Extended Product Information

FAQs

Is this wire suitable for outdoor use?

This wire is designed for internal switchboard, control device, and protected conduit installations. It is not rated for direct outdoor exposure.

Can I use this for potential equalisation?

Yes, it is permitted for use as a potential equalisation cable, even in applications where other cable tray installations are restricted.

What does Class 5 conductor mean?

Class 5 refers to the flexibility level of the copper strands, indicating the wire is finely stranded and highly flexible compared to rigid (Class 1) or semi-rigid (Class 2) conductors.

Does this cable meet international safety standards?

Yes, it is manufactured in accordance with DIN, IEC, and CE certifications, ensuring it meets rigorous quality and safety benchmarks.

Can I use this wire for 24V DC control circuits?

Yes, while rated for up to 750V, it is perfectly safe and effective for lower voltage control signals.

Troubleshooting

Voltage drop over long runs

Verify the total cable length against your load requirements; 1.5mm² may need to be upsized if the distance exceeds recommended limits for your specific amperage.

Difficult terminal insertion

Ensure the stranded tip is properly twisted and use a suitable wire ferrule to keep strands bundled and prevent splaying.

Insulation damage during pulling

Use cable pulling lubricant and avoid pulling through sharp-edged conduits or over-filling the conduit capacity.

Pros and Cons

Pros

  • High flexibility simplifies routing in control panels
  • Complies with DIN, IEC, and CE standards for safety
  • Excellent temperature tolerance for varied industrial environments
  • Standardized 1.5mm² cross-section fits common connector types

Cons

  • Not suitable for direct installation on open cable trays
  • Single-core design requires secondary bundling for complex circuits
  • Limited to indoor or protected enclosure environments

Setup, Compatibility & Care

For optimal results, ensure the wire is stripped using a professional-grade tool to prevent damage to the copper strands. When installing, adhere to the minimum bending radius specifications to maintain insulation integrity. The cable is fully compatible with standard terminal blocks, crimp lugs, and ferrules designed for 1.5mm² cross-sections. While the PVC insulation is resilient, avoid contact with harsh chemical solvents and ensure the wire is protected from direct UV exposure and excessive moisture if used outside of its specified closed-system environment. Always check local electrical codes before finalizing permanent installations.
