DEVICE FOR INFORMATION SIGNAL TRANSMISSION LINE

摘要

PURPOSE:To eliminate the attenuation of an information signal at a frequency corresponding to the arrangement interval of terminal connecting insulators by making the static capacitance produced among plural signal transmission conductors depending on the position of intermediate support fixing insulators and the position of terminal connection insulators equal to each other. CONSTITUTION:The equivalent dielectric constant of the terminal connection insulator 4 is decreased by providing a hole 4a penetrating in the lengthwise direction of signal conductors 1, 2 by using a drill or the like in a way that the static capacitance C1 caused between the two signal conductors 1, 2 at the position of the intermediate part support and fixing insulator 3 is made equal to the static capacitance C2 caused between the two signal conductors 1, 2 at the position of the terminal connecting insulator 4. Thus, the attenuation of the information signal having a frequency corresponding to the arrangement interval of terminal connection insulators being components of the transmission line unit.
