Abstract
425,789. Conductors. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Jan. 25, 1934, No. 2633. Convention date, Jan. 28, 1933. [Class 36] A high-frequency conductor of the litzendraht type, particularly for use in continuously loaded cables and for the windings of loading coils and repeater coils, is formed by stranding or plaiting together bare wires and then reducing the cross section of the composite strand, by rolling or drawing, to improve its filling factor, the wires being insulated from one another either during or subsequently to the operation of reducing the cross section. The insulation of the wires may be effected by heating the conductor in an oxidizing atmosphere, or by impregnating the conductor with an insulating substance which is naturally liquid or which can be rendered liquid by heat or solvents ; or an insulating material, such as boron or silicon hydride which can be introduced in gaseous form between the wires, may be employed. To facilitate the insulating process, the spaces between the wires may be temporarily enlarged by applying a backward twist or axial compression to the conductor. In a continuously loaded conductor the insulating material, which is introduced between the wires after the annealing of the loading tape, may also serve as a pressure equalizing material.
