H07V-U Single Core Cable – Rigid PVC-Insulated Wire for Fixed Installations
The H07V-U is a rigid (solid/single-wire) PVC-insulated single-core cable manufactured to **DIN EN 50525-2-31** (VDE 0285-525-2-31). With a rated voltage of 450/750 V, it is designed for fixed wiring in buildings, switchgear, distribution boards, and installation conduits. As a trusted supplier for professional electricians, electrical service companies, construction & renovation firms, van conversion specialists, research facilities, and B2B buyers, we offer this reliable installation wire in various cross-sections and colors (e.g., green-yellow for protective earth, blue, black, red) – always with current CPR class Eca (low flame spread).
Technical Specifications of H07V-U Cable
Overview of key parameters for the most common cross-sections (based on current standards and manufacturer data as of 2026):
| Parameter | 1.5 mm² | 2.5 mm² | 4 mm² |
|---|---|---|---|
| Conductor Material | Bare Copper (Cu) | Bare Copper (Cu) | Bare Copper (Cu) |
| Conductor Class | Class 1 (solid) | Class 1 (solid) | Class 1 (solid) |
| Insulation | PVC TI1 | PVC TI1 | PVC TI1 |
| Outer Diameter (approx.) | 2.8–3.0 mm | 3.4–3.6 mm | 4.2–4.5 mm |
| Insulation Thickness (nominal) | 0.7 mm | 0.8 mm | 0.8 mm |
| Max. Conductor Resistance (Ω/km at 20 °C) | 12.1 | 7.41 | 4.61 |
| Current Carrying Capacity (Installation Method C – in air, 30 °C, 2 loaded conductors) | approx. 24 A | approx. 32 A | approx. 42 A |
| Min. Bending Radius (fixed installation) | 4 × Ø | 4 × Ø | 4 × Ø |
| Max. Conductor Temperature | +70 °C | +70 °C | +70 °C |
| Permitted Ambient Temperature (fixed) | -5 °C to +70 °C | -5 °C to +70 °C | -5 °C to +70 °C |
| CPR Fire Behavior Class | Eca (EN 50575) | Eca (EN 50575) | Eca (EN 50575) |
| Flame Retardancy | IEC 60332-1-2 | IEC 60332-1-2 | IEC 60332-1-2 |
Typical Applications of H07V-U – Perfect for Professionals & B2B Projects
The rigid H07V-U is suitable exclusively for **fixed installations** in dry and damp indoor environments – ideal in conduits, trunking, under plaster, or in control cabinets. Compared to the flexible H07V-K (stranded), it is easier to install in straight runs and more cost-effective for long, linear sections.
Building Electrical Installations (New Builds & Renovations)
Used as phase, neutral, or protective conductor (green-yellow) in socket outlets, lighting, and switching circuits. Perfect for electrical contractors and renovation companies when installed in pipes or embedded in concrete.
Switchgear and Distribution Board Construction
Internal wiring in control panels and main distributors. The solid construction allows precise, kink-resistant routing and high mechanical stability.
Van Conversion & Campervan Builds
For fixed onboard electrics (lighting, 230 V sockets, chargers). In confined vehicle spaces, its flame-retardant properties add extra safety.
Research Facilities & Laboratories
Wiring of test benches, measuring instruments, and control systems – precise conductivity and standard compliance ensure reproducible results.
B2B Large-Scale Projects & Industrial Use
Cost-effective solution for bulk buyers: available in coils (50 m, 100 m) or drum lengths. Wide color range simplifies phase identification in complex installations.
Frequently Asked Questions (FAQ) about H07V-U Single Core Cable
What is the difference between H07V-U and H07V-K?
H07V-U is rigid (solid conductor – Class 1), ideal for straight, fixed runs in conduits. H07V-K is flexible (stranded – Class 5), better for tight bends and frequent direction changes in control cabinets.
Can H07V-U be used outdoors or in wet locations?
No – only in protected indoor areas and dry/damp rooms (not directly wet). For outdoor or buried applications, use NYY or equivalent cables.
Is H07V-U halogen-free?
No (PVC insulation). For halogen-free requirements (e.g., public buildings), choose H07Z1-U or similar types.
What is the actual current carrying capacity?
Depends on installation method, ambient temperature, and grouping (see VDE 0298 / DIN VDE 0100-520). Example: 1.5 mm² ≈ 24 A (Method C, 30 °C); always apply correction factors from tables.
Can H07V-U be used as an earthing / protective conductor?
Yes – especially the green-yellow version is approved and widely used for this purpose.
Which standards does H07V-U comply with in 2026?
DIN EN 50525-2-31 (VDE 0285-525-2-31), fire class Eca per EN 50575, flame retardant IEC 60332-1-2.
How do I select the correct cross-section?
1.5 mm² → lighting / controls (up to ~16–20 A); 2.5 mm² → sockets / higher loads (up to ~25–32 A); 4 mm² and above for heavy-duty circuits. Always calculate voltage drop and load.
Is H07V-U suitable for direct embedding in plaster?
Yes – in installation conduits or ducts. Direct embedding without conduit is often permitted, but check local regulations.
From which temperature can installation be carried out?
For fixed installed cable: down to -5 °C; during installation itself, at least +5 °C is recommended to avoid damaging the PVC insulation.
