Abstract

1,191,782. Cables. PIRELLI S.p.A. 18 April, 1968 [23 May, 1967], No. 18388/68. Heading H1A. In a cable having a core insulated with paper impregnated with an insulating composition, the ratio Z/P of the sheath corrugations is between <SP>1</SP>/ 25 and <SP>1</SP>/ 15 and the minimum inner diameter of the sheath is greater than the diameter of the core. The cable may be covered with an extruded aluminium sheath under a head of composition thereby preventing the formation of voids.
