Cable for suspension on supports of communication lines, lighting, between buildings and constructions, inside buildings and constructions and operation at ambient temperature from minus 60 °? to 70 °?.
The outer sheath is made of polymer compositions with consideration of application: at cable entry into the premises from polymer compositions, not spreading burning; in other cases - from polyethylene; power peripheral elements from fibreglass bars, the central optical module.
