RK / РК - coaxial cable with solid insulation of regular heat resistance

Application

Coaxial cables with solid insulation of typical heat resistance are produced according to the GOST 11326.0-78. Coaxial radio-frequency cables represent an independent class of radio-frequency lines of information transfer and used for transmission of radio and video signals in a range from meter to centimeter wave lengths. Radio-frequency cables are applied in antenna and feeding devices, in radio - and television receivers, for inside - and interblock connections in radio-electronic equipment. Coaxial type cables which in comparison with two-core cables possess higher noise immunity and very small losses in a wide range of frequencies are the mostly widesread. The working range of frequencies of coaxial radio-frequency cables is from 10*(7) to 10*(10) Hz.
