Abstract

1,098,743. Oil-filled cables. ALLM€NNA SVENSKA ELEKTRISKA A.B. March 17, 1965 [March 18, 1964], No. 11254/65. Heading H1A. An expansion vessel for oil-filled cable has a number of cells 14 made of metallic plate and provided with surfaces so corrugated that when the cells are expanded the corrugations on the surface of one cell enter those on the surface of the adjacent cell. The top and bottom cells are provided with flat surfaces 17 to engage the ends of the oil filled container 1. Expansion vessels of this construction need less oil to fill the spaces.
