Abstract

1,103,500. Cables. SOC ANON DE TELECOMMUNICATIONS. 31 March, 1966 [1 April, 1965], No. 14202/66. Heading H1A. A cable comprises at least two coaxial pairs of which the outer conductor of each pair is in the form of a metal strip formed into a tube with overlapping edges and is held in contact with the insulation surrounding its inner conductor by a twist imparted to it only during the stranding of a number of such coaxial pairs together. The outer conductors may consist of a copper and a steel strip formed into a composite or bi-metal strip. Three methods of producing such a cable are described. In the method illustrated, the rotary cage of a cablemaking machine has supply reels 32 loaded with insulated inner conductors 31 and additional reels 27 loaded with metal or metal composite strip 28. Also fixed to and rotating with the cage are dies 29 attached to plate 30 in which the metal strip is folded over the insulated inner conductor. A number of the so-formed coaxial pairs are then drawn through a stationary die and twisted together and the resulting cable may be lapped with tape. The composite strip outer conductor may also be formed on the insulation by loading the supply reels 32 with coaxial pairs having a copper strip outer conductor and loading reels 17 with steel strip. In addition to rotating the cradle, the gearing 37 may enable the supply reels 32 to rotate independently of the cradle thus giving a relative twist between elements 31 and 28. In an alternative method, coaxial pairs with metal strip outer conductors contained in the suppy reels of a rotary cage may be stranded directly together, Fig. 4 (not shown) In yet another method, Fig. 6 (not shown),. the supply reels contain insulated inner conductors and two additional sets of reels contain different metallic strips and these are folded in turn over the insulated inner conductor and the coaxial pairs thus formed stranded together in one operation. Cables formed by any of these methods may be stranded together to form composite larger cables.
