Product Information

Full details

The Lapp H07V-K installation wire is a high-performance, flexible conductor designed for electrical contractors and panel builders requiring reliable, flame-retardant wiring for control cabinets and electronic equipment. With a 1.5mm2 cross-section and 750V rating, it offers excellent conductivity and ease of installation in tight spaces; however, users should note it is primarily suited for indoor, fixed environments rather than exposed outdoor exposure.

FAQs

Can this wire be used outdoors?

The H07V-K is designed for fixed indoor installations in tubes, ducts, or within enclosures; it is not recommended for exposed outdoor use.

What is the primary material of the conductor?

The conductor is made of fine-stranded bare copper.

Does this wire meet fire safety standards?

Yes, it is flame-retardant according to IEC 60332-1-2 and meets CPR Euro fire class Eca requirements.

What is the maximum voltage this wire can handle?

It is rated for a maximum operating voltage of 750V.

Can I use this for rack installation?

Yes, it can be laid on racks or troughs only when used as a potential equalisation conductor.

What is the diameter of the wire?

The outer diameter is 3.4mm.

Troubleshooting

Difficulty stripping the insulation

Ensure you are using a precision wire stripper matched to the 1.5mm2 diameter to avoid cutting the fine copper strands.

Wire feels stiff in very cold conditions

While rated for -40°C, PVC can stiffen at lower temperatures; allow the wire to reach room temperature before attempting complex routing.

Pros and Cons

Pros

  • High flexibility for easier installation in tight spaces
  • Excellent flame-retardant properties for improved fire safety
  • Reliable, high-quality copper core ensuring consistent conductivity
  • Wide operating temperature range for diverse industrial environments
  • Certified for compliance with major European standards

Cons

  • Not intended for direct exposure to harsh outdoor elements
  • Strict installation methods required for rack and trough laying
  • Requires professional handling for termination to maintain safety

Setup, Compatibility & Care

For optimal results, ensure the wire is installed in accordance with local electrical codes. When stripping the PVC insulation, use precision wire strippers to avoid nicking the fine copper strands, as damage to these strands can degrade performance. While it is suitable for installation in tubes, under plaster, or in closed ducts, it should not be used in environments where it will be subject to constant movement or mechanical stress. When used on racks or troughs, it must strictly be used as a potential equalisation conductor. Regularly inspect the insulation for signs of cracking or heat-related degradation, especially if the wire is operated near its maximum thermal limit of 70°C.
