Application Areas
These versatile cables are recommended for:
- Underground networks for low voltage distribution
- Service connections (underground supply networks)
- Industrial installations and equipment connections
- Building wiring systems and riser columns
- Outdoor lighting installations
- Areas with high operating temperatures
- Environments requiring high resistance to solar radiation and atmospheric agents
- Fixed installations in cable ducts, trays, or directly fixed to walls
- Walkways and empty constructions (without additional mechanical protection)
- Underground installations with appropriate mechanical protection (slabs, tiles, or bricks)
Note: Not recommended for installation in ground flooded for more than two months per year. When used in explosive risk areas with appropriate mechanical protection, current carrying capacity must be reduced by 15%.
Installation Recommendations
Bending Radius
- Single core cables: 6 times the cable diameter
- Multi-core cables: 8 times the cable diameter
Maximum Pulling Stress
- 5 kg/mm² of copper cross section
Current Carrying Capacity
Current ratings depend on:
- Number of cores
- Cross-sectional area
- Installation method (free air or buried)
- Ambient temperature
- Grouping with other cables
Note: Correction factors must be applied in case of high ambient temperatures or when cables are installed in groups.
Core Identification & Color Coding
