Abstract

437,098. Cables. SOC. ITALIANA PIRELLI, 21, Via Fabio Filzi, Milan, Italy. May 21, 1935, No. 14796. Convention date, June 2, 1934. [Class 36] A cable comprises a lead sheath, a metallic tape reinforcement, and a winding or windings of a tape made of a metal much more resistant to external chemical attack, when the cable is in use, than the metallic tape reinforcement. An oil-filled cable comprises an oil duct 1, conductor 2, insulation 3, lead sheath 4, windings of bitumened or tarred paper or textile materials 5, 7, a metal tape 6 of high tensile strength such as a brass tape, lead protective tapes 8, 9 and an external covering 10 of paper and bitumened or tarred textile material.
