Product Information

Full details

The Lapp H05V2-K 90° installation wire is designed for electrical installations requiring a flexible, durable, and safe conductor. It is ideal for electricians and DIY enthusiasts working on fixed installations in various environments. Its key benefit is its flexibility and 90°C temperature rating, allowing for easier installation in confined spaces and higher thermal loads. A potential consideration is its specific voltage rating, which should be matched to the application's requirements.

FAQs

What is the difference between H05V2-K and H05V-K?

The primary difference is the temperature rating. H05V2-K is rated for 90°C operation, while standard H05V-K is typically rated for 70°C. The '-K' designation signifies a flexible conductor.

Can this wire be used for mains power supply?

The H05V2-K is suitable for fixed installations with a nominal voltage of up to 500V. Always ensure it meets the specific voltage and current requirements of your mains installation and complies with local electrical codes.

What does CPR Euro fire class eca mean?

CPR Euro fire class 'eca' indicates a basic level of reaction to fire performance as defined by EN 13501-6. It signifies that the cable does not contribute significantly to fire growth under specific test conditions.

Is the green/yellow wire always for grounding?

Yes, in most electrical systems, the green/yellow striped wire is the standard color code for protective earth (ground) conductors, ensuring safety by connecting exposed metal parts to ground.

What is the conductor class 5?

Conductor Class 5 refers to a flexible conductor made of multiple fine, stranded copper wires. This construction provides significantly more flexibility than solid conductors (Class 1) or finer stranded conductors (Class 2).

How should I terminate this wire?

Use appropriate terminals designed for stranded conductors, such as screw terminals or push-in connectors. Ensure the terminal is rated for the wire's cross-sectional area (1mm²) and voltage. Properly strip the insulation and twist any fine strands together before insertion if required by the terminal type.

Troubleshooting

Wire is difficult to bend into place.

While flexible, ensure you are not attempting to force it around excessively tight radii. Gently guide the wire into position. If significant force is needed, re-evaluate the installation path or consider if a more flexible cable type is required for that specific segment.

Connection is loose or intermittent.

Check that the conductor strands are properly seated within the terminal and that the terminal screw is tightened securely. Ensure no stray strands are causing a short circuit. Verify the terminal type is appropriate for stranded conductors of this size.

Insulation appears damaged.

Inspect the entire length of the wire for nicks, cuts, or abrasions. If damage is found, the affected section should be replaced or the wire should not be used.

Wire overheats during operation.

Verify that the current load does not exceed the wire's rated capacity for the installed conditions. Check for proper termination and connection integrity, as poor connections can cause increased resistance and heat. Ensure adequate ventilation in the installation area.

Pros and Cons

Pros

  • High flexibility for ease of installation.
  • 90°C maximum operating temperature for demanding applications.
  • Durable PVC insulation for protection.
  • Standardized green/yellow earth conductor color for safety and compliance.
  • Certified fire performance (Euroclass eca).

Cons

  • Limited to 500V nominal voltage, not suitable for higher voltage systems.
  • PVC insulation may be less resistant to certain chemicals or extreme environmental conditions compared to other materials.
  • Requires careful handling to avoid damage to the fine strands.
  • Specific conductor size (1mm²) may not be suitable for all load requirements.

Setup, Compatibility & Care

Setup:

  1. Ensure the power source is de-energized before making any connections.
  2. Strip the PVC insulation carefully using appropriate wire stripping tools, avoiding damage to the conductor strands.
  3. Terminate the conductor into compatible terminals (e.g., screw terminals, push-in connectors) ensuring a secure connection. The 1.13mm conductor diameter is suitable for many standard electrical connection points.
  4. Follow all local electrical codes and regulations for wiring installations.

Compatibility:

  • This wire is designed for fixed installations and is not suitable for flexible cords that move during operation.
  • Ensure compatibility with the intended voltage (500V nominal) and current carrying capacity requirements of your application.
  • The conductor's 1mm² cross-section dictates its current-carrying capacity, which must be verified against load requirements and applicable standards.

Care:

  • Store in a dry environment, away from direct sunlight and extreme temperatures.
  • Avoid kinking or sharp bends during installation, as this can damage the conductor.
  • Protect the wire from abrasion and chemical exposure that could degrade the PVC insulation.
