Core of soft copper wire with PI, twisted in pairs with steps, not equal and not multiples of each other.Pairs are twisted in a core by unidirectional twisting.A sheath of cold-resistant thermoplastic elastoplast is applied over the core.High-frequency twisted pair cables for structured cable systems are designed for stationary horizontal and vertical laying inside buildings and structures, for stationary horizontal and vertical external laying on the walls of buildings and suspension on overhead communication lines, for operation in the frequency range up to 100MHz (category 5 and 5e according to GOST R 54429-2011) and ISO/IEC 11801.Cables are manufactured in climatic version U, categories of placement1,2,3,4 according to GOST15150. Cables can be operated at ambient temperature minus 60 to 60 0C. Cable installation is made at the temperature not lower than minus 40C.Minimum permissible bending radius at laying and installation should be not less than 8 maximum outer diameters of the cable.
