  • For outdoor applications
  • Robust against mechanical impacts, Burial in professionally made cable trench inside or without protection system
  • Reduction of flame propagation and of toxic combustion gases in the event of fire
  • Inside the EU, and particularly on site, applicable for many building types as per local, legal implementation of EU CPR - Construction Product Regulation (EU) No. 305/2011, thanks to Dca Classification
  • 25 years in expectable lifespan under normal use conditions as defined in EN 50618

Application range

  • For free and stationary or for freely suspended outdoor and indoor cabling between the solar modules, or between the module strings and the DC/AC inverter, for example in line with HD 60364-7-712 on PV systems, and EN 50618 on H1Z2Z2-K cable type, etc....; Short circuit and earth fault protected per EN 50618, Annex A, and per HD 60364-5-52
  • As per EN 50618, Annex A, inside electrical installation pipe/ duct/ channel, plaster, and appliance, as well as inside or connected to double insulated/ protected appliance or system of protection class II
  • Photovoltaic systems with DC system voltage up to 1800 V to ground
  • AD8: Permanent water contact and submersion down to 1 metre in water depth
  • Increased, mechanical robustness, for instance in the event of impact;
    Burial in Ground in professionally made cable trench (see Section 4.2 of VDE 0891-6, or Section 300.5 in Article 300 of NFPA 70/ NEC - National Electrical Code of the USA) with or without additional protection system, such as tube/ duct/ conduit for burial in ground;
    Where additional protection system for burial in ground is used, internal waterlogging of contaminated water in contact with the cable's outer sheath must be avoided.
