An assembly is provided including two members capable of relative rotation about a common axis, and with electrical interconnections extending between the two members, the assembly, being for example, part of a gimbal system, wherein the electrical interconnections may be divided into two groups, selected such that, because of the voltages, and/or currents, carried by the electrical interconnections, it is desired that the electrical interconnections of one group are screened electrically from the electrical interconnections of the other group, by a screen which does not extend along the whole length of either group. An annulus-defining, rotatable, member is provided which is closed at one end, between radially inner and outer, constituent member sections, and a second, fixed, hollow, cylindrical member divides the annulus into radially inner and outer constituent sections, wherein a tape, comprising one group of electrical interconnections, extends between the intermediate member and the outer member section; and another tape, comprising the other group of electrical interconnections, extends between the intermediate member and the inner member section; the two tapes being loosely coiled, in the same direction, in the associated inner and outer annular sections, the assembly being so constructed and arranged that the tapes are screened electrically from each other by the intermediate member.
