Abstract

370,149. Cables. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd. and HUNTER, P. V., Hamilton House, Victoria Embankment, London. March 4, 1931, No. 6709. [Class 36.] To prevent the formation of voids in a singlecore cable having impregnated insulation of circular cross-section, the lead sheath of the cable is formed with one or more relatively flat sides which bend. outwardly or inwardly to provide an increased or decreased cross-sectional area of the cable when the impregnating fluid expands or contracts. The Figure shows a stranded conductor 1 insulated with a circular wrapping of impregnated paper 2 and enclosed within a triangular lead sheath 4 formed with rounded corners 5. A conductive layer 3 is applied over the insulated conductor to contact with the flat sides 6 of the sheath 4. Filling pieces 7, consisting of paper with a covering of copper tape or metallized paper, may be disposed in the corners of the sheath. The paper 2 surrounding the conductor may be corrugated as described in Specification 367,445.
