Abstract
A method for manufacturing a sheathing of a cable and a sheathing for a cable is provided where the method includes forming the cable sheathing by extrusion and the sheathing is made of a Pb—Ca—Sn alloy having a composition having from 0.03 to 0.05 weight % Ca and from 0.4 to 0.8 weight % Sn.
Claims20
A method for manufacturing a cable sheathing, wherein the method comprises the following steps:
- applying an extruder comprising:
- a supply of molten Pb—Ca—Sn alloy, and
- a die-head adapted to receive the power cable to be coated and to exit the cable and simultaneously form a coating of supplied Pb—Ca—Sn alloy onto the power cable,
- wherein the Pb—Ca—Sn alloy has a composition comprising of from 0.03 to 0.05 weight % Ca and of from 0.4 to 0.8 weight % Sn, based on the total mass of the alloy and where the balance is Pb and unavoidable impurities.
A sheathing for a cable, wherein the sheathing is made of a Pb—Sn—Ca-alloy having a composition comprising of from 0.03 to 0.05 weight % Ca and of from 0.4 to 0.8 weight % Sn, based on the total mass of the alloy and where the balance is Pb and unavoidable impurities.
