The Lapp H07V-K is a premium 1.5mm² flexible installation wire designed for professionals and hobbyists performing fixed wiring in power systems, control cabinets, and device setups. It provides a reliable, flame-retardant power distribution solution that is easy to route thanks to its fine-wired class 5 copper construction. While it excels in static environments, it is not intended for high-flex mechanical movement or outdoor exposure without protective conduits.

It is intended for fixed, protected installations. If used outdoors, it must be housed within a suitable UV-resistant conduit or protective tube.
It is a class 5 fine-wired stranded copper conductor, which provides much higher flexibility than solid wire.
The wire is rated for a permitted operating temperature range up to 80°C.
Yes, it is flame retardant according to IEC 60332-1-2 and complies with Euro fire class Eca.
No, this is a low voltage cable rated for a maximum of 750V; it is not suitable for high-voltage transmission lines.
The HAR marking indicates international endorsement of the cable based on testing by European national certification institutes.
Verify the total length of the run and ensure the 1.5mm² cross-section is sufficient for the load; consider a higher gauge if the drop exceeds acceptable limits.
Check conduit paths for sharp edges or burrs and use cable lubricants if necessary to minimize friction during the pull.
Ensure all terminals are properly crimped or torqued according to manufacturer specifications; loose connections are the most common cause of heat buildup.
For setup, ensure that the wire is used within its rated 450/750V range and never exceeds the maximum load capacity for a 1.5mm² cross-section. When stripping the PVC insulation, use a calibrated wire stripper to avoid nicking the fine copper strands. For long-term care, keep the wire away from harsh industrial solvents that could degrade the PVC jacket. Ensure all terminations are clean and tight to prevent resistive heating at connection points. When routing, maintain a reasonable bend radius to prevent stress on the internal conductor.
