Abstract
1322752 Electric cables BRITISH INSULATED CALLENDER'S CABLES Ltd 19 April 1971 [12 Feb 1970] 6865/70 Heading H1A A telecommunications cable comprising a plurality of pairs 2 of twisted together insulated conductors 3 has one or both the interstitial spaces present within the circumscribing cylinder of each of at least two of the pairs, occupied by an elongate member 4 wholly of insulating material to prevent displacement of the pairs with respeot to each other. Each elongate member may be integral with, or secured to, one of the insulated conductors of the pair with which it is associated (Fig. 3, not shown), or the other elongate member, if present, associated with that pair. As shown six pairs 2 of copper conductors insulated with polythene 3 are helically laid around a polythene core 1. The interstitial spaces of each pair are occupied by elongate polythene members 4, the two members associated with each pair are integral with a polythene web 5. The cable is completed by a lapping of polyester film tape 6, a covering 7 of polythene, a screen 8 comprising a lapping of copper tape and finally a sheath of polythene 10. The elongate members 4 may have flexible reinforcing members, e.g. an insulating strand or thread embedded therein. Reference has been directed by the Comptroller to Specification 1,108,919.
