Product Information

Full details

The LAPP H07V-K is a professional-grade, flexible single-core power and control cable designed for electricians and equipment manufacturers working with control cabinets, lighting fixtures, and industrial machinery. Its primary benefit is high-performance reliability through a fine-wired, class 5 copper conductor that allows for easy routing in tight spaces while maintaining a robust 750V voltage rating. The main caveat for users is that it is intended for fixed installation only and is not designed for continuous movement or harsh outdoor environments without additional protection.

Extended Product Information

FAQs

Is this cable suitable for outdoor use?

The H07V-K is primarily designed for protected fixed installation (e.g., inside conduits or buildings) and is not UV-stabilized for direct, long-term outdoor exposure.

What does the 1.5 mm² rating mean?

This refers to the cross-sectional area of the copper conductor, which determines the amount of current the wire can safely carry. Always verify your circuit's ampacity requirements against local electrical codes.

Can I use this for appliances that move, like a vacuum cleaner?

No. The H07V-K is intended for fixed installation only and does not possess the mechanical durability required for constant flexing or dragging.

Is the cable flame retardant?

Yes, it is flame-retardant according to IEC 60332-1-2, meaning it is designed to prevent the spread of fire along the cable length.

What is the maximum voltage rating?

The cable is rated for an operating voltage of up to 750V AC.

Does this cable require shielding?

No, this is an unshielded single-core wire. If your application is sensitive to electromagnetic interference (EMI), you may need to use shielded conduit or alternative cable types.

Troubleshooting

Difficulty inserting cable into terminal block

Ensure you are using a proper wire ferrule (bootlace ferrule). This bunches the fine strands together, ensuring a secure and safe connection.

Insulation appears stiff or cracked

This is likely due to thermal aging or exposure to temperatures outside the recommended operating range. Inspect the environment for excessive heat sources and replace the affected cable section.

Signal interference in control circuits

Ensure the cable is not running in parallel with high-power cables without adequate shielding or spacing, as H07V-K is unshielded.

Pros and Cons

Pros

  • High flexibility simplifies routing in complex electrical enclosures
  • Verified flame-retardant properties increase safety ratings
  • Robust 750V breakdown threshold ensures circuit stability
  • Internationally recognized quality standards (HAR certified)

Cons

  • Not suitable for applications requiring constant flexing or movement
  • Designed primarily for indoor or protected environments
  • Not intended for direct burial without conduit protection

Setup, Compatibility & Care

To ensure the longevity of your H07V-K installation, follow these professional guidelines:

  1. Environment: Install only in fixed positions within control cabinets, tubes, or ducts. Ensure the ambient temperature remains within the specified range of -40°C to +70°C for fixed installations.
  2. Routing: When pulling the cable through ducts or conduits, avoid using excessive force or sharp-edged tools that could nick the PVC jacket.
  3. Termination: Use appropriate crimp-on ferrules for all terminal connections to prevent stray strands from causing shorts, as the fine-wire design is prone to splaying under direct screw pressure.
  4. Maintenance: Regularly inspect the cable in high-heat areas to ensure the PVC insulation remains supple and shows no signs of hardening or thermal degradation.
