Choosing the right multi-core cable can be confusing-especially when model names like H05 and H07 look nearly identical. Many engineers, installers, and purchasing managers struggle to decide which cable fits their project best. The wrong choice could lead to safety risks, premature wear, or equipment failure.
In this guide, we'll clearly explain the differences between H05 and H07 multi core cables, including their voltage ratings, materials, and applications-so you can make a confident and informed decision for your next installation.
What Is H05 Multi Core Cable?
H05 multi-core cables are light-duty power cables designed for household and light industrial applications. They comply with IEC 60245 and EN 50525 international standards, ensuring electrical safety and reliability.
Key Technical Specifications
- Rated Voltage: 300/500V
- Conductor: Class 5 fine-stranded copper (flexible)
- Insulation: PVC or EPR (rubber)
- Sheath: PVC or lightweight rubber
- Temperature Range: -25°C to +60°C
- Standards Compliance: VDE, CE, RoHS
Common Types
- H05VV-F: PVC insulated and sheathed, ideal for indoor use.
- H05RN-F: Rubber insulated and sheathed, flexible for portable tools.
- H05RR-F: Lightweight rubber cable for small domestic appliances.
Typical Applications
- Household appliances
- Office and laboratory equipment
- Portable light tools
- Small-scale automation systems
Advantages: Lightweight, flexible, easy to install, and cost-effective.
Limitations: Not suitable for high mechanical stress or continuous outdoor exposure.
What Is H07 Multi Core Cable?
H07 multi-core cables are heavy-duty flexible power cables designed for demanding industrial and outdoor environments. They also comply with IEC 60245 / EN 50525 standards and are engineered for 450/750V rated voltage applications.
Key Technical Specifications
- Rated Voltage: 450/750V
- Conductor: Class 5 fine-stranded copper
- Insulation: EPR (Ethylene Propylene Rubber)
- Sheath: Heavy-duty Neoprene (Polychloroprene) or PUR
- Temperature Range: ‑30 °C ~ +60 °C (up to +85°C short-term)
- Standards Compliance: VDE, CE, CB, RoHS
Common Types
- H07RN-F: The most widely used heavy-duty rubber flexible cable.
- H07BQ-F: PUR sheath offering high abrasion and oil resistance.
- H07ZZ-F: Low smoke, halogen-free cable for public spaces and safety-critical installations.
Typical Applications
- Construction sites and mobile power units
- Industrial machinery and welding equipment
- Outdoor lighting and event installations
- Generators, compressors, and heavy-duty tools
Advantages: Extremely durable, weather-resistant, oil-resistant, and UV-resistant.
Limitations: Slightly heavier and more expensive due to reinforced construction.

- The H05RN-F is perfect for light, portable devices used indoors or under mild conditions.
- The H07RN-F, however, is built for harsh industrial environments, offering superior protection and durability.
How to Choose the Right Cable
Choosing between H05 and H07 depends on your application environment and voltage requirements:
✅ Choose H05 if:
- The installation is indoors.
- You power light equipment or home appliances.
- You prioritize flexibility and lower cost.
✅ Choose H07 if:
- The cable will be used outdoors or under mechanical stress.
- You require high voltage tolerance (450/750V).
- Durability, oil resistance, and weatherproofing are essential.
💡 Tip: Always ensure the cable you select is certified with VDE/CE/CB standards to meet international safety compliance.
