The H1Z2Z2-K also proves its worth in special applications, such as near salty air zones or in environments with extreme temperature fluctuations.
# Underground installation of PV cables – what to consider
One major advantage of the H1Z2Z2-K is its suitability for direct burial – without protective conduit. However, certain rules still apply:
## Best practices for installation:
- Bedding in sand or fine-grained material
- Protection from sharp-edged stones by replacing with gravel
- Installation with minimum spacing from other cables
- Marking with warning tape 30 cm above the cable
- Avoid tensile stress during installation
