loading — a single 20ft container can hold over 10,000 rolls of 1.5mm² wire, making this product line viable for high-volume export to markets where European harmonised standards are referenced in local wiring codes.

H05V-U H07V-U Wire Cross Section — Left: Solid copper conductor with PVC insulation, Right: Stranded copper conductor with PVC insulation

Left Diagram — Solid Conductor (H05V-U/H07V-U):
Copper conductor — Single solid copper core, no stranding — the defining feature of the -U (solid) designation
PVC insulation — Blue outer layer, uniform wall thickness per cross-section (0.6-1.0mm)

Right Diagram — Stranded Conductor (Reference):
Copper conductor — 7-strand copper bundle — for comparison only; H05V-U/H07V-U uses solid conductor
PVC insulation — Same blue PVC compound and thickness as solid variant

Two Voltage Variants

H05V-U: 300/500V, 0.5-1.0mm² for signal & control circuits. H07V-U: 450/750V, 1.5-10mm² for higher-voltage fixed installations.

4×D Tight Bending

Solid wire bends once and holds shape — no spring-back. 4×D minimum bending radius enables neat right-angle routing in tight terminal boxes.

100m Standard Export Roll

Wooden case + pallet. Ultra-lightweight (9-115 kg/km) — up to 10,000+ rolls per 20ft container for export wholesalers.

6

Signal & Control Only

Per VDE 0281-3: not approved for main power circuits under plaster. Use NYM multi-core cable or larger H07V-K stranded wire for power applications.

Applicable Standards

StandardScope
DIN VDE 0281-3German national standard for PVC insulated cables up to 450/750V — Part 3: single core non-sheathed cables for fixed wiring. Primary standard for H05V-U and H07V-U.
DIN EN 60228Conductor standard for insulated cables. Class 1 (solid) copper conductors — the single solid core unique to the -U designation.
EN 60332-1-2Single cable vertical flame test with 1kW pre-mixed flame. Mandatory for all CENELEC harmonised installation wires.
ⓘ H05V-U/H07V-U compared to other building wires: H05V-U/H07V-U is the solid-core CENELEC harmonised wire. Use it for protected fixed installations where the wire stays stationary. For flexible routing in control panels, specify NYAF (Class 5 stranded, same voltage class, 4-6×D bending). For main power circuits under plaster, specify NYM multi-core cable (300/500V, PVC/PVC, damp-rated). For earth/ground connections, specify H07V-U green/yellow (same construction, PE-only colour). The stranded diagram in the cross-section image is shown as a construction reference only — H05V-U/H07V-U uses exclusively solid conductor per the -U suffix.

H05V-U vs H07V-U: The voltage boundary: The dividing line between 300/500V (H05) and 450/750V (H07) harmonised wire families falls at 1.0mm² → 1.5mm². H05V-U at 0.5-1.0mm² is exclusively for signal circuits, control circuits, and protected fixed wiring inside appliances and lighting fittings — these tiny conductors (OD as small as 2.1mm) would be unsafe for power distribution where fault currents demand larger cross-sections. Above 1.0mm², the wire jumps to H07V-U 450/750V rating which covers all standard single-phase and three-phase building circuit voltages. The H05V-U designation for ≤1.0mm² is standard across the harmonised European system — H05V-K (flexible) and H05V2-U (90°C PVC) follow the same voltage boundary.
