FAQs

What is the nominal conductor cross-section?

The nominal conductor cross-section is 0.25mm².

What is the maximum operating temperature for this wire?

The wire can withstand processing temperatures up to +70°C.

Can this wire be used for mains power?

No, this wire has a nominal voltage rating of 50V and is intended for low-voltage applications only.

What does 'Class 5' conductor mean?

Class 5 refers to the flexibility class of the conductor. Class 5 conductors are finely stranded, making them highly flexible and suitable for applications requiring frequent bending or movement.

What material is the insulation made of?

The conductor insulation is made of polyvinyl chloride (PVC).

What are the available colors for this wire type?

This specific product is grey. Other colors like White, Blue, Black, Orange, Red, and Green are available in the LAPP LiY installation wire range.

What is the outer diameter of the wire?

The outer diameter of the wire is 1.3mm.

Troubleshooting

Intermittent signal loss

Check for loose connections at both ends of the wire. Ensure the conductor is fully inserted into terminals and securely fastened. Inspect the wire for any physical damage along its length.

Wire is too stiff for the application

Verify that the correct wire gauge and flexibility class (Class 5) is being used. For applications requiring even greater flexibility, consider alternative cable types if available.

Overheating during operation

Confirm that the wire's current load does not exceed its capacity, although specific current ratings are not provided, low voltage wires of this gauge are typically for signal or low power. Ensure the ambient temperature does not exceed the 70°C maximum operating temperature. Check for any potential short circuits or excessive resistance in the connected components.

Pros and Cons

Pros

  • High conductor flexibility for ease of installation.
  • Durable PVC insulation offers good protection.
  • Compact size is suitable for space-constrained applications.
  • Rated for a wide temperature range (-30°C to +70°C).
  • Reliable for low-voltage control and signal applications.

Cons

  • Limited to 50V nominal voltage, not suitable for mains power.
  • 70°C maximum temperature rating restricts use in high-heat areas.
  • PVC insulation may not be suitable for all chemical environments.
  • Single conductor wire requires separate insulation for live/neutral/ground.

Setup, Compatibility & Care

Setup:

  1. Stripping: Use a wire stripper suitable for fine-gauge wires to carefully remove the PVC insulation without nicking the conductor strands.
  2. Termination: Connect the stripped conductor to the appropriate terminal, screw lug, or connector. Ensure a secure and tight connection.
  3. Routing: Route the wire neatly, avoiding sharp bends that could stress the conductor or insulation. Secure with cable ties or clips as needed, ensuring not to overtighten.

Compatibility:

  • This wire is designed for low-voltage DC or AC circuits up to 50V.
  • Compatible with standard low-voltage connectors, terminal blocks, and crimp terminals.
  • Suitable for use with other LAPP LiY series cables and accessories.

Care:

  • Keep the wire clean and free from dust and debris.
  • Periodically inspect the insulation for any signs of damage, such as cuts, abrasions, or degradation, especially in areas exposed to environmental stress.
  • Ensure connections remain tight and free from corrosion.
