  • Halogen-free core insulation and sheath compound to meet special fire protection requirements
  • Transverse watertightness allows permanent submersion in shallow, uncontaminated water: AD8 in accordance with IEC 60364-5-51 and IEC 62440
  • Due to its increased mechanical strength, it is suitable for underground installation in a cable trench with a sand bed, tested using the "Impact-Resistance Test" and the "Crushing-Resistance Test" in accordance with UL 854
  • Cross-linked insulation and sheath materials promote longevity at high temperatures or at high current load, and provide high dielectric strength and a high short-circuit temperature
  • IEC certification allows international use of the product in countries in which the IEC standards are applicable

Application range

  • For unprotected connection of solar modules and inverters in earthed and non-earthed photovoltaic systems according to EN 50618 and IEC 62930
  • For fixed installation and occasional flexing, if necessary freely hanging
  • Underground installation in protective cable conduits only with drainage of accumulated water
  • Underground installation in a cable trench with a sand bed based on VDE 0891-6 and DIN EN 50174-3
  • Expected service life of 25 years in accordance with EN 50618 and IEC 62930 in case of norm-compliant wiring and operation

Product features

  • Weather/ UV resistant per EN 50618 as well as ozone resistant per EN 50396;
    Transversely watertight "AD8" per IEC 60364-5-51/ HD 60364-5-51, IEC 62440, and EN 50525-2-21
  • Flame retardant per IEC 60332-1-2, and Dca classified per EU CPR - Construction Product Regulation (EU) No. 305/2011
  • Halogen-free according to IEC 60754-1 (amount of halogen acid gas),
    Low Corrosiveness of combustion gases according to IEC 60754-2 (degree of acidity)
  • Good notch and abrasion resistance
  • Tested against burial-related, mechanical UL 854 Tests Impact-Resistance and Crushing-Resistance
