Choosing the right wire for your electrical or industrial project can directly impact safety, performance, and long-term reliability. Among the most common flexible single-core wires, H05V-K and H07V-K often cause confusion due to their similar appearance but different specifications. In this guide, we'll clearly explain their differences-from voltage ratings to applications-so you can make the right decision for your project while ensuring top-quality results and cost efficiency.
Basic Definition and Standards
Both H05V-K and H07V-K are flexible PVC-insulated single-core copper wires designed for power, control, and industrial automation systems.
- H05V-K is rated for 300/500V, compliant with IEC 60227-3 / EN 50525-2-31 standards.
- H07V-K is rated for 450/750V, designed for higher voltage and mechanical strength under the same international standards.
Both use fine-stranded copper conductors (Class 5) and are available in various colors for easy circuit identification.

Core technical parameters of H05V-K and H07V-K
| Parameter | H05V-K | H07V-K |
|---|---|---|
| Rated Voltage | 300/500V | 450/750V |
| Conductor Type | Fine stranded copper, Class 5 | Fine stranded copper, Class 5 |
| Insulation Material | PVC (Polyvinyl Chloride) | PVC (Enhanced for higher voltage) |
| Temperature Range | -5°C to +70°C | −15 °C 到 +70 °C |
| Flexibility | High flexibility | High flexibility, higher durability |
| Typical Applications | Control panels, appliances, low-voltage wiring | Industrial machinery, power distribution, automation systems |
| Compliance Standards | IEC 60227 / EN 50525-2-31 | IEC 60227 / EN 50525-2-31 |
| Available Colors | Red, blue, black, yellow/green | Black, blue, yellow/green |
Application Scenarios: Which One to Choose?
H05V-K
Ideal for light-duty and indoor applications such as:
- Electrical cabinets and control panels
- Home appliances and low-voltage equipment
- Signal and data wiring in dry environments
H07V-K
Recommended for industrial and heavy-duty environments where higher voltage or temperature resistance is required:
- Power distribution systems
- Automation equipment and motor connections
- Industrial control panels exposed to mechanical stress
Cost and Value Analysis
| Aspect | H05V-K | H07V-K |
|---|---|---|
| Material Cost | Lower | Slightly higher |
| Durability | Suitable for standard environments | Enhanced insulation and voltage endurance |
| Target Application | General electrical use | Industrial and high-load systems |
| Overall Value | High cost-efficiency | High performance and safety margin |
If your system operates under standard voltage and dry indoor conditions, H05V-K offers excellent value.
For high-voltage or industrial-grade systems, H07V-K ensures superior safety and longevity.

Safety and Certification Standards
Both cable types meet major international safety standards including:
- IEC 60227 / EN 50525-2-31
- CE marking
- RoHS and REACH compliance
When sourcing cables, always ensure your supplier provides proper testing, certification, and traceability to guarantee long-term safety and compliance in all applications.
