FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used in makeups of symmetric communication cables within a shared network or structured cable systems. Disclosed is a cable comprising insulated conductors, twisted into pairs with different pitch of twisting in a common layer, with an outer polymer shell, insulation of each core of which is made in the form of three-layer film-film-corrugated film insulation of equal size throughout the entire section of each conductive core, and the outer film is in contact with the film-corrugated insulation of each conductor along the entire section of each conductor along the entire length of the symmetrical cable.
EFFECT: reduction of relative dielectric permeability of cable conductor insulation and reduction of attenuation factor due to reduction of losses in insulation of conductors and capacitive component of influence between pairs.
