There the simplified formulae for engineering calculation of effectiveness of braiding have been developed to study the braiding properties of cable articles. The method of triaxial line has been chosen to measure the characteristics of effectiveness of braiding. The determination manner of error in measurement at the triaxial lines, the control manner of coupling impedance of cables have been developed for the first time. TL-1000 triaxial line which allowed to expand frequency range in measurement up to 1000 MHz has been created. The measurement technique for TL-1000 has been developed. The results have been introduced in the Special Design Office of Cable Industry, MytishchiAvailable from VNTIC / VNTIC - Scientific & Technical Information...
