Application

Nexans YMz1K Cca is a halogen free low smoke power cable for general use in construction works subject to performance requirements on reaction to fire. Nexans YMz1K Cca is suitable for application in low voltage installations up to 0.6/1 kV, according to NEN 1010. It meets the requirements according to fire classification Cca-s1,d1,a1 for buildings and civil engineering works with a high fire hazard level (NEN 8012). Available from 35 mm2: Nexans YMz1K Cca ULTIMO FLEX, provided with conductors with increased bendability.

Key features of ULTIMO

  • Faster stripping: up to 80% time savings thanks to the optimized sheath
  • Improved safety: one cut and bend are enough – reducing the risk of injury or conductor damage
  • UV-resistant: suitable for outdoor use, our ables passed the 720 hour test standard EN 50289-4-17 Method A
  • With EPD Environmental Product Declaration: PEP EcoPassport provides full insight into the ecological footprint of the cables
