Product Information

Full details

The LAPP H07V-K single core cable is an ideal solution for electrical engineers and technicians requiring reliable, flexible wiring for control cabinets, instrumentation panels, and motor starters. This high-quality wire offers excellent versatility with its fine-strand copper construction and flame-retardant PVC insulation, supporting systems up to 750V AC. One caveat to keep in mind is that while it is robust for internal equipment wiring, it is primarily designed for fixed installations and should not be used in high-flexibility dynamic applications like drag chains.

Extended Product Information

FAQs

Can I use this cable outdoors?

This cable is designed for fixed indoor installations. While it is robust, it should be protected from direct UV exposure and moisture if used in an outdoor environment.

What does the H07V-K designation mean?

It is a European standardized designation: H stands for HAR-certified, 07 for 450/750V rating, V for PVC insulation, and K for flexible conductor class.

Is this cable shielded?

No, this is a single core, unshielded wire designed for power and control signal transmission.

What is the minimum bend radius for this cable?

While highly flexible, always follow the general rule of maintaining a bend radius of at least 4 to 6 times the outer diameter to prevent internal strain.

Can this be used for motor cabling?

Yes, it is suitable for motor starters and control wiring, provided the current rating is appropriate for the motor's power requirements.

Is the copper tinned?

No, this specific model (4520063) features bare copper strands.

Troubleshooting

Difficulty pulling wire through tight conduit

Use an appropriate cable lubricant to reduce friction and verify the conduit bend radius meets industry standards.

Voltage drop in long cable runs

Recalculate the required conductor cross-section based on the total load and distance; the 4 mm² size is ideal but may need upgrading for significantly long runs.

Insulation damage during installation

If the PVC jacket is nicked, do not use the cable for high-voltage applications. Cut out the damaged section or replace the wire to prevent short-circuiting.

Pros and Cons

Pros

  • High level of flexibility for fixed indoor installations
  • Flame-retardant safety rating
  • Suitable for a wide range of industrial equipment
  • Reliable operation in extreme temperatures
  • HAR-certified quality for international compliance

Cons

  • Not suitable for continuous movement or robotic drag chains
  • Requires proper strain relief for external connections
  • Indoor-focused design limiting direct outdoor exposure

Setup, Compatibility & Care

To ensure maximum service life and safety, adhere to the following installation guidelines:

  1. Fixed Installation: Use this cable for fixed wiring environments. When installing, ensure it is placed in tubes, closed installation ducts, or conduits where possible.
  2. Surface Mounting: The cable can be laid directly on racks or troughs only when used as a potential equalization conductor.
  3. Handling: Avoid sharp edges during the pulling process to prevent nicks to the PVC insulation.
  4. Temperature: Ensure the environment does not exceed the 70 °C maximum for fixed installations to avoid long-term degradation of the insulation material.
  5. Maintenance: Periodically inspect connections to ensure terminals remain tight, as vibration can eventually loosen connections in high-density panels.
