An electrical conductor for the transmission of broad band telecommunication signals comprises a plurality of mutually insulated parallel connected metallic tape-like filaments of less than 10 microns thickness on a dielectric substrate with the filaments arranged to ensure equal partition of current in the filaments and the dielectric substrate arranged in a plurality of circumferential layers in relation to the conductor axis. In the embodiment shown in Fig. 1, the tape-like filaments are formed by electrodeposition as oppositely sloped stripes 1, 2 on the sides of a strip of dielectric 3 so that each filament has the form of a flattened helix. The dielectric strip 3 is then rolled into a scroll together with an interleaving strip of dielectric material around a heart, Fig. 2 (not shown). Each filament may be applied as a single longitudinal stripe on one side of a dielectric strip or alternatively the filaments may be applied to the outer surface of a plastic tube in helical formation, the whole structure being subsequently rolled flat. It is shown mathematically in the Specification with reference to the description of Specification 1,098,921 that at a frequency fo lying between the highest operating frequency # max  of the broadband signals and 0À58 # max  the effective resistance of the conductor is equal to or less than four-thirds of the D.C. resistance of the conductor and the effective resistance of the conductor at the frequency # max  does not exceed twice the D.C. resistance if the thickness of the filaments tf 0  are chosen in accordance with the equation: where p is the resistivity of the metal of the filaments, Ks is the ratio of the width of the dielectric strip to that portion of the width occupied by the metal filaments, 6/5 in the described embodiment, d 2  is the outer diameter of the conductor, W is the width of the strip, #o is the operating frequency and F is a factor determined by the internal Cl, and external diameters of the conductor. A conductor in which the thickness of the filaments satisfies the above equation will have a zero temperature coefficient when the frequency of the signals passing therealong is V 3 , the frequency at which the resistance is a minimum.
