Fire-resistant Optical Fiber Communication Cable DPSv-ng(A)-HF for Safe Installations

Fibre-optic cable for group laying, taking into account the volume of combustible load of cables, in internal electrical installations, as well as in buildings and structures with mass stay of people, including multifunctional high-rise buildings and buildings-complexes, laying in the ground, in cable ducts, also in vertical laying, including shafts. The cable contains dielectric central power element (CPE), modular core, inner polyethylene sheath, protective cover consisting of single or double layer armour made of steel wires and outer sheath made of polymer material, which does not spread burning in group laying and does not emit corrosive gaseous products during burning and smouldering, as well as complete absence of hydrophobic compound
