What Is H05VVC4V5-K Cable?
The H05VVC4V5-K is a specialized European standard power and control cable featuring dual sheathing and copper braided shielding. These cables are CE certified and designed for applications requiring protection against electromagnetic interference while maintaining flexibility in industrial environments. With its oil-resistant outer jacket and robust construction, the H05VVC4V5-K has become a preferred choice for machinery builders and industrial equipment manufacturers across Europe and globally.
Decoding the H05VVC4V5-K Designation
Understanding the cable designation helps in selecting the right product for specific applications:
- H: Indicates compliance with European Harmonization standards
- 05: Denotes rated voltage of 300/500V
- First V: Polyvinyl Chloride (PVC) insulation material
- Second V: PVC inner sheath
- C4: Four-core conductor configuration with copper braid shielding
- V5: Oil-resistant PVC outer sheath
- K: Fine-stranded flexible copper conductors
This systematic naming convention follows European cable identification standards, allowing engineers and procurement specialists to quickly identify cable characteristics from its model number.
Construction and Materials
The H05VVC4V5-K features a sophisticated multi-layer construction designed for durability and performance:
- Conductor: Multi-strand fine copper wires (class 5 flexible stranding according to IEC 60228)
- Insulation: PVC T12 compound providing excellent electrical properties
- Inner Sheath: PVC TM2 material surrounding the insulated conductors
- Shielding: Tinned copper braid with approximately 85% coverage
- Outer Sheath: Oil-resistant PVC TM5 compound (typically black or transparent)
The dual-sheath design provides enhanced mechanical protection while the copper braiding effectively shields against electromagnetic interference, making it ideal for sensitive control applications in electrically noisy environments.

Applications and Industries
The H05VVC4V5-K cable excels in environments requiring reliable signal transmission with protection against interference:
- Industrial Machinery: Control systems for CNC machines, robotics, and automated production lines
- Material Handling: Conveyor systems and packaging equipment
- Food and Beverage Processing: Bottling plants and brewery machinery (where oil resistance is essential)
- Automotive Manufacturing: Assembly line equipment and testing stations
- Building Automation: Control systems for HVAC and facility management
- Medical Equipment: Where signal integrity is critical
This cable is specifically designed for medium mechanical stress applications with frequent movement but no significant tensile forces. It performs reliably in dry, damp, and wet indoor environments, though it is not recommended for permanent outdoor exposure or direct burial applications.
Installation Best Practices
Proper installation maximizes the performance and lifespan of H05VVC4V5-K cables:
- Shield Termination: Ensure the copper braid shield is properly grounded at one end to prevent ground loops while maintaining effective EMI protection
- Bending Considerations: Respect minimum bending radii during installation to prevent damage to conductors and shielding
- Routing Guidelines: Separate power and signal cables where possible; when crossing is necessary, maintain 90° angles
- Temperature Management: Avoid routing near heat sources exceeding the cable’s temperature rating
- Strain Relief: Implement proper strain relief at connection points to prevent conductor fatigue
- Environmental Protection: While oil-resistant, prolonged exposure to aggressive chemicals should be avoided
Advantages Over Standard Cables
The H05VVC4V5-K offers several performance benefits compared to non-shielded alternatives:
- Superior EMI Protection: Copper braid shielding minimizes interference from motors, VFDs, and other electrical noise sources
- Enhanced Durability: Dual-sheath construction provides excellent resistance to abrasion, crushing, and oil exposure
- Flexibility: Fine-stranded conductors allow for repeated bending in moving applications
- Safety Compliance: Meets stringent European safety standards for fire resistance and electrical performance
- Long Service Life: Quality materials and construction reduce replacement frequency and downtime
Sizing and Selection Considerations
When selecting H05VVC4V5-K cable for your application, consider:
- Conductor Cross-Section: Available from 0.5mm² to 2.5mm² (common sizes include 0.75mm² and 1.0mm²)
- Number of Cores: Typically 2, 3, 4, 5, 7, 12, 18, or 25 cores depending on application requirements
- Color Coding: Conductors follow VDE-0293 color standards for easy identification
- Length Requirements: Available in standard drum lengths with custom cutting options
For specialized applications requiring extreme flexibility or wider temperature ranges, consult with cable manufacturers about modified versions or alternative cable types that might better suit your specific needs.
