    (54) Cable arrangement for use in a multiplex transmission system


    (57) A cable unit (10) comprises a pair of power supply conductors (1,2) of an elongated strip shape extending parallelly, being opposed each other. The two conductors (1,2) are separated as close as possible with a possible distance for assuring a desired withstand voltage. A pair of signal conductors (3,4) are disposed one side of the power conductors (1,2) at positions corresponding to the center between the two power supply conductors (1,2) and extending parallelly along the power supply conductors (1,2). The respective conductors (1-4) are covered with suitable insulation layers (11).
