OPTIC COMMUNICATION CABLE Russian patent published in 2010 - IPC H01B11/22 

FIELD: electricity.

SUBSTANCE: invention is related to the field of electrical engineering and may be used in structures of optic communication cables in process of arrangement of fibre-optic communication lines. Optic communication cable, comprising optic fibres in dielectric tubes, central dielectric reinforcing element, hydrophobic filler, dielectric tape, intermediate dielectric shell and armoured cover made of one lay of dielectric tapes, every of which comprises power elements of various diametre, and metal power element in the centre of each odd dielectric tape, having largest diametre, protrudes on external side of communication cable beyond dielectric tape limits by not more than half of its radius, and both extreme metal power elements of each dielectric tape protrude beyond limits of dielectric tape by value of not more than half of its radius along full circumference of cable, and metal power element in the centre of each even dielectric tape, having largest diametre, protrudes from internal side of communication cable beyond the limits of dielectric tape by not more than half of its radius, the second lay of dielectric tapes has also been introduced, which is similar to the first one.

EFFECT: invention makes it possible to eliminate danger of personnel injury and cable damage with increase of its mechanical strength.
