Abstract

961,293. Cable sheathing. SIEMENSSCHUCKEKTWERKE A.G. June 6, 1963 [June 14, 1962], No. 22608/63. Heading B3P A cable sheathing extrusion press has a mandrel 13 housing a double-walled cooling tube 19 comprising a cylindrical portion 20, conical portion 21 and single-walled cylindrical portion 22 extending to the tip of the mandrel, the coolant being circulated only through the double-walled portions, and the portions 21, 22 having an external covering 30, 28 respectively of heat-resistant insulating material. The press is used for sheathing an oil-filled cable core 17 with lead or aluminium which is supplied molten through passage 16. Mandrel 13 is secured to the press body 10 by an attachment 11 which carries a plate 31 and clamping screws 33 for pressing the cooling tube 19 tightly against the insulating layers 30, 28 to form a vacuum-tight seal. The cylindrical part 20 may also have an insulating layer. These layers may consist of a tape of glass threads coated with silicone rubber. Water is circulated through inlet port 26 and outlet port 27 and partitions 25 ensure full circulation. After extrusion the sheath is forced down on to the core by a drawing die or by a grooving or corrugating device.
